  • No signal loss in complex networks

Up to 2500W on-grid power

    Connect up to three units in parallel on one phase and increase your power to 7.5 kW with a storage capacity of 15.36 kWh. The ideal solution for growing energy needs.

    Fully compatible with existing solar panels

    The Marstek Venus E Gen 3.0 works seamlessly with your current PV installation. You don't need to replace anything. Just plug it in and start storing energy.

    Emergency power up to 2500W during power outages

    In the event of a grid failure, the battery provides up to 2500W of backup power. This keeps essential appliances like lighting, routers, and refrigerators running.

    In combination with the optional Marstek Smart Box, full-home backup is possible for both single-phase and three-phase systems.

    Smart charging via AI and dynamic tariffs

    The AI mode automatically schedules the ideal charging time based on:

    • Electricity prices from providers such as Nord Pool, Tibber, and Octopus Energy
    • Your consumption pattern
    • Weather forecasts and battery status

    Real-time energy management via Marstek App

    Effortlessly choose between:

    • AI optimization
    • Self-consumption
    • Manual settings

    You can adjust your strategy with one click via the intuitive Marstek app.

    Zero feed-in with limited injection

    Thanks to smart meter integration, you automatically prevent excess solar energy from being fed back into the grid. Useful in regions with feed-in limitations or low feed-in tariffs.

    General note: Marstek Support
