This solar battery charge controller is a smart tracking algorithm using MPPT charging technology and has less power loss performing at 97.5-99% efficiency, maximizing energy harvest. The tracking algorithm is automatic and varies with weather conditions. This charge controller also has temperature compensation protection using the included battery temperature sensor. Charges 12, 24, 36 and 48 volt solar systems with multistage charging technology and adjusts according to battery type.
The MPPT charger controller includes LCD display to show charging status and faults. An LCD displays key information such as battery voltage, solar panel voltage, solar panel charging current and charge mode. Users are able to revise and set the default parameters according to system design.
