Marstek Venus E Mini plug-in AC battery storage system 2kWh 1.5kW LiFePO4 wall-mounted
The Marstek Venus E Mini is the thinnest plug-in storage system in the range: only 105 mm thick and 22 kg for 2kWh of capacity and a 1.5kW bidirectional inverter. It mounts on the wall and AC-couples to the household grid in minutes, with no DC-side work and no need to replace the existing solar inverter, with which it stays 100% compatible.
It is made for balconies, garages and flats where space is tight, and for anyone who wants to start storing with a small but expandable size: two units reach 4kWh and 3kW with the single-phase SmartBox. The backup socket delivers 1.5kVA continuous with EPS switchover in under 15 ms, the LiFePO4 cells exceed 10,000 cycles and the built-in BMS provides six layers of protection. IP65 rated and operating from -20 to +60 °C.
