Someone say recent PJ AMG models are junk , true. But he is still using three of those 2015 models (one 15kw and two 8kws). Will try to make them last as long as possible cause I know I can't replace them. I am using 2 PJ almost everyday and sometimes 24/7 . I change the rev 10.3 control board to the rev 11.1 and get the red light alarm . I run my PJ 15kw at less than 4 kw and no problem with the rev 11.1 control board . IT will not start my 4 ton heat pump . A trick is to run the heat pump for 2 minutes on grid and then connect to the 15kw PJ and run a 3/4 hp water pump for a minute turn and then switch on the 4 ton heat pump running both to start the heat pump and then shut off the water pump and the heat pump will keep running . I did that yesterday twice and it work with the rev 11.1 control board but I do not know why this work . Someone in this forum also connect a resistive load first and then start an inductive load like a refrigerator with the AMG PJ 8kw .

I need to be already running small loads on my inverter to make my "8000" AMG" start the refrigerator or a 1/2 hp motor.
Depends on your definition of "Junk".
While undoubtedly some of them work quite well, the lack of any confidence in what you'll actually end up getting is the problem. Every new inverter is an unknown quantity. How much power will it put out? How well will it handle inductive loads? Will it work at all?
It's not so much that the product is junk, it's that the QC reputation is junk.
the 30k powerjack turned out to be scams, but I did get the money back,,,I think I ended up paying credit card interest on the money even though all they sent was a piece of paper....still no more replies from powerjack-jack and that eBay scammer rayjunglepower...is no longer on eBay. just new scammer names at higher prices with the same ads....I rarely even look...but my powerjack inverters are all still running....I'd would say don't risk buying from them to anyone at this time....
I am glad that you got your money back and at this time I am not buying any PJ stuff . I have to see the youtube on the GS 12kw production model and the wires placement and crimp and how the primary choke fit in a tiny case .
All your inverters still running and the price you pay show PJ inverter are not junk and can run 24/7 .

My 15kw PJ was running a small 220vac load which is a 3/4 hp water pump in the swamp cooler for a minute and then start a 4 ton heat pump before disconnecting the water pump and continue to run the 4 ton heat pump I do not know why this work .
The PJ 8000 AMG seems to be $399 now, but still a bargain The comment from another post .
I recieve an email from Helen . She say she is still working for PJ in China in another department . She take care of the returns to Walnut not WALMART . I do not know if 399 dollars is a bargain . Only IF the inverter has a ASL5.0 transformer . She now also run the auction for PJ probably selling remanufactured inverter .

Besides the generally poor quality of literally anything powerjack is selling these days, the customer is faced with the problem that you just never know what you are going to get in any particular powerjack box. At least back in 2015 you could feel fairly confident that if you ordered a 15kw powerjack, you already knew what you would get. Then if you ordered another 15kw powerjack the next week, you could feel just as confident that you would receive another unit pretty much identical to the first one.
Today it is much different. No two shipments are the same, most don't actually or acurately reflect what was depicted in the ad, and none seem to be reliable at anywhere near their predecessors levels. The 15kw units I purchased in 2015 (I had three) would all do about 6kw reliably. Today's 15kw units are probably lucky to do 3kw reliably, and if you have to 'trick' them into starting motor loads, well, just no thanks. Time to move on to better things.

I do not run my 4 ton heat pump with the inverter . All the wires switching to use the heat pump is to see that it can be done . Too easy to backfeed the inverter and one mistake will blow up all the FETs . About 3kw at 110 degree F before the transformer overheat .
You can expect an ASL2 transformer and 2 capacitors on the main board.

Clark say I have a version 7 24v 8000w AS2 split phase that I've been very happy with. Bought it in January 2018.I live completely off grid. I had several off brand inverters before the power jack. This is the first one that actually worked. His 8000w AS2.0 transformer of 2018 is not the same as your new ASL2.0 AMG transformer .

You cannot even be sure of what label will be on a PJ product when you get it. I had ordered 3 identical UPower 3k units. Blew up the first one ( my fault ) so ordered the third to have two working ones. First two had the UPower labels and were shipped direct from China. Third one was shipped from here in the US and had a PJ label. Same UPower boxes and manuals. Same E-bay seller also.
