Marstek Venus X all-in-one AC-coupled storage system 10kWh 6kW LiFePO4
The Marstek Venus X is an all-in-one residential storage system that combines 10kWh of LiFePO4 battery and a 3.6kW / 6kW bidirectional inverter in a single AC-coupled cabinet. It integrates existing solar arrays of up to 7.5kW without changing their inverter and offers two installation modes: plug & play for a fast setup, or WireLite hardwiring to unlock full power for heavy loads.
It is the answer for high-consumption homes and small businesses that want maximum self-consumption, peak shaving and continuity of supply: the backup port delivers 6kW continuous with 12kW surge and switchover under 10 ms. With the SmartBox, up to three units run in parallel for as much as 60kWh. Anti feed-in responds in 3 seconds, cells last over 10,000 cycles, and the unit is IP65 rated, works from -25 to 55 °C and stays below 30 dB.
