because of China, they are way ahead in the solar/battery/energy market. They can now produce in massive scale so the price is extremely competitive. Before some dumbs starting to argue, the batteries in your phone, tablet, watch, and almost all other electronics except US electric cars, are all made in China since day 1. US government won't allow them to officially open a store or sales department here, because they will just destroy all the farking expensive non sense US companies. Like the solar roof system here in US, can cost $20K-$40K easily, and the same system in my grandma's house in China is like 10x cheaper......

Surprised this took so long to show up. If you're buying at least 2 you can use the 10 off codes for a better deal (USDEAL10 and then USAA10). Bought 2 and 2 yesterday for super cheap.

How come? You're buying a Chinese made product from a Chinese retailer, do you think it suddenly turns into a better product if you buy it from Amazon?
The few times I've ordered from them (small electronics) they came way better packaged than anything I've ordered from amazon, not to mention Amazon's customer service is becoming a joke, im still battling an order from 6 months ago where they sent me the wrong item then charged me again because the item I returned wasn't what l ordered. Uh yeah thats the problem.

Thanks for the tip. I already have an anker solix C1000, but looking to expand to solar with inverter, controller and batteries. I've got 2 of the 150AH eco-worthy batteries and looking to complete the system. I think this summer will be a scorcher in South Florida. Just getting my preps in order. Again thanks for responding.
agreed, it's 80 degrees in chicago in april. what climate change? there are still a couple glaciers left.😊

Two in series with the right kind of MC4 to solar input is perfect for nearly all solar "generators". Most are rated for 60V 10A. The larger 3KW version can accept up to 160V.

I've bought 5 3d printers and accessories and some cheap decor/misc stuff on Ali... All better quality than I expected, faster shipping than I expected, and better customer service than I expected... And great prices. Politics aside, it's an alternative to Amazon. Many of the same items for a fraction of the price.
I tried to buy 2 color printers on AliExpress and got scammed both times. The 2nd time AE asked me to prove the package wasn't delivered. The scammer showed them a delivery picture that was clearly the wrong address and the package clearly wasn't a printer. Still, I had to record a conversation with Fedex, upload a ton of pictures and it took over a month to finally get my money back. So, I'm very Leary about buying big ticket items on AE.

If I were you, I would dispute the charge with Paypal and my bank. They have to prove to the bank the printer was delivered as is. Let them deal with my bank.

You can exceed 15A, and the power station will at most pull 15A. You cannot exceed Voltage.
