Solar energy storage
14.336kWh Vertical Battery for Solar Energy Storage
The BSM48280W can be used as the battery component of a compatible residential solar-plus-storage system that uses a 51.2V low-voltage battery architecture.
Its 280Ah rating and 14.336kWh published usable capacity provide a larger amount of stored energy than the smaller wall-mounted models in the residential range.
The battery does not connect directly to solar panels. A compatible inverter and correctly designed electrical system manage charging, discharging and energy flow between the PV array, battery, household loads and grid.
Can the BSM48280W be used for home solar storage?
Yes. It can be integrated into a compatible 51.2V residential solar energy storage system after confirming inverter communication, voltage range, current limits and complete system design.
