[RE-wrenches] RETURN AMP SETTING

[Steve Higgins]

The only way for Outback gear to measure return amps is to incorporate
an FNDC in the installation.   

 

Otherwise then yes you are correct.

Steve,

 

Just to make sure I am not missing something, there is no way to
directly set Outback equipment for a particular return amp rate. Rather
one must observe the charge cycle and set the absorption timer
accordingly.

 

Do have that right?

 

Thanks,

Sorry all... I was out on a little three day vacation. 

 

I usually program return amps setting to usually 2-3% of the overall
battery bank capacity. 

 

Usually and depending on the battery type or manufacure when the current
passing from the charger to the battery drops to this Return amp setting
technically the batteries are charged.  

 

Because batteries are technically buckets of water with holes in them,
they will never stop pulling current, nor will they never be fully
charged.   What happens is they start to draw a minimum of charge
current from the charger.   This "Maintenance current" usually is
between 2,3,4,5 percent of the overall battery bank capasity. 

 

With the Return amps setting you can get the batteries close to that
charged setting.
