Solar Charge Controller


Solar Charge Controller

Simple charge controllers stop charging a battery when they exceed a set high voltage level, and re-enable charging when battery voltage drops back below that level.

Pulse width modulation (PWM) and maximum power point tracker (MPPT) technologies are more electronically sophisticated, adjusting charging rates depending on the battery’s level, to allow charging closer to its maximum capacity. It prevents overcharging and may protect against overvoltage, which can reduce battery performance or lifespan, and may pose a safety risk.

Charge controllers are often in conjunction with solar or wind power generators, for uses such as RV, boat, and off-the-grid home battery storage systems.

Eco-Sources provides mainstream PWM and MPPT charge controllers for your solar application needs.
