Charge and discharge characteristics:

Battery communication and management

The 12 V battery has a simple BMS and balancer built in. The BMS monitors and controls the individual battery cells and protects them from damage such as overload and overvoltage. It consists of finely balanced cells with identical performance. The battery must be managed and operated as a single monolithic 12 V block.

For communication with inverters, the battery uses 2 interfaces, RS485 and CAN. Both interfaces are integrated into a single connector located on the top of the battery.

To communicate with the battery, download the "SMART BMS" app to your smartphone on
