1. The solar controller is only available for lead-acid batteries. Open type, AGM, gel type. It is also suitable for Ni-MH, Li-ion or other batteries 2. There are many types of MPPT technology, our solar controller Mppt technology detects the maximum charging current instead of the boost type or automatic charging of the solar panel voltage. This MPPT controller can increase efficiency by 10-30% compared to a normal solar charge controller. 3. If the battery voltage is too low, the control unit automatically switches off the load on the system. When the battery voltage is back to normal, the load will be put back into operation. 4. This MPPT controller has a perfect SOC function to control the charging current and power the load. Prevents battery overcharging, over-discharge and reverse charging of the solar panel at night. 5.
