★ When an LFP or LNCM battery is used, the system voltage can't be identified automatically. Please
confirm the system voltage before operating.
◆ When an LFP or LNCM battery is used, the temperature compensation coefficient will be 0, and can't
be changed.
Environmental Parameters
Working
temperature
-30℃～+65℃ (when the working temperature reaches 50℃, the
charging power and load power will be reduced appropriately; working
of full load is not supported.)
Storage temperature
-20 ℃～ +70 ℃
Relative humidity
< 95% (N.C.)
Enclosure
IP30
 During -30℃～+50℃, the controller can full load work. When the internal temperature of the
controller exceeds 81℃, the charging power automatic reduction function will be enabled. Details
refer to 4.1 protections. When the working environment temperature exceeds 50°C, the actual load
power needs to be derated. Every increasing 1°C in temperature, the actual load power needs to be
reduced by 2.57% of the rated load power. For example, when the working temperature reaches
60℃, the actual rated power for load 1 will be 100W-0.0257*（60-50）*100=74.3W. The load power
variation curve with temperature is shown in the figure below:
