What's the Full Specification for sunpower solar panel?
Features High reliability with guaranteed -3% to +5% power output tolerance, ensuring return on investment High conversion efficiency based on leading innovative photovoltaic technologies Withstands high wind-pressure and snow load, and extreme temperature variations Attractive appearance Unique frame design, high mechanical strength, and easy Installation
Work: Under normal lighting conditions, put the unfolded solar panel toward the sun direction, then red and black alligator clips touch positive and negative ends of the battery respectively. If the “Charge” light red and the “Load1” light green , it shows that the system is charging the battery normally . At the meantime , it can load ( 12V light or other electric appliances ) connect to the L + and L- .
Protection Function: The solar controller have overcharge or undervoltage protection function for battery. When the charging voltage is higher than 14.4V , the controller will turn off charging automatically ; When the battery voltage is lower than the protection voltage 10.8V , the controller turn off output automatically to protect the battery from damage . At the meantime , the digital light flash and it can’t charge .
