The Sunforce 8.5 Amp Pro Series Charge Controller is ideal for protection of your solar panels and batteries. Built with reverse polarity protection, this product is designed for use in small solar systems where a load disconnect is not required, such as yachts and RVs. Small and compact, this controller is equipped with an integrated temperature compensation function that enables use at a broad range of operating temperatures. Pulse width modulation and boost charging allow for more efficient solar power systems. This product handles up to 127.5 watts of solar power.

Key Component of a Solar System Over 15 Watts

A charge controller is a very important feature of a solar system and must be used on all systems over 15 Watts. A charge controller protects your batteries from overcharge and discharge. Charge controllers are the maintenance free protection of your solar panel and batteries.

A charge controller monitors the battery’s state-of-charge to insure that when the battery needs change-current, it gets it, and also insures the battery isn’t overcharged. Connecting a solar panel to a battery without a regulator seriously risks damaging the battery and potentially causing a safety concern.

Charge controllers are rated based on the amount of amperage they can process from a solar array.
