5.7.6 Temperature Compensation Coefficient Parameters
1. The first page of the setting interface is shown below:
Temp 1:
Ambient
Temp 2:
Battery
2. If the “Temperature1” or “Temperature2” is set to “Battery Temp”, you need to set
the following parameters:
Center Temp:
25°C
Temp. Comp:
70mV / °C /Str
Batt Temp Alarm
Over: 70°C
High: 50°C
Low: 0°C
Use “” or “” to select one page or one of the parameters, and “” or “” to
select the parameter value. Press “ENT” to confirm and save.
3. The value description of the parameters is listed below:
Table 5-14 Value description of temperature compensation coefficient
Parameter Range Default Value description
Temp 1
Temp 2
Ambient Temp,
None, Battery Temp None
The “Ambient Temp” and “Battery Temp” refer to the
measurement of the ambient or battery temperature
sensor at the local power system. “None” means there is
no measurement input. You should set the parameter
according to the actual situation. The temperature
measurement data will be displayed in the system
operation information screen.

The default is
72mV/°C for
48V system
and 36mV/°C
for 24V
system.
Batteries are sensitive to temperature. To ensure
battery’s capacity and life, its FC voltage should change
together with the temperature: lower FC voltage for higher
temperature, and vice versa.
<FC = BattTemp – Center Temp % Temp Comp
Upon alarms such as “Rect Com Failure”, “DC Under-volt”
and “DC Voltage High”, the monitoring module will not do
temperature compensation to the battery FC voltage.
Set this parameter according to the actual battery
technical parameters
