Advantages
SunGuard’s PWM charging compared to On-Off solar regulators:
- Typically 30% more solar energy into the battery per day.
- Average battery State-of-Charge is 90 - 95% compared to 55 - 60% for On-Off regulators.
What is PWM ?
Pulse Width Modulation "PWM" is the most effective means to achieveconstant voltage battery charging by switching the solar systemcontroller’s power devices. When in PWM regulation, the currentfrom the solar array tapers according to the battery’s conditionand recharging needs.
