Product Description:

1. Increase the charging current, compared to the traditional PWM controller, MPPT charging efficiency can be increased by 10-30%. (Controller conversion efficiency> 95%)

2 can be selected by DIP switch 4 batteries. GEL battery, lead-acid (liquid) battery, AGM2 battery, LiFePO4 lithium iron phosphate battery

3. With load output, with over discharge, overload, short circuit protection.

4. With Bluetooth function, you can view the controller parameters through the phone APP display (MPPT5020-BT models only)

5. Automatic unattended charging. With overload, overheating, reverse current protection (cloudy or no sunlight at night, to prevent the battery back to the solar panel)

6. Overcharge protection. When the battery is full, the charging current will be reduced, when the battery is dead, it will immediately charge the battery

7. Automatic temperature compensation. Ensure the battery in the low temperature or high temperature environment, the use of charging parameters to extend battery life
