This highly innovative energy storage systems (ESS) make solar power users independent of energy prices and able to use solar energy they collect at the time they need it. Our intelligent, modular lithium-ion energy storage units save the photovoltaic energy you collect to be at your disposal during night time or when there is low solar radiation. While the sun is shining an inverter allows you to choose between charging up your storage unit or enables your solar power back into the power grid.

Your benefits:

  • Reducing energy costs
  • Lifetime up to 20 years
  • Enviromental technology
  • Emergency power supply in case of power outage
  • 5000 cycles

 Mutli-Level-safety concept

  • Short circuit proof relay and 2nd protection (pyro fuse) for a redundant battery cut-off
  • Overvoltage and low voltage monitoring for each cell string with redundant battery cut-off
  • Temperature monitoring for each cell string and current interrupt device (CID) in each cell
  • Protection against a reboot after deep discharge or any other serious error
  • No insecure parallel connection of cells without current interrupt device (CID) in each cell
  • Active current control as a function of cell voltage and temperature (derating)
  • Double metal housing
