i have a Koehler 10,000 w propane genset with an enclosed enclosure. i wired it to a separate indoors panel with a remote manual start switch and a propane on/off valve inside the garage of the house. so all i have to do is turn on the valve below the panel, push the start switch, then switch over to the generator feed after its started. i decided against the automatic transfer switch cause i really dont need the genset running if no one is home. the freezer and fridge will keep just fine till i get home from work. i have a 1500 gal propane tank...so should run for some time in an emergency. i have a 5000 sf home and this unit will handle all the lighting loads, microwave, refer and freezer, ignitions for furnace and water heaters, and tv/entertainment system. we lose power alot during the winter months, so its real nice to have this system. mind you, 2 years ago we had a power outage for 2 days during xmas time. the whole area was dark cept my house. even my xmas lights were on. my next door neighbor said he hates me (haha). i told them to come on over.
