Automatic Recognition SD 24V 20A PWM Charge Controller
It uses digital output of microprocessor to control analog circuit. Constant current, constant voltage and floating charging are adopted. The PWM solar controller solves the problem that the battery is not fully charged and the life of the battery is short.
It can be used in small-user solar power system for home, street light, water pump, solar water heater, etc, which controls the charging of solar panels by batteries and the batteries supply power to inverters and loads.
