Description

The 20A PWM Charge Controller 12v 24V Solar controller is also known as solar charge and discharge controller. It is used in solar power generation systems to regulate the charging of batteries from photovoltaic panels. And provide automatic control device for the voltage sensitive equipment load control voltage.

The 20A PWM Charge Controller 12v 24V regulates and controls the charging and discharging conditions of the battery. And it controls the power output of the solar cell module and the battery to the load according to the power demand of the load. It is the core control part of the whole photovoltaic power supply system
