Renewable energy visitors at EnerGaïa 2025 in Montpellier were introduced to MARSTEK’s newest range of energy storage products, with the company spotlighting expanded capabilities under its VENUS lineup at Hall B3, Booth B29.
Taking center stage was the VENUS G, a next-generation AC-coupled storage platform delivering 5kW of continuous power and 10kW of peak performance.
With 7.5kW AC PV input and compatibility with widely used solar systems, the unit offers homeowners a scalable solution—from 5kWh starter capacity all the way to 30kWh. MARSTEK’s 500V V-Boost technology ensures each battery module operates evenly, while fast backup switching and simplified wiring streamline installation and operation.
Equally notable was MARSTEK’s 7kW single-phase EV charger, developed specifically for the MARS I PLUS ecosystem.
Its adjustable output and load balancing features support safe and efficient home charging, and with IP54 and IK10 construction, it is built for long-term reliability. ISO 15118-ready hardware ensures the charger is prepared for future vehicle-to-home standards.
For compact storage needs, MARSTEK showcased the VENUS D (AC Version), a small-scale, stackable ESS that delivers 2.5kW of power both on-grid and in backup mode.
Each 2.56kWh module can be combined to form a larger 15.36kWh system.
With AI-based forecasting and time-of-use controls, it’s designed to help households cut energy costs and improve the efficiency of self-generated power.
Smart meter integration allows for precise management of energy flow.
Visitors can also explore MARSTEK’s Balcony ESS lineup and additional residential solutions such as VENUS X and MARS I PLUS.
