Store the energy generated by your solar system in powerful battery storage systems. With a power storage system for your PV system, your stored energy is available to you flexibly, regardless of the time of day and weather conditions. In addition, a PV storage system can protect you during power outages, thus making your household more self-sufficient. Surplus solar power can still be fed into the public grid. When purchasing a storage system, in addition to storage capacity, depth of discharge, system efficiency and service life, you should also make sure that the chosen storage system fits in with the overall system.
