The primary function is to regulate the voltage and current from a power source to a battery, preventing overcharging and optimizing battery life. It ensures safe and efficient charging by monitoring battery voltage and adjusting the charging process.
Typical input voltage ranges are 12–48 V DC for the battery bank voltage, and the maximum PV input voltage can be 100–150 V DC. These values are reference ranges; the actual model must be verified with the manufacturer.
It monitors battery voltage and reduces charging current as the battery approaches full charge. It switches to float mode, providing a small trickle charge to maintain full capacity without overcharging. Advanced controllers use PWM or MPPT algorithms for precise control.
Key parameters include input voltage range, maximum PV input voltage, rated charge current, conversion efficiency, standby power consumption, operating temperature range, and ingress protection rating. Always confirm these values for the specific model with the supplier.
