Integrated Power Systems > Charge Controllers

Charge controllers or charge regulators are basically voltage and/or current regulators to keep batteries from being overcharged. It regulates the voltage and current coming from the solar panels going to the battery. Most “12 volt” panels put out about 16 to 18 volts, so if there is no regulation the batteries will be damaged from overcharging. 

Charge controllers come in all shapes, sizes, features, and price ranges. They range from small 4.5 amp controllers, up to 60 and 100 amp MPPT (Maximum Power Point Tracking) programmable controllers with computer interface. mppt IV graph

All our systems use MPPT charge controllers.    

Innovative MPPT technology ensures that your solar array is operating at its peak power regardless of age, shading or environmental conditions – increasing the performance by up to 30%.
