Definitions

Battery Voltage (5100h)

  Battery system voltage for the application.

Battery Profile Parameters (5102h)

  Selects a battery discharge profile from  

the existing battery discharge profiles, including: 

 

0:  Flooded, Enersys E85 

 

1:  Flooded, Enersys E100 

 

2:  Flooded, Enersys E110

 

3:  Flooded, Enersys E125

 

4:  Flooded, Enersys E140

 

5:  Flooded, Enersys E155

 

6:  Flooded, Trojan T105

 

7:  Flooded, Trojan T890

 

256:  AGM, US Battery AGM-185

 

257:  AGM, Discovery EVGC8A-A

 

512:  Gel, MK Batteries M24

 

65534:  Custom parameters.

Battery ID (5103h)

  Battery can be assigned an identification number  

consisting of up 12 characters.

Depth of Discharge (DoD) (5105h)

  The DoD value scales the SoC displayed. 

Example 1: When DoD=80, the unit will report 0% SoC when 20% is left. 
Example 2: When DoD=100, the unit will report 0% SoC when 0% is left. 
The factory default is 80.

Charge Efficiency (5106h)

  The range for this parameter is 0 –100.  

A setting of 100 means 100% of the energy put in goes into charging,  
and none is wasted. 
Byte 5  Charge efficiency at higher charge rates; factory default=95. 
Byte 6  Charge efficiency at lower charge rates; factory default=100. 
High and low rates are determined by the Ampere-Hour Law.

Custom discharge parameters (5109h)

  If the battery discharge profile for the  

battery used in the application is not available, enter 65534 (Custom 
parameters) in 5102h and then create a custom discharge profile in 5109h.
