Mr Wiz, I am baffled by the amps always falling while SOC rises idea, when amps are constant during the Bulk stage. Charging amps do fall at the beginning of the Absorption stage and continue to taper.
(Ignoring that little funny part just at the transition between Bulk and Absorption where definitons get muddled)
Battery acceptance in amps goes down as SOC rises, but the current limited charger comes in at below the acceptance rate and holds steady until charger amps = acceptance rate (at that voltage and SOC) when amps then taper.
The gen supplies the VA for the charger doing 75 amps at 50% SOC until say 73% SOC. Battery "resistance" keeps rising that whole time.
I have only spot checks to see what VA is over that Bulk stage and not enough to see if VA goes up with SOC.
I was surprised to be told in this thread by one and all that it does. I can see that output watts goes up with rising battery voltage. That would make peak input watts be just at the end of the Bulk Stage. If PF is changing during the Bulk stage too, then I don't know what happens with VA.
EDIT- input watts might not peak there if efficiency is changing too. Gottaluvit.
Yes I am confused. (My usual state :) )
