I second the Outback power quality. We built a mobile medical lab that has Xray, ultrasound and other sensitive lab electronics. A 120kWh Li-ion battery package with 8 Outback 3.6kW stacked inverters @ 48 volts has been operating almost weekly for over 3 years.
Run from Samlex. We were burned SO many times with poor quality inverters and worthless dealer support. If you want high quality, low cost, look at GoPower industrial models made by Cotek. Many sold, none come back. Able to start heavy loads like air compressors and circular saws.

I had sunpower positive grounded arrays, AC-DC Coupled arrays. I had a guy use SMA and had all kinds of issues, mainly operator error. We did a full trailer, green room and light bars, powered drop down doors, but it was a little big.

Traditionally we've always used Exeltech, as they've had the cleanest output, with background buzz on tube amps being lower than grid power. Modsine were horrible, Old Trace SWs were pretty intolerable, Magnum's were usable, but still noticeably more buzz than grid. I think THD is roughly associated with the background buzz, but there might be certain harmonics that are particularly problematic. I haven't gotten into looking at the separate harmonics relative to what induces the most noise in these old vacuum tube circuits. This is a 48 v application that also needs a built in charger with transfer switching. Exeltech does not appear to have anything in that department. Any other choices? How are Samlex?
