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:

Mgmt Mode
(Management
mode)
Auto, Manual Auto
In normal situation, it should be in the “Auto” mode, which enables
the monitoring module manage the whole power system
automatically, including: Automatic FC/BC switchover, LLVD and
BLVC. In the manual mode, you can do operations like BC, FC,
test and battery on/off, as well as enabling automatic battery BC
time protection and capacity calculation. Upon the system DC
under-voltage alarm, system can automatically switch to the “Auto”
mode, lest wrong manual operation should damage the system
Batt String
(number of
battery strings)
0 ~ 4 4
You should set this parameter according to the actual battery
configuration. If “Batt Shunt” is set as “Y”, there should be batteries
actually configured
Rated AH (rated
capacity)
50 ~ 5000Ah 300Ah
The capacity of a single battery string. You should set this
parameter according to the actual battery configuration.
BTT Name 1# ~ 11# 1#
Battery Name 10 characters Name different battery types to identify them
Batt Shunt1 Yes
Batt Shunt2
Yes, No
No
Select “Y” when a corresponding shunt is configured, otherwise,
select “N”. Battery management aims at only the batteries
connected to the shunt
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.
5.7.3 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.
