Hi
I have connected my Victron 100/50 smart charger to a single 180W 36V 5A using 6mm2 cables. The voltage when I switch it on fluctuates from 38v to 14v every 30secs. It’s a sunny day.
When I disconnect the charger and meter the panel it reads 38V. I’ve by pass the 32A Isolation switch and run straight to the charger as someone else on here had the same issue and said it was the CB they were using that was causing the problem.
