What Revolty does
Revolty is a French cleantech startup founded in 2024 that refurbishes second-life lithium battery cells into affordable residential solar energy storage systems. The company addresses a dual inefficiency: roughly one million French solar households lose 60% of their self-generated electricity to the grid at unprofitable feed-in tariffs while millions of healthy lithium cells are discarded annually. Its primary customers are homeowners with existing or new photovoltaic installations and RGE-certified solar installer partners across France, with 92 households having placed reservations and three field prototypes deployed since February 2025.
The company's core product is the Revolty Battery, an AC-coupled all-in-one wall-mounted unit combining battery cells, inverter, and backup power in three capacity tiers (5 kWh, 10 kWh, 15 kWh). The technology uses reconditioned second-life lithium cells certified for reuse, paired with proprietary "Revolty Intelligence" software that automates time-of-use optimization, appliance scheduling (heat pumps, water heaters, pool, EV chargers), and off-peak charging. An hour-by-hour seasonal simulation engine leverages RTE, ADEME, EDF consumption profiles and PVGIS solar production data to size battery capacity, claimed to be more accurate than competitors using annual averages. The system is natively compatible with leading inverter brands including Enphase, SMA, Fronius, Huawei, and SolarEdge, with a 10-year warranty and real-time fleet monitoring.
Revolty operates a hybrid B2C/B2B2C go-to-market model. Direct-to-consumer sales are conducted via the company website using a reservation system, with battery delivery planned for Q1 2027 and pricing not publicly disclosed. Distribution is supported through a network of 22+ certified RGE installer partners covering Île-de-France, PACA, Occitanie, and Bretagne regions. The company is pre-revenue, having raised €1 million in seed funding in February 2026 led by Hexa Sprint with Bpifrance participation and additional angel investors including co-founders of Verkor, Murfy, and Electra. Headquarters are at the AGORANOV tech incubator in Paris.
