In darkness I disconnected the positive and negative wires coming from the Combiner box and to my surprise there was 26.6 volts at the wires. Obviously they are getting that voltage from the batteries (24v system).
Is that the way it's supposed to be?
Are the panels being backfed at night?
Thanks,
Peter
