Second, the solar..... minimal charge that would not keep up with minimal 12V usage on my second trip (3 days in the mountains). Checked the controller, 40VDC, checked the inputs on the roof, 40VDC, checked the individual panels, 20V/1A DC range. Got a couple new panels today, tested the old ones, 20V/0.3A range in cloudy snowy conditions, overlayed a set of the exact same new panels on the old ones, 20V/0.3A range, crap....
Moved the new panels to the back with full exposure and that doubled the current in each to 0.6A. So... Raspy was correct, the stock solar upgrade and maybe even the regular X22 solar system is bunk due to panel placement and shading of the AC housing, roof rack and plumbing vent. If anyone else perusing this forum has a functional "off grid max package" please inform, i do not see how this can be the case unless the sun is somehow seeing both panels completely. To compound the issue, they are connected in series which further derates what you can get out of them. The MPPT controller is great for the higher voltage series connection but the series connection needs full sun on both panels or overall current will take a hit as it will be constant through both and equate to the lower producing panel.
I will say at this time, the panels themselves arent the issue, its the installation. Moving the existing panels may kill them as they are screwed and adhered to the roof. Quite a bummer of an upgrade but i still stand by the components so far. Also I misread or misused a crappy current clamp (always blame the tools, haha) as i thought i was getting 9.0A range out of each panel but it was likely only 0.9A when i thought they were working great. Will post what i do to alleviate the solar issue and how it works out
