en.Wedoany.com Reported - MOVA LumeGret has launched a modular energy storage system, the S4800, designed for apartment dwellers, suburban single-family homes, and electric vehicle users. It aims to address new demands arising from Europe's tightening net metering policies, fluctuating electricity prices, and the predominantly apartment-based urban housing structure.
The system has a photovoltaic input power of 4800 watts, sufficient to support eight to ten 450-watt solar panels on a typical balcony or small rooftop array. The peak MPPT efficiency is rated at 99.8%. The base battery configuration starts at 3 kWh or 5 kWh and can be expanded to 15 kWh or 25 kWh via stackable expansion modules. The grid-tied AC output power ranges from 800 watts to 3000 watts; off-grid capacity is 3600 watts. AC charging power is rated at 3000 watts, allowing the battery to charge from the grid during low nighttime electricity price periods. The electric vehicle charging port supports up to 6.6 kW, adding approximately 40 to 55 kilometers of range per charge under optimal solar conditions, sufficient to meet the weekday commuting needs of households with an average daily travel distance of less than 50 kilometers, primarily using locally generated power. The system has an IP65 protection rating, supporting outdoor installations such as on balconies and in gardens. The base S4800 requires no wall drilling or dedicated distribution box, and installation takes about 30 minutes.
The system's intelligent layer is as critical as its hardware. The S4800 retrieves dynamic pricing data from over 860 energy suppliers in major European markets to optimize charging and discharging schedules based on real-time electricity prices: discharging is concentrated during peak price periods, while charging prioritizes low-price periods. The FluxCharge function adjusts the electric vehicle charging power based on real-time photovoltaic generation to maximize self-consumption. The system supports Shelly-based smart meter integration, allowing the ecosystem to be further expanded based on market demand.
The S4800 is positioned between the A4000, designed for whole-home energy storage, and the A2000, intended for safe balcony systems. The A4000 can be expanded to 20 kWh, suitable for high-energy-consumption households or rooftop solar arrays. The A2000 is specifically designed for compact balcony railing installations. The S4800 bridges these two application scenarios by adding electric vehicle charging and dynamic pricing intelligence.
Roger Shen, President of MOVA LumeGret, stated that future residential energy systems depend not only on storage capacity but also on the ability to intelligently manage and utilize energy. The S4800 aims to provide channel partners with a broader range of customer application scenarios and deliver greater long-term value through a single installation.
The S4800 has obtained certifications covering European safety, electromagnetic compatibility, battery, and grid standards, with initial certifications completed in Germany, France, and the Netherlands. Mass production will begin at the end of June, with commercial launch targeted for the fourth quarter of 2026. It is currently sold through e-commerce and installer networks, with plans to expand to major home improvement retail channels such as OBI and Bauhaus in the second half of 2026. The product will make its public debut at booth C1.556.
