Swiping your meters , not cool Bad China.

I tried to order some of those 60w panels last year. But, their shipping info
was bogus. The shipping costs more than the panels..

The Power Jack model I wanted didn't have an LCD watts-volts display, and I told them.
So, they build the same unit again, and didn't install the LCD board!

I'm almost ready to try again.. That big one will have room inside (I hope)
to install RFI-EMI filters, an SSR & etc.. I'm thinking of buying one!!
But, I would get the high voltage model (50-100vdc), so I won't have to
reconfigure my panels. It would be plug-n-play, since they run about 68vdc.

(I would sell the one I have now on-line. It's a 28-52vdc 120ac).

My idea was to get a cheap GTI setup to use to supply some extra kick
to my back-up 5kw gas back-up generator.
If I could get about 400w of PV backing the gas gen, it would use less gas
and I could get a longer run time.

It's likely we will never have another long black-out, so this stuff will most likely never be used..
And, I guess that's a good thing..
