The weight of MT6020PRO is very heavy, 5kg, this proves we use one big heat sinking board, so the heat dispatch is good. It will work well in high altitude area, can work stable, work long time.
MT6020-Pro can charge 12V battery, 24V and 48V battery. There is one data logger inside, with 5 years memory.
And there are two relays to control like Diesel generator, and other devices like inverters or loads. And one AUX port for other signal application. One RS485 port for communication. Also can add Bluetooth function. And you can program the charging voltage as you like, the boost / equalization/ float charging voltage, also LVD and LVR.
