Protection
Parameters		Min.	Typ.	Max.	Unit	Remark
Power Module	Over temperature  protection	The power supply module has the function of over temperature protection. When the main radiator temperature too high and up to over temperature protection set point, turn off the output, temperature hysteresis is about 10ºC
	Output over current protection	Each module of the power supply has the function of over power protection and short circuit protection.

Battery management function
Battery management	DC charging	With MPPT, use the maximum power to charge
	AC charging	AC constant current charging firstly, then constant voltage charging.
	Over/under voltage protection	Battery comes with BMS management.
