CACAGOO 200W/300W/400W (Optional) MPPT Step-down Real-time Tracking Solar Battery Recharging Controller LED Display 10~30V Output Voltage Adjustable Dustproof Fluid

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.
