I should have mentioned I do have a combiner box with 3 15a curcuit breakers and 2 25a breakers. So I understand. However just didn’t know if it was “standard safety practice” to cover up panels when connecting if load is off. It certainly wouldn’t hurt and is easy enough to do.
However I am having another issue. I just connected my 2 24v lithium batteries in series to my Growatt 3000 LVM 48P. Please see attached pictures. After connecting using Anderson cables with 6awg, I turn on the batteries and they both read 25.3v and although I see no spark, nor thankfully do not feel any heat coming off the cables or connectors nor do I see any smoke, I am getting a distinct burning smell. Why I have no idea! I left the batteries on for about a minute and it didn’t seem to be getting any better, maybe even worse, so I turned them off thinking “this could get bad”. Any ideas? I don’t think I did anything wrong in the connections. Also the Growatt display did not turn on and I expected it to light up and recognize the batteries. Please advise and refer to pictures.
