Solar regulator, SOL PWM 20A 2xUSB regulator is used to control the operation of autonomous photovoltaic systems. The device provides the correct characteristics of the charging current for the battery (s), additionally securing them against too deep discharge or overcharging. SOL PWM solar controllers can be used for installations with a solar battery and 12 or 24V batteries.
Automatic recognition of 12 / 24V input voltage
