SUN-600G 600W Watt MPPT Micro Grid Tie Solar Power Inverter Solar Panel 120V AC NEW US Seller

I have two different SUN GTI inverters, a 500Watt one and this 600 watt SUN-600G. Both are driven by 3 170 Watt BP solar panels for a total of 510 watts each. The 500 watt inverter was purchased first and I never got more than 400 watts out of the inverter. Then I reviewed the specifications and saw the max output rating is 450 watts not the 500 watts I expected. I looked at this inverter and saw that the rating is 540 watts for the 600 watt inverter. Both inverter are now running and the output is the same on both inverters, neither one outputs more than 400 watts into my home grid. A big concern on this 600 watt model is that the fan NEVER comes on. On the 500 watt unit the fan cycles all the time to keep the unit cool. The 500 watt unit has a red fault led and 3 green leds to indicate it's status and operation. The 600 watt model has one single LED and the booklet/manual does not address anything about this model. I most likely will remove the 600 watt unit until I figure out how to make the fan/cooling system function.I mounted both devices two ways. At first they were mounted in the garage and fed with heavy copper wire. Then I mounted them at the solar panels and ran the AC power into the garage. Except that it is cheaper to run the AC wire than expensive heavy wire for DC, I get the same output from the GTI devices.So the things work, they just don't work at the rated wattage.

The media could not be loaded. Solar Panels not included!Saw this 600W inverter on Amazon and thought I would give it a try and see if I could reduce my electric KWH. Hooked the inverter to a couple of home made PV panels (~240W). I have the panels wired to a cheap charge controller which then charge a couple of truck batteries. PV panels are on porch as this is a test set up I've been working on since last winter. Panels are not getting direct sun light now that it is Summer. Very easy to hook up. Initially inverter put out about 180 Watts per my Kill-A-Watt meter. Output dropped to around 25 Watts and charge controller started to show low battery voltage. Also, noticed the green LEDs were now only flashing (1-3-1-3-1-3) , instead of the initial 1-2-3-1-2-3-1-2-3.Picked up four Evergreen 210 Watt panels and mounted two of them where they would receive full sun. Hooked the two Evergreen panels to the inverter in parallel ( 12V+ @ about 22A ). Inverter put out about 260 - 290 Watts. Still only 2 LEDs flashing (1-3-1-3-1-3-1). Thinking the inverter could be defective, I ordered two of the 250 Watt inverters. When the two 250 Watt inverters arrived I hooked them up one each to a single panel and piggy-backed into the Kill-A-Watt meter. Output was about 250 - 260 Watts. Hooked the 600W inverter back up, but today is overcast and output is ~30W.Bottom line is that the inverter does work (even if only 2 LEDs are flashing) and under light household load the electric meter runs backward. Saved about 8 KWH this week per the Kill-A-Watt meter. (5 sunny days @ 45 degrees North)(Note: As this is a Grid Tie Inverter it must detect 120VAC when it is plugged into the wall outlet. If your power company's power goes out the inverter stops working. This is a safety design function to protect electric company linemen.)(Note: Unlike the old analog electric meters the new digital Smart electric meters will not decrement the KWH number even if the meter shows it is running backwards.)Reasonable price. Shipped quickly and received within several days. Packaging OK, some minor over pack box damage, but product box OK.

Advertised to 60 volt input it did not accept 2 12 volt panels in series. Customer support was worthless. It accepts 12 volt panels but will not exceed 130 watt output. Stuck with a lemon.

Easy to wire but came broke the light just blinks saying I'm not putting in any power but I have power showing at the wire connection im vary disappointed

This power inverter works very well.Give me a good power.Help me to reduce energy cost.Actually this is the inverter number 4,I installed in different houses of my family.

I bought 5 of these to pair them with my 10 230-watt panels, one for two panels.They do work but when I went to get things permitted and approved with my electricity provider, I found out there is no certification for them.Yes, the description says they do anti-islanding which is all great but without the certification to back it up, nobody will allow you to tie these to the grid.And if you think you're tying these to the grid without your provider knowing, well, if you have a smart meter (not the mechanical kind) then you will actually be paying for the electricity you push out as well in some scenarios. For these things you just have to follow the rules.Long story short, i'm getting rid of mine as this seller wants a 20% restocking fee to take them back.

has been working good for several months now, but using at only half capacity, to extend the life. these are a little better than some cheaper models, if used properly, could last a long time, sometimes it's a little slow to start up, probably trying to find mppt, then works good

I am not sure that I understand Edward's review at the top. I would *not* attempt to pair two or three solar panels in the 200-250-280 watt range with this 600 Watt inverter. I have two 280 panels whose specs should have fallen within the tolerances of this unit. I connected the panels in parallel and the inverter fried within the first day. Not only did the 30 amp auto fuse melt into a black blob, but one of the capacitors literally exploded strewing really nasty smelling black stuff all over the inside of the case. I would pair this 600 Watt inverter with a single 280-300 watt panel. Otherwise, you are taking your chances. I do not believe that these units operate anywhere close to specs. I am waiting for a 1000 watt unit to arrive and will try that. From what I can see on YouTube, this isn't the worst of all available solar grid tie inverters. It does seem a bit more solidly built than the units that self-disintegrated and made it onto the YouTube hall of Solar Shame. But don't push it close to its advertised limits. You will end up with a stinky smelling metal box.
