What is the rectifier shelf for?
Basically a dual conversion UPS. Will add batteries and inverters, and it will power my server rack. It's a big overkill as my rack only draws like 400w, but I'll be adding my workstations to it too, so that's going to be around 600w+ When power goes out or flickers etc the equipment won't feel a thing because it will be running on inverter the whole time.
This will also allow me to setup a way to transfer to solar. I will eventually automate that based on solar power availability. I wired the rectifier shelf so each rectifier has it's own power cord so I can run partially on solar or fully as the rectifiers basically load share. There's 3 slots but I'll only run on two unless my setup grows beyond that. Each rectifier puts out around 1kw or so.
Had a bit of a janky setup going on to test it over a few days and so far so good. I put it all away for now though since I had to clear that whole area to get ready to drywall. I still need to decide what I want to do as far as DC power distribution goes (bus bars etc) and once I get to that point I can rack it and install it more permanently. I don't have any inverters yet though, that might be my next purchase, as it will technically work even with those 4 batteries, just not for long with any real load. That light bulb was just to put a base load on it, was around 40w and ran for 3 hours on those batteries.
