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 Higgins. Sr Application Engineering Mgr Sub-Saharan Africa Business Dev Mgr.

Rather one must observe the charge cycle and set the absorption timer accordingly. Do have that right?

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. Steve Higgins. Sr Application Engineering Mgr Sub-Saharan Africa Business Dev Mgr.
