Discovered an issue with the diesel genset. Turned it on and ran it for a few hours, but it was not producing voltage, or at least my inverter was not detecting it. Not sure why, so I'll need to do some investigating on that front.
Hopefully it's a wiring problem I caused, and not that the generator doesn't generate, lol.
Finally dug into this.
As it turns out, I had L1 (black) and L2 (red) switched on the inverter. This was not a problem with the 50a plug to 120v adapter because that adapter bridges the 50a L1 and L2, and the inverter ignores L2 input if it's the same phase as what's on L1. It shouldn't (I don't think anyway) be a problem with 240v across L1+L2, but I wasnt seeing that, so I fixed it as a troubleshooting step. It probably depends on the phase config your provider (or genset) supplies, either 180* or 120* off.
This is how it should be. Those 6ga wires are hard to move.
After fixing that, turned the generator on and it was only producing 120v across L1 and neutral, but I celebrated it producing something
Snooped around the manual and found that the generator can be wired to produce 120v (only), 240v (only) or 120/240v, kinda like how a polyphase electric motor can be rewired.
So, I pulled the genset control apart to get to the generator wiring. This is a Cummins Onan HDKAS genset for reference.
Rewired the generator to the rightmost diagram 120/240v, hooked everything back up and now the genset provides my inverter with 245v. Success!!
One of the reasons why I chose this inverter is because it has an AC pass through port terminal block, meaning I can wire in a 50a 240v outlet that gets power directly from the input terminal block (not inverted or modified at all). That will allow me to run welders and other 240v shop equipment off the motel
Maybe I'll get to the shower and interior finishings soon. I'd like to. We will see. Now that the genset is operational I should service it, so that should come first.
