1. Increased MPPT charging current compared with regular controllers, the efficiency is more than 95 %
2. Battery support for Gel/lithium battery /AGM/fleece or acid/lead-acid, as well as LiFePO4 batteries .
3. Load output function with short circuit, overload portection function.
4. Bluetooth function, Phone APP display controller parameters( only MPPT5020-BT, MPPT5040-BT)
4. Automatic Charging: protections from overload, overheating, reverse battery and back discharge of the battery ( Avoid of insufficient solar power, such as at twilight, at night etc.).
5. Overcharge protection: Reduction of the charging current of the battery in case of excessive solar power and full battery. Immediate recharging in avoid of power consumption to ensure always the best possible charging state of the battery.
6. Connection for temperature sensor,Automatic adaptation of the charging voltage to the battery temperature. In case of low temperatures outside, full charging of the weaker battery is improved, and in case of summery temperatures unnecessary battery gassing will be avoided. This is highly recommended, if the battery is exposed to strong variations in temperature, such as in the motor compartment.
