Venus E Gen 3.0 is designed to work effortlessly with your existing on-grid solar system—no need to replace your current inverter or change your setup. Just plug it in and start storing more of your solar energy.

Up to 2500W of Reliable Backup Power

Venus E Gen 3.0 features a dedicated backup port that delivers up to 2500W during outages. Keep essential appliances—such as lighting, internet routers, or refrigerators—running, ensuring uninterrupted operation when the grid goes down.

Multiple modes to meet diverse needs

With the MARSTEK app, switch effortlessly between AI-Optimization, Self-Consumption and Manual Modes.
Venus E Gen 3.0 adapts to your energy lifestyle—whether you want full automation, intelligent response, or manual precision.

Smarter Energy with AI and Dynamic Tariffs

Venus E Gen 3.0's AI Mode automatically plans your charging based on your region's real-time electricity prices from platforms like Nord Pool, Tibber, and Octopus Energy. It learns your energy usage patterns, analyzes battery level and weather forecasts, and continuously adjusts both when and how much to charge — helping you reduce costs and maximize energy savings without lifting a finger.

Zero Feed-in to Grid enabled by Smart Meter

With real-time smart meter integration and adaptive control, Venus E Gen 3.0 ensures no surplus solar energy is exported to the grid, making it ideal for areas with export restrictions or limited feed-in tariffs.

Annual Savings of €1,310
