The Marstek VENUS A is a so-called “all-in-one” AC-coupled energy storage system (balcony/home battery) with integrated inverter and battery.
It is designed to store solar energy from a PV system, support critical consumption during power outages, and optimize energy use with smart control.


Feature Value / explanation
Design All-in-one (battery + inverter integrated)
MPPT inputs 4 independent MPPT channels (so you can connect multiple solar panels or strings)
Maximum PV input Up to ~ 2.4 kW solar panel power
Basic battery capacity (starting) 2.12 kWh (usable capacity)
Expandability / modular Can be expanded up to a maximum of 12.72 kWh by connecting multiple modules (or units)
AC power (on-grid / auxiliary power) 1.2 kW continuous, with peak power up to ~ 1.44 kW (for shorter load)
Switching delay (EPS / backup) < 15 ms switchover in case of mains failure (so that important equipment can continue to operate briefly)
Battery cell type / lifespan LFP (lithium iron phosphate) cells, > 6000 charge/discharge cycles, designed for 15 years of use
Protection / environment IP65 housing (dust and splash resistant)
Temperature range Operation possible in temperature range from ~ –20 °C to +55 °C (or similar according to specifications)
Communication & integration Support for WiFi, Ethernet, Bluetooth, possible anti-feed-in function, smart meter connection
Price indication at launch Approximately €499 for the base unit (2.12 kWh) in Germany at launch


  • Increase self-consumption
    The VENUS A can store excess solar energy so you can use it later instead of feeding it back into the grid.

  • Backup / emergency power
    In the event of a power failure, the unit can continue to supply essential loads (within the power limits) thanks to the < 15 ms changeover.

  • Extensibility
    Thanks to its modular nature, you can start with a smaller capacity and expand later as your needs grow.

  • Smart control
    As with many modern storage solutions, the VENUS A is expected to use smart algorithms (AI) to optimize charge/discharge timing based on consumption, solar yield and electricity prices.

  • Compatibility with existing PV installations
    Because it is an inverter + battery in one system, it can be easier to fit into balcony or smaller PV projects where space or modularity is desired.
