Generator Size for Three RV's
Hello, We have a spot on our farm that we would like to setup for three campers. We are wondering if we could buy one generator to power all three. One is a 50 amp with two A/C's Two with 30 a...

Having a Kubota with one the last 12 turn 12.5 KW Katos ever made, I don't know if your accountant's hat is sitting square but you may be looking at 20 - 30 gallons of diesel per day. Run time between oil changes, varies, but I use a C750L Luberfiner soot removal bypass filter and an adapter fitting for a Baldwin B88 oil filter for an 855 Cummins. All done to reduce soot buildup in the oil and maximize runtime between oil changes.
No matter how I run the numbers what you are looking at is going to be insanely expensive/a horrible maintenance-time-eater and a potential land mine in customer relations with RV space renters. It just does not fit.
If your spaces are within reasonable distance a pair of three phase 240 to 600 volt transformers, overhead poles and lines, aluminum conductor, then a Scott Connection transformer on the RV end would be the most cost effective. Set concrete 7 meter poles with vertically oriented insulators 24" spacing. The separate Scott Connection transformers (one tickler) will convert 3 phase to single phase 240, or you'll never balance phase load (school of the hardest generator knocks). I did four multi-RV commercial installations in the Sierra Nevada mountains at summer resorts, including the engineering studies, only the installations were not commercial power but gensets remotely located because of noise and fume isolation. The gensets powered resort stores, and utility services as well.
Running overhead lines, you have to incorporate lightning protection, no matter what the power origin, commercial or private. You have a big job ahead of you.
The Walker Lake project used LPG fuel, one Wisconsin 37.5 HP V-4, with an Onan 15.0 KW backup. Even 30+ years ago, this larger project LPG 24 2-volt cell batteries and twin Trace 5548 inverters consumed more LPG fuel than I would ever care to deal with. The owners were always complaining about fuel usage.
