This MPPT step-down real-time tracking solar battery recharging controller with the LED display, and the output voltage can be adjusted, and suitable for le-ad-acid, lithium-ion and other batteries in line with 10~30V recharging voltage. Come on and try it, it will not let you down.

Features:

With the LED display to show the input and output current and voltage, you can see the data more clearly.

The output voltage can be adjust between 10~30V, you can choose the suitable for your needs.

Suitabe for the le-ad-acid, lithium-ion and other batteries in line with 10~30V recharging voltage.

Efficient MPPT real-time tracking function, give you a better using experience.

Overheat protecting function: When the internal ambient temperature of the MPPT controller exceeds 100 Degrees Celsius, the output power of the MPPT controller will be reduced. If the internal ambient temperature continues to rise to 110 Degrees Celsius, the output of the MPPT controller will be automatically turned off. When the internal ambient temperature of the MPPT controller falls below 85 Degrees Celsius, the MPPT controller will automatically resume operation.

Short circuit protecting function: when the MPPT controller output comes unexpected short circuit, MPPT controller will automatically close the output, the short circuit will automatically return to normal after elimination.

Input under-voltage protecting: when the MPPT controller input direct current voltage is lower than 15V, MPPT will protective shutdown, the input voltage is normal automatically resume work.
