I have the AC300 system with 3 sets of 350 solar panels. I tried to chain them together and get 0 charge. When I hook 2 up to the pigtails I get the 068 Parallel error. What can I do to get my panels charging my batteries?
Did you connect them in series?
Perhaps if you provided some additional detail on how you are connecting your panel cables it may be of assistance with resolving your question.
I believe I connected them in series. panel 1 red (male) to the AC300 pig tail 1 black. panel 1 black (female) to the panel 2 red. panel 2 black to AC300 pig tail 1 red…
Then I tried panel 1 red (male) to the AC300 pig tail 1 black. black (female) to the panel 2 red. panel 2 black to panel 3 red, and panel 3 black to AC300 pig tail 1 red.
Both caused 0 charging.
When I plug panel 1 into pig tail 1, and panel 2 into pig tail 2. (blak/red)… I get charge from both. But then panel 3 is no good, not connected to anything.
Hi @dlfuller , sorry for inconvenience.
I’m very sorry that based on your description we can’t know very well how you connected the solar panel. Can you take a video to show us? That would be a little more visual. Thank you very much for your cooperation
