the only two bad reviews i seen was the incredibly long shipping time and the inverter being noisy,,, one was a you tube review and one was on the DIYsolar forum... the bad gs reviews that i had observed....
rayjunglepower cardboard envelop scam???
eBay is refunding one order now as the seller of powerjack >>>> rayjunglepower did not provide tracking >>> just disappeared when since May 18th, 2022,,,, the cardboard envelop scam did not work...
I put in a complaint with my discover cc so that should take care of another missing order from PowerJack's >>>RayJungle Power
one more missing but I contacted the Mastercard on that one also...
will PowerJack rip off Genetry Solar??? something obviously is wrong with the PowerJack sales team and Jack does not reply via eBay or Skype.... give them a bunch of money and wait 4 months for nothing???
hope they don't lose their hind end on the duds...
the 12k with MPPT is available via two different inverter manufacture companies >>> Sungold power and Sigineer both have them in a LF inverter and have had for quite some time...

I was thinking the same . Will Jack raise the maufactoring cost and shipping cost to GS so GS can not compete with the PJ 30000 watts inverter ??
hope they don't lose their hind end on the duds.. NO actually PJ in China send you the cardboard envelope so you will get your money back and PJ can now sell your 30000 watts inverter for 5000 dollars and make even more money . Seller rayjunglepower account will automatically be close by ebay but David has other ebay seller account control by PJ in China .

I will likely look at a Sigineer or Sungold Power or Yiyen inverter with the copper transformer,,,they are available in 12k 15k and 18k versions,,, there is a 12k with MPPT for $2599 delivered on the internet....likely better than powerjack anyway.....
and yes, powerjack just relabels and sells under a different brand via a new seller on eBay,,,,,.heck of a business model....
their VIP customer statement and seller's claiming they quit has got to be the worst....
perhaps gs will have to buy from a USA seller....to get their gs12 type inverter....or a more reputable vender than powerjack???? or take the gamble with >>>>??????
not real concerned with MPPT as I already have that done as separate components....don't need WIFI either but I am considering setting up my own server vs using any cloud server....I have several dell i7 desktop computers for that...
once the cc was alerted and processed the refund then eBay closed the discover card case,,,, eBay is not good for getting your moneyback either and is a very impersonal system essentially impossible to talk to a real person through the eBay system when problems with scammers begin...do not trust eBay to get your money back....i had to argue to get my money back on a chainsaw that was missing parts which I sent back to the seller...eBay closed the case and would not refund the money,,,cc could not help without proper tracking of the item which I did not have,,,,finally the seller sent me the money back as I had emailed him when i sent it back ((( got lucky 5 months later on that ebay fiasco....)))
still no replies of any sort from "rayjunglepower" >>>>the powerjack eBay seller or from jack via skype ((((POWERJACK-JACK))))...I think they try to lead you along long enough that you can no longer get your money back....eBay is just another money machine,,,
good thing the credit card has protection for the consumers,,,,although i think i may start reading the small print protections>>>get out the reading glasses....
have a great day all,,,,,😎

And my point exactly with those units, "12k with MPPT." If you look at the print and do the math, you will find that the "included MPPT" is so undersized as to be nearly useless.
- Sungold Power: 80A MPPT * 48v = 3.84kw. On a 12kw inverter?
- Sigineer's a tad better: 120A MPPT * 48v = 5.76kw. Still less than half of the inverter's wattage rating.
So as I've said elsewhere, you still have to buy MPPT chargers in order to be able to continuously run full power in the sunshine...and by using the "included MPPT", you will have 2 different types of MPPTs on the system that might fight with each other. (I speak from experience.) You're much better off with just a single type of MPPT.

There are no domestically manufactured LF inverters to my knowledge. Simple reason: nobody wants to pay the U.S. manufacturing costs.

Doesn't happen that way. We contract them to build the inverters--but in each case have paid them a percentage of the total bill for them to ship the units...and then pay the bill off later.

Helen was more customer service than sales...so she got all the complaints. Can't blame her.

Very long shipping time...yes, that did happen. Factors outside of our control...including the fact that it took LONGER for that first shipment to transit the U.S. than it did to cross the ocean from China. (Let's not mention the "funny stupid" nonsense from the U.S. freight carrier saying they'd delivered the goods when they really hadn't.)
Loud fans...yes, I am quite aware of that. But if you look at reviews on the other Chinese LF inverter offers, you'll find similar comments.

If any off-grid inverter is made in the USA to connect L1 N L2 the powerful utility will do all they can to stop production and sale . Only inverter made in the USA are 1000 vdc grid-tie made for the utility . I am lucky that China make inverter that the utility can not stop me from using .

well ,you will be glad you avoid the cardboard mailer via eBay scam from them, i paid in full to have them disappear as many others did in the last month...via the i sent a tracked letter to show it as delivered on eBay scam...why would powerjack allow their product sales team to do that to their customers???
the MPPT is not needed and would add to the value of the inverter but i do not need that part.
the fan noise would be the best reason to put the inverter equipment in a separate building away from the living quarters for sure...along with an increased safety factor by putting the equipment in a properly design electrical room that is climate controlled...
i put my equipment in a separate outdoor solar power shed for safety reasons to keep it away from the small curious children and others...
such as furry critters some allow in their house(not in my house) they have their place outside in the barn
Helen was more customer service than sales...so she got all the complaints. Can't blame her.
It is difficult as when Helen accept my low offer from her ebay seller account for the 20kw inverter last year and PJ in China refunded my paypal account without telling ebay or Helen the order was cancelled . Ebay send me I an email a month later how I like the 20kw PJ inverter that I never got . I am sure PJ in China sold it for over 1500 dollars . This happen to David also for a 20kw PJ inverter that I thought I got for a low price but was also refunded by PJ in China .
yes anything made in the USA will cost more than made in China things.... that is for sure....
cheaper is not necessarily better,,, not necessarily worse....time will determine the quality and reliability of almost all products when used under load for the long haul...... but then again (in the USA) you can not get slave labor for 2 bits an hour or so as the communist countries can ....
i do note that the copper transformers are rated at higher surge capacities and also have less fans and other components... they all seem to use an H-type transformer....vs the round toroidal transformer powerjack is selling...
the heat is seemingly less of a problem in their design.... but I have yet to use one of them.... the H-style LF inverters from sigineer or sungold power or yiyen...so they may have other issues....
the metal quality of essentially any made in china tool is not there....
for me ... I like to buy quality made in USA tools or German tools for the most part and often hate any "el cheapo" china poor quality tool I have ever bought... the fit and finish and durability is not there in the "el cheapo" copycat garbage...
they likely do not properly harden it ior put in and allow too many impurities...
so one would have to wonder about their quality control or perhaps sell it and let it break so they can sell another one later with a different brand name is the china way to sell more junk....🤔🤔🤔

Copper vs aluminum doesn't make the slightest difference in surge ratings, cooling requirements or usage of "other components."
The only differences between copper vs aluminum are...
- amount of wire required for the desired power rating (about 38% more for aluminum due to electrical resistance)
- cost (aluminum is at least 1/2 the cost of copper)
- weight (aluminum is 1/3 the weight of copper)
An E-core transformer is much easier to wind and mount--that's why it's more commonly used.
A toroid transformer electrically is much better to work with--but requires special winding equipment, and is very difficult to mount to a chassis.
Like I've said...I have yet to see a proper full load test on a Yiyen-based inverter (Sungold Power, Aims, Sigineer, GroWatt, etc., etc.) Nobody seems to know if they're actually capable of sustaining the full rated output 24/7.
I think battery capacity for most people stop a 24/7 full load test on the YouTube reviews of the large 12k or 12k plus sized Yiyen based inverters.. Sungold Power, Sigineer, etc...
Aims brand seem to be more expensive ,and growatt seems to have other issues so kind of avoiding both of those...at the moment..
maybe I will splurge and try one out ( a Sungold power, or Sigineer, or Yiyen) after the PowerJack cardboard mailer eBay scam fiasco is ended...and do a load test on it....not sure if I could do it either, that much power 24/7 have to use a lot of electric stuff plus .....
all the you tube videos I have seen have not demonstrated heavy load capability 24/7 on any inverter of 12k size under long term load.... likely due to battery capacity not available.... to run a 12k inverter at full load capacity 24/7...
only short duration load test videos... is all I have seen...
more research needed 1st...
yes aluminum is cheaper and weighs less,,, that is why it is used but has more resistance so requires more thicker aluminum to get the same/similar capacity....
the copper charts show copper to have a lot higher heat tolerance than aluminum...and thus smaller winding requirements with copper transformers.... but still weight is one of the main reason aluminum is used for big transmission wires (of course price was also an issue) copper is very spendy at the moment.....
maybe the heat tolerance of copper is the reason Yiyen based transformers have less air cooling of their copper based transformers??? (Sungold Power, Sigineer, Yiyen, etc) in their LF inverters???
yes aluminum is cheaper and weighs less,,, that is why it is used but has more resistance so requires more thicker aluminum to get the same/similar capacity....
Or maybe they have less cooling because nobody tests them to nameplate??

Strangely enough not a single reviewer on YT has done a hard test of any of them. Even those that have the technical nous to hook up a scope and show what is actually coming out of them under high load have not done it. That tells me everything there is to know about the alleged independence of those reviewers...
