Item shipped quickly and securely. I hooked the 100 watt solar panel to the unit and it gave me a red light indicating that it was not sensing grid power (it is supposed to do this). I then plugged it in to an outlet and the red light turned off and the 3 green lights started flashing indicating everything was working and it was producing power. Can't be much easier than that!

I bought 2 of these to experiment and have been running them with two identical 36cell 100W panels for about 4 months now. They work!Some observations:- The best efficiency I've measured is about 80-85%, not the 90%+ listed in the spec- Running 2 100W panels in parallel nets me about 125~130W output- Running 1 100W panel by itself on each GTI nets me about 70W each or total of 135~140W combined- Repeated measurements over varying sunlight conditions show me these units run most efficiently when they only have a single panel attached to them.Just a heads up to avoid disappointment! My panels are spec'd at 100W each in 25C ambient lab conditions; in reality it's less due to temperature derating. At midday in June, I was measuring the backside of my panels to run about 55C. With a 0.5%/C derating above 25C ambient, the panels can theoretically put out only 85W. Considering the GTI efficiency to be about 80-85%, max power from my panels is only about 70% of the panel rating, best case. In my 200W panel setup, I can only expect to get at best about 140W, tops in the middle of the summer. Most of the time, I see 130-135W more than I see 140WI opened my SUN300G and compared its innards to pictures of the SUN250G. Both look identical and I'm not sure what the difference really is. There is a single 35V, 4700uF aluminum electrolytic capacitor for filtering on the front; it seems to be a bit undersized and underrated. I see over 2-3VRMS of 120Hz AC ripple on the input when I'm running both 100W panels in parallel, and it probably explains why the cap runs warm (not good for longevity) I attached a single 1000uF cap on the terminal lugs and it brings the ripple down a bit while squeezing about an extra couple watts out of it. Ironically, a 10000uF cap cleaned up the input ripple quite a bit more, but it yielded about 4-5W less output. I surmise the MPPT is measuring peak input voltage rather than an average DC input.If I was to do it again (I probably will), I'd probably buy the SUN250G and attach a single panel to each since the biggest 12V panels don't come in anything much beyond 150W.

Uses almost half of my panel output just to convert over to A/C. Good unit but not very impressed with the output. Fan kicks on often if you put more than 100 watts through it.
