If the diverter parameter is set to ‘set’ in the system type setting, the diverter
coefficient setting field will display, or the diverter coefficient is default. Two
packs of batteries have same diverter coefficient
LVD setting
Function description
LVD1: LLVD, which 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.
LVD2: BLVD, which means the monitoring module opens the BLVD contactor. In this way, the battery will stop
powering the load, preventing over-discharge.
The setting interface is divided into three screens, as shown in the following:
LLVD ENABLED

Mode: Voltage
LVD VOLTAGE
LVD1: 44.0V
LVD2: 43.2 V
LVD TIME

If selecting the ‘According to voltage’, when the monitoring module detects that
the battery voltage is lower than the setting value of ‘Load LVD voltage’, the
monitoring module disconnects the load LVD contactor. When the monitoring
module detects that the battery voltage is lower than the setting value of ‘Battery
protection voltage’, the monitoring module disconnects the battery protection
contactor.
If selecting the ‘According to time’, when the battery discharging time reaches
the setting value of ‘Load LVD time’, the monitoring module disconnects the
power-off contactor. When the battery discharging time reaches the setting
value of ‘Battery protection time’, the monitoring module disconnects the battery
protection contactor
