Battery storage for your home

Why store electricity?

  • Use your own green electricity
  • Back-up against a blackout
  • Smart integration of e-charging point, hat pump, radio-controlled sockets …
  • Independence from rising energy prices
  • Counteracting low feed-in tariffs

Handle your energy flows with a smart storage solution

Electricity consumption in private households peaks in the morning and evening. The reason is that many devices require electricity in both the morning and evening hours (washing machine, dryer, dishwasher, TV, radio, etc.), as people spend the most time at home during these hours. During the day, electricity consumption decreases because most people are out for work.

Let’s check the challenge in renewable energies: The sun emits its strongest radiation during the day around midday. Conversely, this means that the PV system also produces the most electricity at precisely this time. Some electricity can certainly be used, but what about the surplus energy that is produced? This is exactly where the electricity storage system comes into focus. It can temporarily store the excess energy and release it, exactly then, when it is needed. Cap daily load peaks with the storage unit.

Your storage project is planned from 2023? Follow us on our website and social media, we keep you posted about the progress.

Top-Topic Safe against a Blackout 

All BlueSky Energy power storage units provide emergency power in their standard design.

In the event of a power failure, the storage unit switches to emergency power mode in less than 20 milliseconds. A fast switching time is important for sensitive electrical equipment.

With appropriate DC coupling of the PV system, our storage systems are capable of black-starting and work in island mode. In this way, you can bridge longer-lasting power outages in off-grid mode.
