I have two 24 volt battery
banks, one starter and one house, both (2) 12V in series.
My recently installed Xantrex 3024 inverter/charger seems to be not functioning correctly.
The Xantrex unit charges my house bank and an Echo-Charge unit level charges the starter bank.
Until I can deal with the Xantrex unit I am using my manual 12v charger
to charge both banks. I was disconnecting the cable between the two batteries
to make them stand alone 12v to charge. Today when I was checking the 24v battery
voltage with my DVM to compare to the digital readout on the DC panel I noticed that by checking the pos and neg on each battery even thought they are still tied to together to make 24v I get the 12v readout.
I hooked up my 12v charger
to the pos and neg on one battery and the panel voltage went up from 23.3 volts to 24.7. The battery is pulling 14 amps from the 12v charger.
Is this ok to do? It would save me from taking the cable between batteries
off to charge, but I don't want to damage my $2000 battery investment.
