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.

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.
