Preface
Solar Charge Controller is battery charger that can charge batteries by the power from the solar panels. The charge controller is intelligent for charging batteries, using MCU and professional software to control the step of charging, can prolong the batteries’ life.
It has full self protection, protection of overload, short circuit, reverse connection, over charging and over discharging etc.
This model controller is 12V/24 Battery Auto-Sensing.
When the Battery is connected to the Charge controller, the controller will detect the voltage of the battery first, then it will decide how to charge the battery connected.
