Marstek Venus A all-in-one storage system 2.12kWh LiFePO4 with 4 MPPT
The Marstek Venus A is an all-in-one storage system for balcony solar: a single body holds a 2.12kWh LiFePO4 battery, an integrated microinverter and four independent MPPTs with 2400W of PV input power. No separate inverter is needed: panels connect directly with MC4 connectors, and the energy is stored and returned as AC to the household grid.
It suits anyone starting from a small array who wants to grow over time up to 12.72kWh by adding battery modules. The system takes advantage of dynamic tariffs by charging when prices are low, runs zero grid feed-in with a smart meter and keeps essential loads alive through the Schuko backup socket. Over 6,000 cycles, 90% depth of discharge, IP65 and operation down to -20 °C.
Key features
Four MPPTs and 2400W inputFour independent trackers with a 16-60V range harvest energy even from strings facing different directions, with MC4 connectors.
Everything in one bodyBattery, microinverter and energy management are integrated: no separate components and far simpler installation.
Expandable to 12.72kWhStart at 2.12kWh and add battery modules as consumption grows, without replacing the system.
Backup on a Schuko socket1.2kW continuous and 1.44kW peak to power essential devices during an outage.
