These have peaked my interest.  Who wants to be the guinea pig lol

nevermind on that one, it's single phase 240v.  On that 12000watt one, it doesn't look to have solar charging.  Think it just does grid charging.

I don't want any charging. I want inverting.

Guess i'm spoiled by my mpp that does it all.  I could just get the pcm60x for charging i suppose.

I have no logical reason to NOT have both in one unit. I just always wanted two separate units. Even if it came with charging, I wouldn't use it. Why? It just sounds like a good idea keeping it separated. It probably helps with heat, but aside from that, my personal preference I guess.

I wouldn't call that a proper review Undecided he didn't do any load testing with measurements or see what it consumed versus charged or outputted. Nor did he take it apart to see how well it was built inside.

he did in later reviews, had a lot of issues. So i searched for sigineer on youtube and that one showed up, looks like the sigineer, but says Aims. You think one is the knock off of the other or are they the same company? Sigineer even commented on the video confirming it was one of their discontinued models.

I got an answer back from their company. They are an OEM manufacture which does not "promote their own brand". They do not have UL certificates but rather they are claiming the meet UL requirements. So as an OEM manufacturer, they sell to brand owners who then take the product and get it UL certified under their own brand name.

This is Franklin from Sigineer Power.
Thx for your inquiry.
We are a professional Chinese OEM manufacturer of Inverter/Charger, DC
to AC Power Inverter with some custom models conforming to UL458 ,
UL1741, ETL or CSA .

Our standard inverter chargers, including the 12KW inverter you
inquired, are without these certificates, as we don't really promote
our own brand.
But we have some "unbranded UL models" which are 100% electrically
compliant with UL458 or UL1741, but without UL sticker and UL
certificate #.
Because they actually passed UL testings and were branded by other customers.
If you , as a business owner, are interested in getting any model
certified under your brand, our experience can help get you pass all
testings in the shortest time.
If you , as an individual, are interested in getting any models with
UL quality, you are welcome to buy our "unbranded UL models"

Should you have any more questions or interest for our products , pls
let me know.


Waiting for your reply.
Your sincerely

And this why several different Company's models look so much alike. But yet, the prices can vary from $50 to $500 just because of the name on the box.

This is also why you can buy "Chinese Knockoffs" that are just as good as the "Name Branded" stuff. It's cuz they are made in the same factory by the same manufacturer.

Probably then why aims inverters look identical, but cost a lot more, must be the UL certification.

So, what we do then, is find out who the manufacturer is (in this case we did), and we buy a bunch of systems from them and resell them on eBay/Banggood and make some $$! Smile

Actually, knowing this information, it makes it a lot easier to recognize that this is a solid unit that could be used in our builds without too much worry that it's going to cause issues. Altho, as mentioned earlier, the wiring does seem a tad small for the current they claim. Maybe there's more wires we can't see in there sharing the load?

They do mention bulk shipping, so it'd be interesting how many in required for "bulk"? Also, I wonder if they'd be willing to send a test unit out to be hammered, slammed, abused, inspected, and pushed to its limits for our benefit.
