Backup Generator

12K Kubota is 4 cyc.

yea ok, but it doesn't explain how the isuzu is doing it with 3 cyl and is almost identical to the 9.8k kubota

It’s not uncommon for those Kubotas to run 70-80,000 hours and 50,000 would be typical. Longest I’ve seen an Isuzu run is about 40,000 and 30,000 is typical (which is still pretty good). Either one would be excellent for home use but parts are a little easier to get for the Kubotas.

There are lots of both of these engines running continuously on mountain tops all over western Canada and they are both great engines. Kubota is more conservative in their ratings in favour of longevity.

ok but can you explain the fuel usage?

Bigger engine running one more piston and crank journal, bigger fan, possibly higher oil pressure will have some impact. Plus you are taking their numbers as gospel but it could be they used bare engine numbers gross on one and net on the other or engine hp/hr vs kwh from the alternator and we don’t know if all other factors were the same like fuel btu rating, elevation etc.

It’s not possible for two similar engines to be that different in efficiency so either take it with a grain of salt or ask for details of how they got their numbers. If you want to do like for like comparison get the engine model numbers and pull the manufacturers data sheets with the EPA ratings. They will have an accurate value for the bare engines using standardized defined test parameters.

A little silly to worry or argue about longevity of a back up generator. I put about 40-80 hours a year on mine. Longest expected outage would be 100-150 hours. If one is good for 30,000 hrs and the better one goes for 50,000 hrs....who cares? If I live another 30 years, a 3000 hr unit will never wear out.

At 80 hours a year, a 50,000 hour generator will yield you 625 years. Eat healthy and exercise :thumbsup:

Could not have said it better myself .

Picked up the generator at the Sacramento Fedex freight terminal today. That is not the pallet it was shipped on. The original pallet was broken into splinters and the cardboard wrapper was ripped apart. Amazingly not a scratch on the machine. Three Fedex warehouse guys spent 40 minutes getting the machine off the destroyed pallet and onto the new one so it could be loaded safely in the trailer. All is well that ends well.

This will have to live in my garage for a while, I have not started to build the enclosure yet. The steady rains seem to be over now so should be able to get going.

Sweet, did it come with an exhaust ?

BTW I called CMD to get shipping cost to Detroit,, $488.00 so $500 for you not so bad.
