Marstek Venus X all-in-one AC-coupled storage system 10 kWh 6 kW LiFePO4
The Marstek Venus X is an all-in-one residential storage system that combines 10 kWh of LiFePO4 battery and a 3.6 kW / 6 kW bidirectional inverter in a single AC-coupled cabinet. It integrates existing solar arrays of up to 7.5 kW 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 6 kW continuous with 12 kW surge and switchover under 10 ms. With the SmartBox, up to three units run in parallel for as much as 60 kWh. 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.
