The M215C charge controller is an MPPT type controller that can work with 12V and 24V batteries with maximum charging currents of 15A.

The regulator is equipped with an RS485 serial port with ERABUS protocol. The serial port allows you to set the regulator's charging parameters based on the system's battery, create master-slave systems between regulators connected in parallel, and communicate with the BM39, BM40, and BM40W series displays.
