Marstek Venus E 3.0 plug-in AC battery storage system 5.12kWh 2.5kW LiFePO4

The Marstek Venus E 3.0 is a 5.12kWh plug-in AC storage system for homes that already have solar and want to keep the energy they generate without rebuilding the installation. AC coupling needs a single cable: it plugs into the household grid like any appliance and remains 100% compatible with any existing inverter. The third generation cuts volume by 38.5%, uses a die-cast aluminium housing and adds dual RJ45 ports for RS485 and Ethernet.

It suits families and small businesses that want to eliminate grid feed-in, take advantage of dynamic tariffs and keep a backup socket of up to 2.5kVA available during outages. AI mode schedules charging against real-time energy prices, while the LiFePO4 cells deliver over 6,000 cycles at 90% depth of discharge. It works down to -20 °C, is IP65 rated and stays below 30 dB.

Key features

5.12kWh always on hand100Ah LiFePO4 battery at 51.2V with 90% depth of discharge: more than 4.6kWh usable per cycle, for over 6,000 cycles.
Installed in minutesAC coupling needs one cable with a household plug: no DC-side work and no need to replace the existing inverter.
Backup up to 2.5kVAThe dedicated backup socket powers lights, routers and the fridge during outages, with 3.5kVA peak for 10 seconds.
Stable communication and open APIDual RJ45 port with RS485 and Ethernet, plus Wi-Fi, Bluetooth and an open API for Home Assistant and ioBroker.
