What you have are two 5 k generators. Unless they are synchonous generators or you are making DC with sycronous inverters. 5 k will go a long way to power your aveage home providing you use the power wisely, i.e. alternating useage, freezer for three hours every six hours fridge on off hours, no 25,000 btu A/C units etc. having two units his good though. It allows you to alternate between units and keep them in good running condition.

I think I may just need a consultation. No, everything that has been said has been helpful, and you’re right I am thinking I can get away with a 10kw diesel. Now I just need to know where to find one cheep.

I don't want to be a pain (honestly), but however long you can run 10kW on X gallons of fuel, you can run a 5kW ~twice as long. Less (fuel consumption) under emergency circumstances is always going to be better.

I'm surprised no one has mentioned Lister-style generators. A very old, reliable design. See the Cool Tools write-up for additional information. There are one and multi-cylinder versions that produce from 5kW and 20kW, with your choice of single and three phase generation; most turn around 800 RPM and cost less than $2,000. Some even offer electrical welder options! All are quiet and fuel efficient, and most are multi-fuel (wvo).

The largest drawback is that they aren't portalbe and they're quite heavy--larger models are over 2,000 pounds.
