Startup of the Controller: Efficient and User-Friendly Operation

The controller features an automatic self-test function that initiates immediately upon connection to the battery, ensuring the MPPT Solar Charge Controller is ready for normal operation. It can accurately identify a 12V system voltage, with the ability to recognize battery voltages between 10V and 15V during startup. If the voltage is outside this range, the controller will display an error state, guiding users to troubleshoot based on the fault description. Additionally, this series of controllers supports both liquid and gel batteries, with a factory default setting optimized for liquid batteries.

Key Advantages:

Automatic Self-Test: Ensures the controller is ready for operation upon startup.
Accurate Voltage Detection: Identifies 12V system voltage within a safe range.
Versatile Battery Compatibility: Suitable for both liquid and gel batteries.
User-Friendly Error Display: Guides troubleshooting with clear fault descriptions
