Chinese storage manufacturer Bslbatt has launched an off-grid battery for off-grid storage of photovoltaic power.

Dubbed the BSL Box, the new modular battery is described by the company as a low-voltage device with a storage capacity of 5.12 kWh that can be expanded to a capacity of up to 30.72 kWh through stacking.

The battery has internal connectors that eliminate the need for cable connections, and all external cables can be integrated into one connector, which the manufacturer says makes it easier to connect to the inverter.

The battery is said to offer stable operation for up to 6,000 charging cycles.

“The battery system has a service life of more than 10 years. In terms of compatibility, the BSL Box battery system can be used with well-known inverters such as Victron, Growatt, SMA, Studer, Fronius, Deye and Goodwe,” the company said in a statement. “Another feature is that the BSL box, when communicating with the inverter, enables the battery to be checked more precisely and battery data to be queried via the Internet.”

The company claims the battery can help offset peak usage. “Once installed, users can continuously monitor the consumption of solar panels and batteries through an application,” it also explained. “In short, thanks to the BSL Box, self-consumption can quickly be increased by 30%, thus saving energy costs.”
