Solar Charge Controller

pulsewidth Modulation (PWM) charging is the most effective means to achieveconstant voltage battery charging by switching the solar systemcontrollers power devices. When in PWM regulation, the current from thesolar array tapers as recharging needs. Charging a battery with a solarsystem is a unique and difficult challenge. In the old days,simpleon-off regulators were used to limit battery out gassing when a solarpanel produced excess energy. However, as solar systems matured itbecame clear how much these simple devices interfered with the chargingprocess.

What is PWM charging?

Instantaneous overload when load current is greater than programmed value.

Overload at 2 sec when load is greater than programmed value.

Overload at 4 sec when load is greater than programmed value.

Overload at 20 sec when load current is greater programmed value.
