Battery Max Recharge 
{Status Only} 
[System/DC Parameters] 

This is just a convenient place to view 
the Battery Max Recharge Current 
parameter.  Go to Batteries/Parameters 
to change setting. 

Status Only 

Battery Maximum Recharge 
Current 
[Batteries/Parameters] 

One of three parameters that control the 
dc output voltage.  If Battery Current 
surpasses the Maximum Battery 
Recharge Current, the dc output voltage 
will be reduced (the system limits the 
charging current to this programmable 
value). 

0 – 10,000 A, 10 A 

Battery Temperature 
[System/DC Parameters] 

Battery temperature measured by the 
system controller at the optional battery 
temperature sensor probe. 

Status Only 

Battery Temperature 
Compensation High Knee  
[Batteries/Parameters] 

The temperature compensation high 
knee is the point where there is no 
additional battery voltage compensation 
for further increases in temperature. 

0 °C – 100 °C, 40.0 °C 

Battery Temperature 
Compensation Low Knee  
[Batteries/Parameters] 

The temperature compensation low knee 
is the point where there is no additional 
battery voltage compensation for further 
decreases in temperature. 

-100 °C – 100 °C, 0.0 °C 

Battery Temperature 
Compensation Method  
[Batteries/Parameters] 

One of three parameters that control the 
dc output voltage.  Activate “ON” or de-
activate “OFF” battery temperature 
compensation.  

ON, OFF 

Battery Temperature 
Compensation Temperature 
Coefficient 
[Batteries/Parameters] 

Temperature compensation coefficient 
between low knee and high knee in 
mV/cell/°C.  (Compensation equals zero 
at 25°C.) 

-4.99 mV – 0 mV,  
-3.00mV
