Solar Charge Controllers

Solar PV Charge Controllers are a integral part of any solar system to prolong the life of batteries. They take the uncertain voltage from a solar panel and condition it to safely charge lead acid batteries. These solar PV charge controllers use pulse width modulation (PWM) or Maximum Point Power Tracking (MPPT) , and a 3 or 4 stage charging method, bulk, absorption, and float (maintenance) charge. They also protect the panels from energy backflow from the solar batteries after the sun goes down. Solar charge controllers are necessary to protect your PV investment. We carry Phocos and Morningstar charge controllers.
