I'm sorry, my 30kW quote was from an earlier version of the Prius. Here's the latest version.

WRONG. 50 KW Prius : 76HP X 746W/HP = 56.7KW Engine power. Youre going to have to use every bit of that to get 50KW electrical output. It would take a 76HP tractor engine to produce that at 2000rpm.

I think we are mostly on the same page when talking about the output of the hybrid vehicle. Using your formula in reverse while ignoring losses, 50,000 / 746 = 67 HP. Is there some reason that you believe that the 134 HP Prius engine can't develop 67 HP at 2,000 RPM? Thats 50% of its maximum gas engine output.

In reality, you would only need 10 to 15 kW to backup power a house. That's probably less than 20 HP.

You have apparently invented a new page. The EngineHP you initially gave by excerpt/link is 76HP.

The joys of max torque at zero rpm!

Tesla has a house battery, but I think it's more for backup than full-time use with a PV system. But it's a start. Powerwall | The Tesla Home Battery

I don't know if I'll ever own one, but did you know that a Prius or any other hybrid can be used as a standby generator for your house with a simple kit?

Prius has a 30kW generator.

The better ones start and stop the engine as needed to maintain the charge. Quiet too!

My original posted information was for the early version of the Prius with the 30kW motor/generator. My graph so indicated . OTHERS invented a new page quoting the newer 50kW Prius and I responed to their posts. Sorry.

Max torque at zero rpm = zero HP and zero work achieved.

There is a short 530+ message thread over on Priuschat.

From my reading of that thread you would be putting your Prius in danger if you hook up directly to the "traction battery". What almost everyone is doing is running their converters off the 12V battery and drawing up to 5 KW max. I've yet to find any reference where I could relatively easily hook a Prius up to the house and expect to be able to pull 30KW off it so I could run my welder and cook a turkey in my electric oven.
The main advantage of the Prius as a 3 to 5KW generator is that it automatically starts the engine, charges up the traction battery, which charges up the 12V battery, which is hooked to some form of plug out kit.

Basically an autostart generator attached to a battery bank.

/edit
Here's a response to my request for being able to pull even 15KW off a Prius:

With the proper conversion equipment you will be safely maxing 6KW of pure AC power with out incurring in any damage to the Prius.

So although the ENGINE may be rated a XXHP/KW it ain't gonna happen anytime soon.

You mean if it's running or sitting on the side of the road with dead batteries. LOL One thing's for sure, he ain't gonna chase me very far.

Oh, I don't know about that... The top Tesla range is about 300 miles!
