3.If setting parameter “System Type” requires setting the battery shunt coefficient, the second page of the basic battery settings is as follows:

Batt Shunt1: Yes

Batt Shunt2: No Shunt Coeff: 300A / 75mV

4.The value description of the basic battery parameters is listed below: Table 5-10 Value description of the basic battery parameters

Parameter		Range		Defaults		Value description
						In normal situation, it should be in the “Auto” mode, which enables

5.7.3LVD Parameter Description

1. Function description

LLVD means the monitoring module opens the LLVD contactor, so that the non-priority load will be powered off. In this way, the battery remaining capacity can sustain the priority load longer.

BLVD means the monitoring module opens the BLVD contactor. In this way, the battery will stop powering the load, preventing over-discharge.
