Sunny Boy Storage - 2500W Inverter/Charger

Product discontinued


High voltage battery inverter-charger

The Sunny Boy Storage is a grid connected battery inverter for high-voltage batteries (e.g. Tesla Powerwall, LG Chem High Voltage). Featuring a charge and discharge power of 2500W, it is suited to coping with the electricity demand of a typical household.

The SB Storage is the first Powerwall compatible inverter that can be used to retrofit a solar grid connect system with a high voltage battery - without changing the existing inverter. The size, brand and age of the installed solar system does not matter as long as it is on a single phase grid connection.

The inverter will supply or supplement the household's energy consumption with up to 2.5kW.
