While most Solar Charge controllers are of the buck type (Solar panel voltage must be higher than battery voltage) this controller is a boost. So the panel voltage needs to be lower. Applications for this are endless, such as charging a golf cart 36 or 48v battery with a single solar panel. Or charging an ebike or scooter battery!
Voltage Input (VOC): 18-55V
Voltage Output: 24-85V adjustable
Current Output Max: 15A
