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 pro-tection function: When the internal ambient temperature of the MPPT controller exceeds 100℃, the output power of the MPPT controller will be reduced. If the internal ambient temperature continues to rise to 110℃, the output of the MPPT controller will be automatically turned off. When the internal ambient temperature of the MPPT controller falls below 85℃, the MPPT controller will automatically resume operation.
Short circuit pro-tection 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 pro-tection: when the MPPT controller input direct current voltage is lower than 15V, MPPT will protective shutdown, the input voltage is normal automatically resume work.
