solar charge regulator

Pulse width modulation (PWM) charging can double the life of a battery compared with On-Off charging, and typically sends 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.

• High quality marine grade pulse width modulation solar regulators for 12V systems with solar panels up to 150W. Made by Morningstar.
