It is easy to do a dock
test as I did with my 50A & 70A chargers (@24v)
I let the bank draw down 65% and shut off all DC consumers.
Also all AC consumers so I could measure the efficiency of the different chargers combined and individually.
By measuring charge rates thru the Bulk range and into Absorbtion while logging the difference combined and individually I was then able to identify when to turn the 2nd charger off.
Repeated test 3 times to confirm results and made a nice spreadsheet for future checks of house bank condition.
