Protect electric battery storage systems

Battery storage systems store the excess energy produced by PV systems and feed it back into the grid when required. This counterbalances fluctuations and peak loads in the power supply network.

Surges, direct lightning strikes put your battery storage system at risk.

Lightning discharge jeopardises the sensitive electronics required for the process of loading and discharging. The surges which occur often exceed the dielectric strength of the electronic components installed many times over. Network-related voltage peaks can also damage electronic parts.

In fact, just ONE defective component in the chain could be enough to cause the whole battery storage system to malfunction. The operator then has to resort to other systems in order to fulfil  his contractual obligations. A very costly process for him.

Minimise expensive maintenance and repair work. Safeguard the availability of your storage system. With a customised lightning and surge protection concept.

Product recommendation
