38.5% less volume compared to Venus 2.0
The Venus Gen 3.0 is our most elegant design to date – with slimmer dimensions, softer edges, and 38.5% less volume than the previous generation, it integrates seamlessly into any living space.
Up to 2500 W AC input and output power
Enough power to run all your essential household appliances simultaneously – from the microwave to the refrigerator. Venus Gen 3.0 delivers up to 2500 W of continuous grid power – reliable and stable. *The standard output power is 800 W. An upgrade to 2500 W may require approval from the grid operator or local authorities.
Expandable to 7.5 kW / 15.36 kWh in single-phase operation
Venus Gen 3.0 supports up to three devices in a single-phase configuration – for scalable performance and storage capacity of up to 7.5 kW and 15.36 kWh. Designed for maximum flexibility and real requirements. *The expansion depends on the capacity of your electrical house connection. Please consult a certified electrical specialist before installation.
100% compatible with existing PV systems
Venus Gen 3.0 was developed to seamlessly work with your existing grid-tied solar system – without replacing the inverter or making changes to the system. Just plug in and store more solar energy.
Up to 2500 W reliable emergency power supply
Venus Gen 3.0 features a dedicated emergency power connection (Backup) that provides up to 2500 W of power during outages. Reliably power essential devices like lamps, routers, or refrigerators – even when the power grid fails.
Multiple modes for diverse needs
With the MARSTEK app, you can effortlessly switch between AI optimization, self-consumption, and manual modes. Venus Gen 3.0 adapts to your energy style – whether you desire complete automation, intelligent response, or manual precision.
Intelligent energy begins with AI and dynamic rates
The AI mode of the Venus Gen 3.0 automatically plans your charging times based on the real-time electricity prices in your region from platforms like Nord Pool, Tibber, and Octopus Energy.
It learns your energy consumption patterns, analyzes battery status and weather forecasts, and continuously adjusts the timing and amount of charging — helping you to reduce costs and maximize savings, all without effort.
Null feed-in to the grid thanks to smart meter
By integrating a real-time smart meter and adaptive control, Venus Gen 3.0 ensures that no excess solar energy is fed into the grid. Ideal for regions with feed-in restrictions or limited feed-in tariffs.
Annual savings of €1,310
Venus Gen 3.0 helps you save up to €1,310 per year through AI-supported control and real-time electricity prices.
