MARSTEK Debuts VENUS E Battery Series at Intersolar Europe 2026

The exhibition, running June 23–25, serves as the global debut for four distinct models. The VENUS E Mini leads the entry-level segment as an ultra-slim, 22kg wall-mounted unit providing 2kWh capacity and 1.5kW bidirectional power. For established solar households, the VENUS E 4.0 offers a 5kWh capacity with AC-coupled architecture, allowing for expansion up to 15kWh via the SmartBox system.

Scaling toward larger residential needs, the VENUS E MAX introduces a 10kWh all-in-one plug-in capacity, which can be scaled to 30kWh. Meanwhile, the VENUS E Pro prioritizes installation efficiency by integrating 3kW high-voltage MPPT and 2kW AC coupling into a single modular design. Supporting 50–500V PV input with a two-wire connection, the Pro model is built for durability, utilizing LFP cells rated for over 10,000 cycles. Following the Munich showcase, the company plans to hold further product workshops in Eindhoven on June 30 to demonstrate these technologies to industry partners.
