Q: What are the advantages and disadvantages of a home battery?

Advantages: a home battery increases your self-consumption of solar energy by up to 80%, lowers your energy bill and makes you less dependent on the grid. In addition, it provides protection against price fluctuations, especially when combined with dynamic energy tariffs. Disadvantages: the initial investment is relatively high, and you need a suitable place to safely install the battery - preferably indoors or in a well-ventilated location. At SunCharged, we're happy to help you determine whether a home battery is a smart choice in your situation.

Question 1

What does a home battery cost on average in the Netherlands?

Accepted Answer

The cost of a home battery varies widely and depends entirely on your situation and needs. There are compact plug-and-play batteries that you plug directly into the wall socket, as well as complete systems with large storage capacity, advanced inverters and even off-grid capabilities. The complexity of the installation also plays a role in the total price.

At SunCharged, we look at your energy consumption, house type and future plans with you. Based on that, we create a custom quote, so you can be sure you're getting what's right for you.

Question 2

How much can I save with a home battery on my energy bill?

Accepted Answer

With a dynamic energy contract and a home battery, you always benefit from the lowest energy rate of the day. Exactly how much you save depends on several factors such as your energy consumption, solar production, the capacity of your battery and current power prices. Especially with large price differences in the energy market, a smart battery can make all the difference. By charging when power is cheap and discharging when rates are high, you maximize your solar power as well as market prices. At SunCharged, we are happy to help you understand your personal savings potential.

Question 3

Is it profitable to purchase a home battery now while the net metering scheme is still active?

Accepted Answer

Although the net metering scheme remains in effect until 2027, a home battery can already be profitable if you have a dynamic energy contract or want to maximize self-consumption.
Additionally, you'll be prepared for the phasing out of the net metering scheme and benefit from price stability.
We're happy to advise you on the best timing for your specific situation.

Question 4

How exactly does a home battery work with solar panels?

Accepted Answer

A home battery stores excess solar power that you don't use immediately.
When your panels produce less or no electricity (for example, in the evening or during cloudy weather), you first use the stored energy from your battery before drawing power from the grid.
This increases your self-consumption of solar energy to up to 70-80% and reduces your dependence on the electricity grid.

Question 5

What is the lifespan of a home battery?

Accepted Answer

At SunCharged, we select only high-quality home batteries from reputable manufacturers that are designed for long life. Manufacturers often provide a warranty based on charge and discharge cycles - around 6,000 cycles is common today, which equates to 15 years or more with normal use.

The exact lifespan depends on the battery type, usage pattern and number of cycles. Lithium iron phosphate (LiFePO4) batteries typically offer the longest life. Even after the warranty period expires, most batteries will still function, although the storage capacity does decrease over time.

Question 6

Can I live completely off-grid with a home battery and solar panels?

Accepted Answer

Full off-grid living is legally and practically difficult in the Netherlands. A grid connection is required by law for homes. Nevertheless, there are technically possible solutions for people who want maximum independence. Think of systems with large battery capacity, smart energy storage and possibly an emergency generator as backup for periods with little sun, such as in winter.

For most households it makes more sense to stay connected to the grid as a safety net. However, with a properly sized system, you can significantly increase your self-sufficiency to about 70-80% on an annual basis.

At SunCharged, we design systems that maximize your independence, while maintaining grid security.

Question 7

How much capacity (kWh) do I need for my household?

Accepted Answer

For an average Dutch household (3,500 kWh/year) a 5 kWh battery is usually sufficient.

The ideal capacity depends on your daily power consumption, usage pattern, the power of your solar panels and the functionalities you want to use.
At SunCharged we analyze your specific situation to determine the perfect battery size that fits your energy needs, desires and budget, without unnecessarily investing in overcapacity.

Question 8

What happens if the battery is full and I'm still generating solar energy?

Accepted Answer

If your battery is fully charged and you're generating more solar energy than you're using, the excess power is automatically fed back into the electricity grid.
Until 2027, you'll still benefit from the full net metering scheme.
After that, you'll receive a feed-in tariff from your energy supplier.
With a smart energy management system, you can also choose to run certain appliances extra when there's a surplus.

Question 9

Is there a subsidy available for home batteries in the Netherlands?

Accepted Answer

In 2025, there is still no national subsidy for home batteries, but there are local initiatives and pilot projects in various municipalities.
Additionally, you can benefit from VAT refunds if you have a dynamic energy contract and your battery can trade on the energy market.
At SunCharged, we closely monitor all subsidy opportunities and advise you on the schemes you can use.

Question 10

What are the advantages and disadvantages of a home battery?

Accepted Answer

Advantages: a home battery increases your self-consumption of solar energy by up to 80%, lowers your energy bill and makes you less dependent on the grid. In addition, it provides protection against price fluctuations, especially when combined with dynamic energy tariffs.

Disadvantages: the initial investment is relatively high, and you need a suitable place to safely install the battery - preferably indoors or in a well-ventilated location.

At SunCharged, we're happy to help you determine whether a home battery is a smart choice in your situation.

Question 11

Is it possible to combine a home battery with a dynamic energy contract?

Accepted Answer

Absolutely!
A home battery combined with a dynamic energy contract is an excellent strategy.
You can charge your battery during hours with low electricity prices and discharge when prices are high.
This can significantly increase your savings, up to €500-600 per year.
At SunCharged, we advise on smart energy management systems that automatically respond to price fluctuations, allowing you to maximize the benefits of both your battery and dynamic rates.

Question 12

How much space does a home battery take up?

Accepted Answer

A modern home battery takes up approximately the space of a small cabinet or washing machine (30-100 liters).
Most models have a wall mount and protrude about 20-30 cm from the wall.
We work with you to find the ideal location in your home, such as a garage, utility room, or technical room.
At SunCharged, we consider not only technical aspects but also aesthetics, so that the battery fits nicely in your home.

Question 13

Do I need a permit for a home battery?

Accepted Answer

In most cases, a permit is not required for a home battery.
However, for apartments or monumental buildings, permission from the VvE or municipality may be required.
At SunCharged, we assist you with all necessary documentation and can contact your VvE or municipality if necessary to ensure a smooth process.
We ensure that your installation fully complies with all local regulations and safety standards.

Question 14

Can I also receive a feed-in tariff in addition to battery usage?

Accepted Answer

Absolutely.
When your battery is fully charged and you produce more electricity than you consume, the excess energy is fed back into the grid.
For this, you receive a feed-in tariff from your energy supplier.
Until 2027, you will still benefit from the full net metering scheme.
A smart energy management system can help optimize the balance between own use, storage, and feed-in for maximum financial benefit.

Question 15

What happens in the event of a power failure - will my battery still work?

Accepted Answer

This is not standard. In a normal installation, your home battery shuts down during a power outage. This is not only because of safety, but also because the power could otherwise flow into the public grid through your smart meter. To still maintain power during an outage, a closed system must be created in the home. This can be done with a backup function or an off-grid capability, which keeps your battery working completely autonomously. At SunCharged, we are happy to advise on these solutions and help you choose what suits your situation and budget.

Question 16

How many charge and discharge cycles does a battery have on average?

Accepted Answer

Modern home batteries offer between 5,000 and 10,000 full charge and discharge cycles, depending on the type and quality.
With daily use, this means a lifespan of 13 to 27 years.
Lithium iron phosphate (LiFePO4) batteries perform best in this regard.
At SunCharged, we select batteries with the highest cyclic lifespan and excellent warranty terms, so you can use your energy storage system worry-free for years to come.

Question 17

Is there a difference between AC- and DC-coupled batteries?

Accepted Answer

Yes, there is an important difference: DC-coupled systems connect the battery directly to the solar panels before the inverter, which is 3-5% more efficient but requires a compatible hybrid inverter.
AC-coupled systems place the battery on the alternating current side after the inverter, which is easier to install and more flexible with existing solar panels.
At SunCharged, we advise on which coupling is best suited to your situation, taking into account your existing installation and future expansion plans.

Question 18

Can I use my electric car as a home battery (V2H)?

Accepted Answer

Yes, with Vehicle-to-Home (V2H) technology it is in principle possible to use your electric car as a home battery. To do this, you need a suitable car (such as a Nissan Leaf, Hyundai Ioniq 5 or KIA EV6) as well as a bi-directional charging station.

In practice, this technology is still under development, and regulations and certification also play an important role. Many parties, including car manufacturers and grid operators, are working hard on this. SunCharged follows these developments closely and will certainly facilitate V2H solutions in the future, as soon as this is technically and legally feasible.

Question 19

Is my grid operator involved in the installation?

Accepted Answer

For a standard home battery installation, your grid operator does not need to be directly involved.
Only when feeding back above 3x25A (17.3 kW) do you need to report this to your grid operator, such as Liander or Enexis.
At SunCharged, we take care of all technical aspects of the installation and assist you if necessary with communication to your grid operator.
We ensure that your system complies with all grid codes and safety regulations.

Question 20

Is a home battery good for the environment?

Accepted Answer

A home battery contributes positively to the environment by increasing your self-consumption of solar energy (up to 80%) and reducing the load on the electricity grid.
This reduces the need for fossil fuel backup power plants during peak moments.
Although battery production is energy-intensive, this 'ecological debt' is more than made up for during the battery's lifetime.
At SunCharged, we only work with manufacturers that use sustainable production processes and offer good recycling programs for used batteries.

Question 21

What do solar panels cost on average?

Accepted Answer

In 2025, an average system of 10 solar panels (about 3,700 Wp) will cost between €4,500 and €7,500, including installation and inverter.
The exact price depends on several factors, such as the choice between micro inverters or a string inverter, and the complexity of the installation.

At SunCharged we work exclusively with high-quality materials and Tier 1 solar panels from reliable manufacturers. This ensures quality and a system that suits your home and needs. In addition, you benefit from the 0% VAT rate on both the panels and the installation.

Question 22

How many solar panels do I need for my household?

Accepted Answer

For an average Dutch household with an annual consumption of 3,000 kWh, approximately 8-10 solar panels (370-400 Wp per panel) are ideal.
The exact calculation depends on your specific energy consumption, roof orientation, tilt angle, and any potential shade.
At SunCharged, we make a personal analysis of your situation and energy consumption to determine the optimal number of panels. We take into account future developments such as electric driving or a heat pump.

Question 23

How long do solar panels last?

Accepted Answer

Modern solar panels last an average of 25 to 30 years and often deliver 80-85% of their original power after 25 years. The inverter usually has a shorter lifespan of 10 to 15 years and may need to be replaced in the interim.

At SunCharged, we only select solar panels with excellent warranty conditions: at least a 12-year product warranty and a 25-year power warranty. So you invest in a system that performs reliably for a long time and provides returns for years.

Question 24

How quickly will I recoup my investment in solar panels?

Accepted Answer

Solar panels remain a wise and sustainable investment. You generate your own energy, reduce your energy bill and are less dependent on fluctuating energy prices.

The payback period is currently often between 5 and 7 years, but this depends on factors such as your energy consumption, roof orientation and current energy prices. Thanks to the net-metering scheme, the return is still favorable now; after phasing out, you can further optimize your own consumption with a home battery.

Question 25

Can I still make use of net metering in 2025?

Accepted Answer

Yes, in 2025 you can still fully utilize the net metering scheme.
This allows you to offset the electricity you feed back into the grid one-to-one with the electricity you consume.
From 2027, this scheme will be gradually phased out, making a home battery more attractive. At SunCharged, we're happy to advise you on the best timing for your investment in solar panels and possibly a home battery, taking into account this changing regulation.

Question 26

What happens if I generate more electricity than I use?

Accepted Answer

When you generate more electricity than you use, the surplus is fed back into the electricity grid.
Until 2027, you'll still benefit from the full net metering scheme, where this feed-in is offset one-to-one with your consumption.
After 2027, you'll receive a feed-in tariff that is lower than the supply rate. A home battery then becomes more interesting to increase your self-consumption. At SunCharged, we can advise you on the optimal balance between solar panels and battery storage for your specific situation.

Question 27

Is there a subsidy for solar panels in the Netherlands?

Accepted Answer

Since 2023, the 0% VAT rate applies to both the panels and the installation, which provides a direct saving of 21%.
There is no longer a national purchase subsidy, but some municipalities still offer local subsidies or sustainability loans with low interest rates.
At SunCharged, we closely monitor all subsidy opportunities and inform you about schemes in your municipality. We can also help you apply for any subsidies or financing options.

Question 28

Do I need a permit for solar panels?

Accepted Answer

In most cases, you don't need a permit for solar panels on a sloped or flat roof.
Exceptions are monumental buildings, protected city views, or when the panels protrude far.
For apartments, permission from the VvE (homeowners association) is often required. At SunCharged, we always check the local regulations for your specific situation and help you, if necessary, with obtaining the right permits or permissions, so you don't have to worry about that.

Question 29

How much space do solar panels take up on my roof?

Accepted Answer

A standard solar panel takes up about 1.7 m² of roof area (approx. 1.7 x 1.0 meters).
For a system of 10 panels, you therefore need about 17 m² of available roof area.
At SunCharged, we use advanced design software to accurately map your roof. We optimize the layout taking into account any obstacles such as skylights or chimneys, and if necessary, choose panels with a higher power output to maximize the use of the available space.

Question 30

Which type of solar panel is the best?

Accepted Answer

Monocrystalline solar panels offer the highest efficiency (up to 22%) and are ideal if your roof space is limited.
They are slightly more expensive but deliver more power per square meter.
Polycrystalline panels are cheaper but slightly less efficient (15-17%). For most households, we recommend monocrystalline panels because of their better performance and aesthetics. At SunCharged, we only select panels from A-brands with excellent warranty terms and reliable performance, so you can enjoy your solar energy worry-free for years to come.

Question 31

What is the yield of solar panels in the Netherlands?

Accepted Answer

In the Netherlands, solar panels produce an average of 850-1,000 kWh per kWp (kilowatt peak) installed capacity per year.
A system of 10 panels (3.7 kWp) therefore produces approximately 3,150-3,700 kWh per year.
The exact yield depends on your roof orientation (south is optimal), tilt angle (30-40 degrees is ideal) and any potential shade. At SunCharged, we make an accurate yield calculation for your specific situation using professional simulation software, so you know exactly what to expect.

Question 32

Do solar panels also work when it's cloudy?

Accepted Answer

Yes, solar panels also work in cloudy weather, although the yield is lower.
Modern panels can utilize diffuse light well and still produce 20-30% of their maximum capacity on cloudy days.
In the Netherlands, about 60% of the annual yield is realized in the summer months (April-September) and 40% in the winter months. At SunCharged, we take into account the Dutch climate and seasonal patterns in our calculations, so you get a realistic estimate of the annual yield.

Question 33

What maintenance do solar panels require?

Accepted Answer

Solar panels are virtually maintenance-free.
Rain washes away most of the dirt, especially on roofs with a slope of 15 degrees or more.
On flat roofs or in areas with high pollution, an annual cleaning with demineralized water can increase the yield by 5-10%. Also, regularly check if your inverter is still working properly via the monitoring app. At SunCharged, we offer optional maintenance contracts where we periodically inspect and clean your system if necessary, so you're always assured of optimal performance.

Question 34

What does an inverter do and how long does it last?

Accepted Answer

An inverter converts the direct current (DC) from your solar panels into usable alternating current (AC) for your home.
This essential component lasts an average of 10-15 years, shorter than the panels themselves (25-30 years).
A quality inverter costs between €800 and €1,500, depending on the power. At SunCharged, we only install inverters from top brands like SMA, Fronius or SolarEdge, with extended warranty (standard 5-10 years, optionally extendable). We also advise you on smart monitoring options so you can always track the performance of your system.

Question 35

Can I store my generated electricity?

Accepted Answer

Yes, you can store your self-generated solar power in a home battery.
This becomes increasingly attractive as the net metering scheme is phased out (from 2027).
With a battery, you increase your self-consumption from 30% to 60-80% and are less dependent on the electricity grid. At SunCharged, we offer integrated solutions where solar panels and home batteries are perfectly matched. We can also make your system 'battery-ready', so you can easily add a battery later when it becomes financially more attractive.

Question 36

Does my meter box need to be adjusted for solar panels?

Accepted Answer

In many cases, an adjustment to the meter box is necessary for solar panels.
You need a free group for the inverter and a smart meter that can record feed-in.
For larger systems (>5 kWp), a heavier connection may be required. At SunCharged, we assess your meter box in advance and advise on any necessary adjustments. If necessary, we also arrange the installation of a smart meter through your network operator and ensure that everything is installed safely and according to the latest NEN standards.

Question 37

What if my roof doesn't face south?

Accepted Answer

A south-facing roof is optimal, but solar panels on east- or west-facing roofs are still very profitable with only 10-20% less yield.
East-facing panels produce more in the morning, west-facing more in the afternoon and evening.
This spread can even be beneficial for your own consumption. At SunCharged, we make an accurate yield calculation for your specific roof orientation and advise on the optimal layout. With modern, efficient panels, almost any roof orientation (except north) is suitable for a profitable solar panel system.

Question 38

Can I also install solar panels on a flat roof?

Accepted Answer

Absolutely! Flat roofs are excellent for solar panels.
We then place the panels on lightweight mounting systems at an optimal angle (usually 10-15 degrees) and orientation (preferably south).
The great advantage of a flat roof is that we can position the panels perfectly for maximum yield, regardless of the orientation of your home. At SunCharged, we use special ballast systems that do not damage your roof covering and provide sufficient stability, even in strong winds.

Question 39

What about the warranty on solar panels?

Accepted Answer

At SunCharged, we only select solar panels with excellent warranty conditions: at least 12 years product warranty against manufacturing defects and 25 years power warranty (at least 80% of the original power after 25 years).
For the inverter, you get 5-10 years warranty, depending on the brand.
In addition, we offer 10 years installation warranty on our work. All these warranties are fully documented and transferable when selling your home. This ensures you have a worry-free investment for the long term.

Question 40

What is a micro-inverter and when is it useful?

Accepted Answer

A micro-inverter is a small inverter that is placed under each individual solar panel, instead of one central inverter for the entire system.
This is particularly beneficial in shade situations or different roof orientations, as each panel can function independently.
They also offer detailed monitoring per panel and a longer lifespan (up to 25 years). Although they are slightly more expensive than a central inverter, they can increase the total yield by 5-25% in suboptimal situations. At SunCharged, we advise on the most suitable type of inverter based on your specific roof situation.

Question 41

Can I take my solar panels with me when I move?

Accepted Answer

Technically, it is possible to take solar panels with you when you move, but in practice, this is often not the most practical or cost-effective option.
The de-installation, transport, and re-installation cost about 50% of a new system.
Moreover, solar panels increase the value of your home by an average of 80% of the original investment. At SunCharged, we usually advise leaving the panels behind and taking the value into account in the selling price. We can, however, ensure a professional transfer with all documentation and explanation for the new owner.

Question 42

Does shade have a significant impact on the yield?

Accepted Answer

Yes, shade can have a significant impact on the yield of solar panels.
Even partial shade on one panel can reduce the yield of an entire string (series-connected panels) by 25-40%.
At SunCharged, we perform a detailed shade analysis and offer solutions such as power optimizers or micro-inverters that minimize the effect of shade. These technologies ensure that each panel functions independently, limiting the impact of shade to only the shaded panel. We always design your system with potential shade situations in mind.

Question 43

How do I choose a reliable installer?

Accepted Answer

When choosing an installer, it's essential to look for certifications like Zonnekeur or InstallQ, which guarantee that the installer meets strict quality requirements.
Also, check online reviews, ask for reference projects, and compare multiple quotes.
Don't just focus on price, but also on the quality of the materials used, warranty conditions, and after-sales service. At SunCharged, we only work with certified technicians, offer extended warranties, and are known for our personal service and support, even long after installation.

Question 44

What happens during a power outage – do my solar panels still work?

Accepted Answer

Standard solar panel systems automatically shut off during a power outage.
This is a safety measure to prevent electricity from being fed back into the grid while network operators are working on repairs.
If you also want to use your solar panels during a power outage, we can equip your system with a special backup provision or a home battery with island operation. At SunCharged, we're happy to advise on the various options to increase your energy security, so you also have access to your self-generated energy during power outages.

Question 45

How does monitoring of my solar panels work?

Accepted Answer

Modern solar panel systems come with advanced monitoring via a smartphone app or web portal.
This allows you to see in real-time how much energy your system produces, what your historical yield is, and in some cases, how much you consume.
The monitoring also alerts you to any malfunctions or underperformance. At SunCharged, we install a standard monitoring system that gives you easy insight into the performance of your solar panels. We can also remotely monitor this data and proactively contact you if we detect any deviations, so you're always assured of optimal performance.

Question 46

What does a home charging station cost on average?

Accepted Answer

A quality home charging station in 2025 will cost on average between €750 and €1,750, excluding installation. The final price depends on the type of charging station and the desired features. Smart charging posts with options such as dynamic charging, consumption monitoring and app control are at the upper end of this price range.

Installation costs vary by situation. Standard installation is often relatively simple, but additional excavation or meter box modifications can increase the total amount.

At SunCharged, we are happy to advise you on the charging solution that fits your car, energy contract and future plans. Of course, all our charging stations meet the latest safety standards and are ready for the future.

Question 47

How long does it take to fully charge my car at home?

Accepted Answer

The charging time depends on three factors: the capacity of your car battery, the maximum charging power of your car, and the power of your charging station.
With a standard 11 kW charging station, you can fully charge an average electric car (60 kWh battery) in 4-6 hours.
Smaller cars like a Renault Zoe charge in 2-3 hours, while larger SUVs with a 100 kWh battery need 8-9 hours.

Question 48

What is the difference between single-phase and three-phase charging?

Accepted Answer

With single-phase charging, you use one of the three available phases of your electricity connection, which yields a maximum charging power of 3.7 kW (16A) or 7.4 kW (32A).
With three-phase charging, all three phases are used, allowing you to charge at 11 kW (16A) or even 22 kW (32A).
Three-phase charging is therefore significantly faster, but requires that both your car and your grid connection support three-phase charging.

Question 49

Does my fuse box need to be adjusted for a charging station?

Accepted Answer

In many cases, an adjustment to the fuse box is necessary for a charging station.
For an 11 kW charging station, you need a three-phase connection (3x25A) and a free group in your fuse box.
For older homes, a reinforcement of the connection or expansion of the fuse box may be necessary.

Question 50

Can I get a subsidy for a charging station?

Accepted Answer

In 2025, there are various subsidy options for charging stations in the Netherlands.
Some municipalities offer local subsidies for home charging stations, and there are also provincial schemes available.
For business users, there is the MIA/VAMIL scheme, which makes up to 45% of the investment costs tax deductible.

Question 51

What is smart charging and why is it useful?

Accepted Answer

Smart charging means that your charging station intelligently communicates with your car, energy system, and/or energy supplier to optimize the charging process.
The benefits are numerous: you can automatically charge at times when the electricity price is low (with a dynamic contract), adjust the charging power to the available capacity in your home (load balancing), or align charging with the yield of your solar panels.
This not only saves costs but also contributes to a stable electricity grid.

Question 52

Can I connect my solar panels to my charging station?

Accepted Answer

It's not that your solar panels are directly connected to your charging station, but a smart charging station does allow you to harness your solar energy directly. Such a charging station automatically adjusts the charging capacity to the output of your solar panels. There are also charging stations that charge precisely when the electricity price is low - which often coincides with sunny moments. Simple charging stations do not take this into account. What fits best depends on your needs and how smart you want to control the charging process. We would be happy to advise you on this.

Question 53

What does it cost to charge an electric car at home per kWh?

Accepted Answer

The cost of charging an electric car at home is directly linked to your electricity rate.
In 2025, this averages between €0.25 and €0.40 per kWh, depending on your energy contract.
With a dynamic energy contract, prices can fluctuate between €0.10 and €0.50 per kWh, depending on supply and demand.

Question 54

Can I share my charging station with neighbors or family?

Accepted Answer

Yes, sharing your charging station with neighbors, family, or friends is certainly possible and can reduce the cost per person.
Modern smart charging stations offer various solutions for this.
You can opt for a charging station with multiple connections or an authentication system via charging cards or apps.

Question 55

What is load balancing for charging stations?

Accepted Answer

Load balancing (or dynamic charging) is a smart feature where your charging station continuously monitors the power consumption in your home and automatically adjusts the charging power to prevent overload.
When other appliances consume a lot of power, the charging station temporarily reduces its power.
As soon as capacity becomes available again, the charging station increases the charging power again.

Question 56

Is there a difference between a charging station and a wallbox?

Accepted Answer

The terms 'charging station' and 'wallbox' are often used interchangeably, but technically there is a small difference.
A 'charging station' (or charging post) is a standalone post, often used in public spaces or driveways.
A 'wallbox' is a more compact charger mounted on the wall, ideal for garages or carports.

Question 57

What does bidirectional charging mean (V2H or V2G)?

Accepted Answer

Bidirectional charging means that electricity can flow in two directions: from the grid to the car (normal charging) and from the car back to the home (Vehicle-to-Home, V2H) or the grid (Vehicle-to-Grid, V2G).
With V2H, you can use your car battery as a home battery during peak times or power outages.
With V2G, you can even earn money by feeding power back to the grid during high prices.

Question 58

How much power should my charging station have?

Accepted Answer

The ideal charging power depends on your car, grid connection and charging needs. Most electric cars support AC charging up to 11 kW (3-phase).
An 11 kW charging station is therefore often the best choice for your home, provided you have a 3-phase connection - an average car will then fully charge within 6-10 hours, even if the battery is flat.

Question 59

What does monitoring of the charging station or solar panels involve after installation?

Accepted Answer

Monitoring means using an app or portal to track in real time how much power you are generating, consuming or charging. This gives you insight into performance, you quickly spot possible malfunctions and you manage your energy consumption smarter. At SunCharged, we often actively watch your system to resolve malfunctions or install updates. We can also perform an analysis to determine when and which battery capacity best suits your energy needs.

Question 60

What does optimizing energy usage mean?

Accepted Answer

Optimization means using smart systems to consume or store energy at the best moment—for example, charging when the sun is shining or electricity prices are low, saving you money and reducing grid pressure.

Question 61

What does trading on the EPEX market mean?

Accepted Answer

Trading on the EPEX market means being smart about your energy consumption and storage: you use power or charge your battery when the price is low, and you consume less or feed back to the grid when the price is high. This works in conjunction with a dynamic energy tariff, where the price of power changes every hour. With a smart energy system, this happens automatically. This provides financial benefits and helps keep the energy grid in balance.

Question 62

What exactly is the Bliq Energy Manager?

Accepted Answer

The Bliq Energy Manager is a smart device that gives insight into your energy use, generation, and charging behavior. It controls devices like your charger or battery based on solar production and dynamic pricing to lower your energy costs.

Question 63

What does trading in the imbalance market mean?

Accepted Answer

Trading in the imbalance market means helping to keep the power grid in balance by being flexible with your energy consumption or storage. The power grid must be in balance at all times: there may not be too much or too little power.

If, for example, you temporarily take off less or more power or feed it back at a time when the grid needs it, you can receive compensation for this. With smart software and a suitable energy system, this happens automatically and you can therefore earn money by balancing the grid.

Question 64

What is an energy management system (EMS)?

An EMS is a smart power plant that controls your energy consumption, energy production such as that from solar panels, and energy storage such as a home battery. Ideally, you also want to be able to use this to control as many household smart appliances as possible. The EMS ensures that everything is done as efficiently and inexpensively as possible, often fully automatically.
