Designed for demanding residential installations, this 48V 100Ah wall-mounted battery with LiFePO4 technology offers an efficient storage solution to maximize self-consumption, maintain backup power in case of outages, and secure an autonomous system in isolated locations.

Its major advantage lies in its ability to accept charging at very low temperatures, down to -20 °C, making it particularly appealing for cold environments, minimally heated technical rooms, secondary residences, chalets, or installations subject to harsh winters.

Thanks to its nominal energy of 5.12 kWh, it meets both the needs of daily domestic storage and serves as an energy buffer for a hybrid or off-grid installation. Its architecture also allows for expansion up to 32 units in parallel, to increase storage capacity according to the project's power requirements.

On the operational side, the battery includes a 4.3-inch screen and advanced communication functions in Bluetooth, Wi-Fi, RS485, CAN, and RS232, to facilitate monitoring of the charge state, access to parameters, and communication with compatible equipment.

Safety has also been designed for demanding residential use: intelligent BMS, 125 A circuit breaker, integrated precharge, protections against overcurrents, short circuits, overvoltages, and inrush currents, not to mention a reinforced metal casing for better mechanical resistance.
