Here's one place selling it: https://solarconduit.com/shop/generator-start-control-module-gscm.html
You can get a generic programmable controller like an Omron Zen cheaper, but this controller might eliminate the need for some of the relays you'd need with a PLC. You'd still need things like an output contactor on a generator not designed for automatic control. Also, this controller is looking for the oil pressure and temperature switches to ground an input terminal on fault. They aren't wired that way on the MEP-002A or MEP-003A, for example, so you'd have to figure out a way to make that happen if you wanted the controller to handle those faults for some reason.
Not that you asked, but I prefer doing the job manually so I can wait five minutes or so to let my refrigerators and air conditioners de-pressurize, and so I can check the generator's operation in person on startup. I wrote a procedure for generator startup and shutdown so other family members can run it if I'm away, and they've been practicing.
