Even in cloudy environments where the max power point of the solar panels will fluctuate all day. OUR DESIGN FOR YOU COPPER COILS True MPPT controller, The Three copper coils play a step-down roles to make your system work more stable. TRANSFORMER Three Electronic transformer, more safe MULTIPLE ELECTRONIC PROTECTIONS: Short-circutingReverse-currentOverchargingOverloadOver-dischargingReverse polarity protection FAN COOLING Good Heat dissipationIntelligence Fan-on temperature >45℃ and off Low voltage reconnect > Low voltage discharge.The solar controller will stop output when the battery under 10.7V. The LCD will be blank when the battery under 8V and it will re-output when the battery up to the 12.6V (adjustable).Install the Charger controller to the battery as close as possible. Tighten the wire, Carefully read battery manuals before operation.When controller makes buzzing sound because of It's working hard to dissipate heat for your controller. Rest your heart, it will be stop when temperature return to normal.Remove all the debris around the controller ( leaving a space of approx. 5.91in ).Make sure all connections going into and from the controller are tight. Do NOT let the positive (+) and negative (-) terminals of the battery touch each other.
