Hello, I recently received my AC200MAX and everything seemed fine until I tested solar. I put three 100W 12v panels in series and hooked it up and it started charging. It’s a little hazy today so I didn’t expect anything near 300w, but was suprised when it was only about 80w. I did a bit of testing, but I’ll skip to the end of my testing. I have two 100w panels in series on a slighty hazy day with a inline meter. When I hook this up to my AC180, I get between 130-135 watts both shown on the AC180 and the inline meter. When I switch the panels over to the AC200MAX, both the display and the inline meter show between 62-72w. I’ve gone back and forth between the AC180 and AC200MAX, and no matter the lighting, the AC180 always seems to show nearly twice the watts as the AC200MAX.
The AC200Max doesn’t show it needs any firmware upgrades. Current versions are:
Any suggestions on what’s going on?
Should I go ahead and contact support? I really hope I don’t have to ship it back
Thanks for any help,
