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.
