It's not uncommon to see voltage on panels at night, but usually, there shouldn't be significant current. if you've isolated your string and short-circuit the panels for a second or two the voltage and current should go to zero as their capacitance fades.

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? Voltage.
Pick a combiner box that fits your system’s voltage and current. This helps keep your system safe and working well. Always connect solar panels with the same voltage. This stops power loss and keeps your inverter safe from harm. Check and take care of your combiner box often. This helps your solar.
