Last solar panel added

Started last year with one panel, added a second one and this weeked #3 added. all panels are the same size, BougeRV 170w panels.

Decided to mount it sideways (vs lenghtwise in pic) as aluminum was pretty visible other way around.
sideways has more possible wind drag effect to added 2 more mounts to be sure it stays.

used 6 mounting brackets on front one, needed to fab a little block to make the side mounts work due to roof curve.

Also changed to a 40A MPPT renogy controller.
Sun still pretty low here up in SW Ontario but did see 320W (23A) coming into the 100ah lithium battery.

Nice job. So, 510W combiner on your roof, maxxed out? Mine's supposed to be 510W max input, but some have said it depends one which combiner you have, you may be able to add more. Can't recall the forum, but it came up in a solar/lithium thread. Might have been on here?
I'm running 300W flex panels up top (factory/dealer installed), and that's supporting 2 100Ah lithium Relion RB100-LT (low temp charging) models. If they go, I'll probably go to hard panels over top of what's up there already.
