If you are referring to 240V AC, then in the US we do use 240V, altho it's split phase. Most large electric appliances use 240V (dryer, water heater, oven, etc). But I'm going to assume you already know that and was wondering about 240V on a single line.
Most of the inverters that are discussed here on the forums are 240V AC single line version. And unfortunately, the large ones that have decent prices don't support 240V split phase (2 x 120V legs). There are a few, though. So that's good.
If you did get the single phase 240V inverter and needed the split phase, the only way to really do it, with that inverter, is to use a 1:1 transformer with a center tap (this provides Neutral). There was someone on here who got a transformer, but I don't remember who it was. But I think the price they got it at was about how much it'd cost if you were to build one (tho, the unit was bought off eBay, if I remember correctly). Maybe someone else can chime in and say who it was with the transformer.

Thanks for answering that Korishan. I did get my inverter in. I have three packs left to weld, and I'm debating with myself about what fuses to get. I won't hook this up without fuses. I started a discussion on Facebook about it and I know more or less what I'm getting. I've also been trying to think of a mounting design for my situation. I've almost got it figured out and I will share what I end up doing. After I get the battery in place I'll start looking at how I'm going to hook up my two solar panels that I found for super cheap and made frames for. This is a picture I took before I painted it. The frames are actually white.



Here's a quick video showing how I use the Sunko 787A+. It's been a long learning process, but I think I nailed it. it's a usable welder and cheap. I don't know how to make the video show up with a thumbnail or anything like that. Many thanks to my daughter Caitlyn! She was my cameragirl.

Fixed the link for ya Wink

To do this, take the link you posted earlier: https://www.youtube.com/watch?v=rL-cVmCb...e=youtu.be Remove everything before the = sign, and the & and after. The encapsulate that in the [ youtube ] [ /youtube ] tags.
The code will look like this:

Sub'd, btw Wink

Good work on figuring out what caused the spot welder to not function to its capabilities. A little extra tightening can go a long way with electrical connections.

I finished all the busbars and started lining up the packs next to each other and realized I needed to do half the busbars over. They need to be put on opposite of each other because my white wrap is only on one side of the packs. I decided to redo the 5 packs that had the bad busbar, corroded copper, and one more. One busbar I accidentally put on backwards, but as it turns out, I need half of them backwards. When building your wall, take a second and see how everything will fit together. Maybe it will save you some time.

I'll tell my daughter that. She will be pleased. lol. She told me that when I said "don't hate" at the beginning of the video, she almost busted out laughing. hahaha.

your coper busbar look like many corosion. you shoud use new one, it will be more easy to solder

You were absolutely correct. I replaced it. All my busbars look great now.

For me it looks like a good and clean solution to spot weld the fuses, compared with soldering.

Any input on this? Pros and Cons?
There is an urgent need to stop subsidizing the fossil fuel industry, dramatically reduce wasted energy, and significantly shift our power supplies from oil, coal, and natural gas to wind, solar, geothermal, and other renewable energy sources.
