A home battery, also known as a home accumulator, is a system that stores electrical energy for future use in a household. It is often combined with solar panels, but can also be charged via the regular power grid. This technology makes it possible to efficiently use generated energy, even when demand is higher or no sunlight is available.

Main features of a home battery

1. Storage of solar energy:
   A home battery captures surplus energy generated by solar panels during the day. This energy can be used later, for example, in the evening hours.

2. Backup power supply:
   During a power outage, a home battery can supply power to essential devices, such as lighting, refrigerators, and medical equipment.

3. Optimization of energy costs:
   By storing energy during off-peak hours (when prices are lower) and using it during peak hours, households can reduce their energy bills.

4. Grid independence:
   A home battery offers households more autonomy as it makes them less reliant on the power grid.

Specifications of a home battery

• Capacity:
  The capacity is measured in kilowatt-hours (kWh) and can range from a few kWh to dozens of kWh, depending on the model.

• Lifespan:
  Modern home batteries typically last 10 to 20 years, depending on the type and usage.

• Charge time:
  Completely charging a home battery can take a few hours to a day, depending on the battery capacity and energy source.

• Battery types:
  Most home batteries use lithium-ion technology, although there are also lead-acid and other types available.

Frequently Asked Questions

1. Is a home battery only useful with solar panels?
   No, a home battery can also be used without solar panels by charging it via the power grid.

2. Can a home battery feed energy back to the grid?
   Yes, some models offer this capability. As a result, surplus energy can be fed back, which can provide financial benefits in some regions.

3. How much does a home battery cost?
   The costs vary greatly, but usually range between €5,000 and €15,000, including installation. Subsidies can reduce these costs.

4. What devices can be powered by a home battery?
   Depending on the capacity, devices such as lighting, refrigerators, computers, security systems, and even heating systems can be powered.

5. How is a home battery maintained?
   Most modern systems require minimal maintenance, but regular checking of performance and the storage system is recommended.

How to integrate a home battery into your household?

Installing a home battery not only offers financial benefits, but also contributes to more sustainable energy consumption.
