Energy storage as the key to a self-sufficient power supply

Learn more about how VoltStorage’s safe, powerful and low-cost solar power storage system can be an important step towards self-sufficient power supply.

The desire for self-sufficient power supply

The electric guitar sound from your son’s room, the football evenings in front of the TV or your family’s morning breakfast – many moments at home need power to become reality. To enable these moments on your own with self-produced energy being more autonomous through an independent power supply, is the desire that drives more and more to rely on solar power.
With a photovoltaic system alone, however, one is still a long way from fulfilling this dream. The reason is simple: When we are at home and need electricity, PV systems often produce little to no electricity at all and thus cannot supply the house with energy. Thus one is still dependent from electricity mains in the evening and at night.
Solar Energy Production

Store your solar power for more independence

Use more self-produced solar power in your own home and save on your electricity bill – with the VoltStorage SMART you can use the electricity from your PV system even when the sun is not shining. Because although we do not know how electricity prices will develop in the future: This approach enables you to supply your home with more home-generated electricity and hence makes you more independent of the electricity market.
At the same time you contribute to the reduction of greenhouse gas emissions. For the more solar energy you use, the less dependent you are on the European electricity market, which obtains a large proportion of its electricity from gas, coal and oil-fired power plants that emit greenhouse gases. As such, you are one of the more than 125,000 power storage owners in Germany who can claim: I Power My Home.

Pure sunshine!

Your children are at school, and you and your partner are working. Even before you get home, on a sunny day your solar panels have already generated more electricity than needed. With your energy storage device you can store this power and use it in your household in the evening.
