I really don't need more than 10 kw. And I figured the welder part, being portable would come in handy on the farm at times.

Hate to get over the 4 / 5 grand mark.

Something like my little 250 propane Bobcat would be the most versatile around the farm. Besides stick, and wire feeder welding, I can plug in my plasma torch in it's 10kw 110/240v outlets.

I have a 10kw Onan/ Cummins RV genset like the 4kw one that Grumpy posted with 320 hours that I had set up at the house.

When I get a chance that's going up on EBay. The Miller Propane Welder/ Generator is a better all around choice for me.

New technology will be backup power supply for houses that are like the Tesla powerwall where you always have

a fully charged battery ready to replace your power when needed. No fuel needed and always ready.

An electric car could also be your backup with its large battery storage.

No engine to start and instant response , ideal solution.

What is the installed cost of this ideal solution?

Ok ! Now this is exactly what I'm talking about. Paul the unit I'm looking at is a trailblazer, the question I have , is will it run at idle rpm until it needs to supply a hi amp load ? The trailblazer is a 3600 RPM welder at max load. But throttles down for low output.

There is no ideal solution , and price is to your budget and how critical the backup power is.

Even very critical loads , ie Hospitals , have protocol for energy management in an emergency

and can reduce the load as needed to still maintain their capability to deliver care.

You have to decide what is critical in your household and set your equipment to only power

what is essential with the ability to shed loads if necessary.

The idea of the backup is to able to use the house battery backup and if an electric vehicle is

also there that stored energy as a second source of supply. Tesla and others are working to

make this a seamless transition.

I never noticed if it kicked out of idle under full load. I will definitely check it out next week and let you know.

I don't recall why I picked the Bobcat over the Trailblazer. I think the Trailblazer had an additional contactor and remote tig feature.

I understand the concept, but I have no idea how much that type of setup would cost for an average house. Your answer did not answer my question. If you are not sure, that is fine - I was just curious.

If a person was in an area where power outages only lasted a few hours I would suggest an inverter and battery backup with load shedding capabilities. This is only based on my experience with the 260 lbs of lead acid batteries in our motorhome.

In our old shop I had a 3,000 watt inverter connected to one of our fully charged 3500 lb electric forklift batteries. That was capable of running the stoker, alarm system, and a few security lights for three days. Fork lift battery was around $4,500.

I'm sure someone like Larry can jump in and calculate the battery size required to supply a 10kw load for a 24 hour period.

McGiever where are you ?

Then all you need to know is the length of your worst case power outage. In our home a battery / inverter backup is feasible, but If you are in an area that has power interuptions lasting more than a day or two a backup generator may be your better option.

The perkins looks good . Are they still made in England ? Good price for an 1800 RPM gen.

An unknown... like yesterday when a large truck wiped out the pole and transformer at the end of our road. Impressive fireball as the transformer took a dump. 6 trucks - well someone had to make the coffee. Care and feeding of a 10kw generator means you have to have the right amount of fuel and it could go on for days. Now POH coal heat gives me all the backup I need. I do compromise in that a Champion 1600W $175 TSC special runs the AK 180. I have two Lister CS/6s that I have not looked at for 5 years.

Perkins are the best. However, nothing runs like the super slows. They did have a twin 12 HP up there, I wonder if it is sold.
