what is solar charge controller

Solar charge controller is to protect the battery, to prevent over-charging of an electronic component in most solar power systems are included in the charge controller, its most basic function is to cut off the charging current when the battery is full, due to various batteries Charging characteristics of different, so should be selected according to the type of battery charge controller.

1. buy solar controller must know the solar panel power and load power to be used to determine the controller's charge current and discharge current.

General solar controller is 12v / 24v automatically identified. Discharge current = load power / 12v, charge current = panel power / panel voltage. Panel voltage can be measured with a multimeter DC file. Short-circuit current in the battery board clamp meter to test the current. This battery power = voltage * current, the basic knowledge of the solar panel power. Battery charging current will know.

The controller current range is greater than the solar panel charging current and load discharge current.

2. the controller must have battery over-voltage protection, battery under-voltage protection, load short-circuit protection, temperature compensation and other functions, choose the controller selected quality assurance.
