Düsseldorf, Germany – MARSTEK, a leading global innovator in energy storage solutions, announced its participation in Solar Solutions Düsseldorf 2025(December 3–4, Messe Düsseldorf, Hall 14, Booths E3 & C8), where it presented its latest next-generation advancements in energy storage and smart charging with the new VENUS products.
Spotlight on Innovation
A key highlight was MARSTEK VENUS G, a stackable 5kW AC-coupled ESS featuring 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 integrates easily with Enphase, SolarEdge, and other PV systems, while the 7.5kW on-grid input enabled fast, low-tariff charging. Designed for easy retrofits, it offers seamless monitoring through a smart app and multiple communication interfaces.
The 11kW three-phase EV AC Charger also played a key role, built for the MARS I PLUS three-phase system. With adaptive load balancing, robust IP54/IK10 protection, and ISO 15118 readiness, it is engineered for safe, flexible, and future-proof EV integration.
Another highlight was MARSTEK VENUS D (AC Version), a plug-in ESS delivering 2.5kW bidirectional on-grid power with peak backup support up to 3.0kW. Its stackable modular design expands from 2.56kWh to 15.36kWh, while AI forecasting and intelligent grid interaction ensure efficient, policy-compliant energy management.
