I have no useful info to add but posting to follow since I’ve got one of their 220s that’s kind of flaky and have been debating poking around inside.

Full sun in the fall and it was waffling between 0w and ~18w while feeding an AC200P. But the next day with almost exact conditions and location it was getting around 180w for awhile at least.

Then life got busy and 9 months later I haven’t retested. It was “free” with a promotion though.
