Yes, No
Yes
Select “Y” when a corresponding shunt is configured, otherwise, select
“N”. Battery management aims at only the batteries connected to the
shunt
Batt Shunt2
Yes
Shunt Coeff (shunt
coefficient)
Dependent on system type
In the system type setting, if the parameter “Shunt” is set to “Y”, this
parameter will be displayed. Otherwise this parameter will take the default
value, and is the same for both battery strings
4.7.3 LVD 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.

Voltage
Select “Voltage”, when the monitoring module detects that the battery
voltage is lower than the prestet “LLVD Volt”, the load will be disconnected,
and so is the battery when the battery voltage is lower than the preset ‘BLVD
Volt”.
Select “Time”, when the discharge time reaches the preset “LLVD Time”, the
monitoring module will disconnect the load; when the discharge time
reaches the preset “BLVD Time”, it will disconnect the battery
