I have had my Schneider XW-Pro up and running for over a month now. While I am having issue with trying to make it do "Time of Use" power shifting in an AC coupled on grid setup, I do have to say that for an Off Grid or backup power system, it is a rock solid beast. I have not even come close to pushing it's limits. I loaded it to about 4,100 watts, puling about 80 amps from my battery bank and it was running dead cold and producing a very clean sine wave. The only complaint I have about it as an inverter is it does produce a high pitched noise on top of the expected 60/120 hz hum. I have also pushed it to over 50 amps charging and measured over 95% efficiency based on the measure watts in and watts out. If I was using DC coupled charging, I would have no complaints about the system operation. Their AC coupling works great for a backup system, but the "Time of Use" is broken in software. This will have no effect in an off grid system. The build quality, and the over built design feels like something that will last many years. Nothing like the thin cheap feeling metal on the Chinese mass imported stuff. The XW is actually quite compact, at just 16 inches wide, 23 inches high and 9 inches deep, but it weighs 122 pounds. And a good chunk of that weight is the huge toroid transformer that produces the isolated 120/240 split phase power from the 48 volt DC switching block. This 6,800 watt inverter looks to have a larger transformer core than the Aims 12,000 watt device. We did get it up on the wall plate with 2 people, but we should have had a third.
I am annoyed at Schneider still, about my AC coupling ToU issue, but I can't deny their hardware is well worth their selling price. I managed to catch a discount through Real Good, which is Alt E Store's California location. And they even had a free shipping deal when I ordered mine, which is huge when the pallet came in at over 180 pounds with the gateway and conduit box thrown into the mix. They had to use a lift gate truck to drop it off. And even now without the discount I got, it actually is listed for less than the Aims 12,000 watt. Yes it is "rated" for less than the AIMS, but I bet running them both at 6,000 watts, the Schneider will last longer.
Magnum, Outback, SMA, Victron, and others also make very high quality gear, but this is the one I own and have experience with. If I had more battery, it could run my whole house. Maybe not all the gear in my shop at the same time though.
