MARSTEK Showcases New VENUS Energy Storage Systems at Solar Solutions Düsseldorf 2025

A key highlight is MARSTEKVENUS G, a stackable 5kW AC-coupled ESS with 500V V-Boost technology. It combines a bidirectional inverter with 10kW peak power, ultra-fast backup switching, and modular capacity expansion from 5kWh to 30kWh. With 7.5kW AC PV input, it easily integrates with Enphase, SolarEdge, and other PV systems, while the 7.5kW on-grid input enables fast, low-tariff charging. Designed for easy retrofits, it offers seamless monitoring through a smart app and multiple communication interfaces.
