Energy Storage
Energy storage systems increasing self-consumption and energy independence. Perfect complement to PV and wind turbines.
Overview
Energy storage is a key element of modern energy installations. It allows you to store surplus energy from PV or wind and use it when production is lower — in the evening, at night or on cloudy days.
We offer storage from leading manufacturers: Huawei LUNA2000, BYD Battery-Box, Pylontech and more. We select capacity individually based on your energy profile and PV system size.
