The Marstek Venus E 3.0 is a modern home storage solution with AC coupling that features compact dimensions, intelligent energy management and strong backup functions. It offers a storage capacity of approx. 5.12 kWh LiFePO₄ battery technology with over 6,000 charging cycles, which promises a long service life. Typical features include flexibility in use (input and output power), scalability, and robust construction for indoor and outdoor use.

More compact & lighter design
Gen 3.0 is approximately 38.5% smaller and 7.4% lighter than the previous version, making installation easier - inside and out.

High performance & backup capability
With 2.5 kW AC input and output power, the unit reliably supplies essential household areas. It also offers fast emergency power supply in the event of failures (backup) with only a short switchover time (~15 ms) to supply critical loads.

Smart metering & 100% self-consumption
The Venus E 3.0 can be seamlessly integrated into existing PV systems, supports anti-feed-in (avoiding feed-in) and uses intelligent meters and real-time measurement to make optimal use of excess solar power.

Robust construction & protection class
The unit is weatherproof (IP65), temperature tolerant and designed for use in demanding environments. The outer housing made of die-cast aluminum ensures stability and durability.

Scalability & communication options
It can be expanded to multiple units (e.g. up to 3 per phase) to increase power and capacity. Interfaces such as LAN, RS485, WiFi & Bluetooth are also supported, as well as open protocols for integration into home management systems.

Efficiency & Lifespan
Battery technology with over 6,000 cycles at a high usage rate, high efficiency and 10-year guarantee make the system economical and reliable in the long term.
