3kW High-Efficiency Bidirectional Inverter

The Venus E 4.0 features a powerful 3kW bidirectional on-grid inverter, perfectly matching most household loads. It intelligently manages energy flow, significantly increasing self-consumption rate and reducing electricity bills.

3kW Whole-Home Backup with <10ms Seamless Switch

Enjoy uninterrupted power with 3kW continuous backup (peak up to higher loads). The ultra-fast EPS switchover in less than 10ms ensures your critical appliances (refrigerator, lights, router, etc.) continue running smoothly during outages.

With 5kWh usable capacity, the Venus E 4.0 provides longer backup time and greater daily energy shifting capability, perfectly suited for medium to large households looking for true energy independence.

Thanks to the innovative AC-coupled architecture and unique three-in-one interface, you can complete installation in under 10 minutes. Simply hang it on the wall or place it on the floor and plug it in — ready to use instantly.

New Slim Design & Hidden Interface

Featuring a brand-new lightweight and minimalist design, the Venus E 4.0 is thinner and more elegant. The innovative magnetic hidden interface cover completely conceals all cables after installation, delivering a clean and modern look. Supports both wall-mount and floor-standing installation to save space and blend beautifully into any home environment.

Intelligent Display with Millimeter-Wave Radar

Equipped with millimeter-wave radar sensing, the display automatically wakes when a user approaches and turns off when leaving. The redesigned interface provides a more intuitive and clearer display of key information, improving user experience while reducing unnecessary energy consumption for a smarter and more efficient system.

AI-Powered Energy Savings & Revenue Optimization

Powered by advanced AI algorithms, the system learns your household energy usage patterns and continuously analyzes weather conditions and electricity price fluctuations. It intelligently optimizes charging and discharging strategies to minimize energy costs and maximize overall efficiency, delivering up to €1,509 annual savings.

VPP — Your Personal Power Plant on Autopilot

Join the energy revolution. Through Virtual Power Plant integration, your VENUS E 4.0 transforms from a home battery into a revenue-generating grid asset. Automatically trade stored energy during peak demand, earn credits, and get paid for stabilizing the network — while others pay for power, you profit from it.

Intelligent EV Charging Control via MARSTEK VENUS E 4.0

The VENUS 4.0 seamlessly integrates with the MARSTEK portable EV charger, enabling smart and automated vehicle charging management.
The system dynamically schedules EV charging based on electricity prices and solar surplus,
ensuring your vehicle is always charged in the most cost-efficient and energy-optimized way.

User-Friendly Expansion to 9kW / 15kWh Whole-Home Backup

Connect up to three units via SmartBox for fast system expansion and more balanced energy distribution, achieving up to 9kW power and 15kWh capacity to easily support whole-home backup needs.

Monitor energy flow, system status, and historical data in real time through the intuitive Marstek App. Switch between multiple smart modes anytime, anywhere for effortless energy management.

Advanced Battery Management System provides comprehensive protection including over-current, over-voltage, over-temperature, short-circuit, and more, ensuring ultimate safety.

Industrial-Grade LFP Battery with 10,000+ Cycle Life

Utilizing premium 314Ah Lithium Iron Phosphate cells, the Venus E 4.0 offers over 10,000 deep cycles and a design life of more than 15 years, providing long-term reliable performance.
