Default Windstorm, over 200,000 without power

Nice little windstorm rolled through the Pacific Northwest yesterday and knocked out power to over 200,000. My whole house UPS kept everything online for about 6 hours, then it was time to fire up one of the gensets!

Batteries keep the heat, lights, fridges etc. going 4-10 hours depending on the time of year, loads and whatnot. It's the whatnots that really determine the actual run time. When the battery bank is around 60% DOD, depth of discharge, the genny comes on and takes over. Runs all the important loads and recharges the big battery.

Whats nice about the big UPS is when refueling or checking the oil nothing goes offline when the genset is shutdown.

Had recently serviced my Onan powered Miller Legend Welder/Generator so it was first up! 18 hours nonstop except for a brief oil level check after 9 hours with no problems. 10 Gal tank typically gets me around 20 hours of run time. 1/2 GPH is what it consumes with average emergency loads.

This Onan powered Miller is rated 5KW@120/240 and a very nice and quiet 1800RPM. Neighbors don't complain if it runs all night, which of course it did...

Cool beans. Glad that was the only "problem" you had.

TJ, how young is that welder? I think I see a microscopic spec of dust on it.

Made in 1988. Rebuilt back in 2009 or so. I'll check on that dust....

This is what it looked like before the rebuild....

TJ, beautiful job on the restoration! Ignore my comment about the dust spot. It was a small smudge spot on my monitor screen.

By the way, late yesterday I sent you a response to your question. Please check your message inbox.

OnanParts a question about your Miller welder/generator. How is the DC welding voltage produced? Do they simply rectify the AC or does the generator have a commutator as well as a set of slip rings?

Nice setup and nice restore!

Mine is similar in that I have a battery bank that would be used at night.
Then my choice of generator the next day.

The generator would power the house, and charge the battery bank back up for the next night.
