That would be a good place to start for sure.
Also check if the other panels are a match with each other, We might get you to a good 510 W system yet
This will help with not taking the battery's as deep a discharge & make them last longer.
Again, thank you for your patience!
Just checked the voltages (but they mislead me before! - I will explain)
Roof panels, 20.8, 21.8, 21.1.
Vertical panel 20.4
However, the roof panel at 20.8 is putting in no amps!
The other 2 roof panels are putting in 4..0, and 4.5.
The vertical panel 1.6. at the time of recording.
So one roof panel has failed.
i checked the voltages before we left and thought it was ok as it read 20.8.
however its mate died 2 years ago, and I have be suspicious, but we will no go there.
I did a big post about it when it failed, and go one post deleted because of it!
So given that the sun is not right up there yet, I expect the remaining roof panels to do the job for us this trip.
Then I will get another panel, and attempt to repair the failed one.
Water will have got inside it and corroded some connections inside, it might be a throwaway item.
And I will get another controller, I only intend, long term to have about 120-240 watts vertical so all will be well.
And I will have 360-480 on the roof. But the problem with me has been adding like topsy, as I could afford to, rather than 1 big jump!
