Constant Voltage 24V 25mm Wire 20AMP Solar Regulator
Model: SD-20A
Max charging current: 20A
System voltage: 12/24V(auto recordnized)
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.
Application Area:
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.
