For what it’s worth, we have an inverter from CE+T which was installed by our low voltage contractor. https://www.cet-america.com/en/
It does have network monitoring and management. It works great, but has more knobs than most of us are ever going to need. Ours is a 2U unit with 2 inverter modules. You can wire it up as either a 2+0 with two 120V phases on a shared neutral, or as a 1+1 with single 120V circuit. It’s not for the faint hearted…..you actually have to configure the frequency and phase of each module. On my first pass I had it wired in 2+0 and hadn’t set the phases 180 degrees apart like I was supposed to. Each circuit tested fine individually, but when I plugged equipment into both outlets I fried one of the inverter modules. Whoops. I assume you could get a bigger chassis for 3 modules and configure it for 3 phase if you wanted to. If I was picking out the equipment, I’d probably get something simple and single phase and then just get two of them if I needed redundancy.

I asked and got: Our PST series is fully isolated from input to output and can work with -48vdc.

We are in a Frontier CO and having a hard time finding -48vDC powered devices, so looking to just produce 120 vAC so we can just use standard power supplies for them. Primarily, we need to power a VDSL modem (so like 5 - 10 watts), but having a bit more would be nice for convenience. House power isn't always convenient, so it would be a good place to plug in laptops when in there working. ----- Mike Hammett <http://www.ics-il.com/> Intelligent Computing Solutions <https://www.facebook.com/ICSIL> <https://plus.google.com/+IntelligentComputingSolutionsDeKalb> <https://www.linkedin.com/company/intelligent-computing-solutions> <https://twitter.com/ICSIL> <http://www.midwest-ix.com/> Midwest Internet Exchange <https://www.facebook.com/mdwestix> <https://www.linkedin.com/company/midwest-internet-exchange> <https://twitter.com/mdwestix> <http://www.thebrotherswisp.com/> The Brothers WISP <https://www.facebook.com/thebrotherswisp> <https://www.youtube.com/channel/UCXSdfxQv7SpoRQYNyLwntZg> -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
