I've had a Champion 3500/4000 watt for years, and it's quiet, reliable, and economical. Relatively clean, too. But it isn't sine wave output! Mine is a clone of a Honda, as probably is this one. I may look into this one.

Yeah, 7kW generator is probably not enough. Probably need at least 15kW generator. Since the battery is 24kWh, I'm thinking it could charge the battery in less than 2 hours or have enough juice to drive at 60 mph or less.camasleaf said:...I believe the car will take up to 30kW while driving. ...

I have a 7/9K genset of the same mfr, and have used it to charge my leaf through a Juicebox EVSE once. It is bulky, noisy and it weighs over 200 lbs. My purpose for the generator is for power outages, but I have considered trailer mounting it. Biggest problem I see is that it goes through 3 gallons of gas or 10lbs propane to charge 4 hours for ~75 miles of driving using it to charge via L-2. Aside from a one-time one-way trip to transport the car, I couldn't justify the expense over renting an ICE. A smaller, lower output genset (say 3/4k) could be carried in the trunk with an EVSEupgrade, and used during a stop to feed just enough juice to reach a grid tied EVSE in dire circumstances, and be worth the 1 gal of fuel for 25 miles or so. This would be less expensive to purchase, and not require a trailer, but does still leave you sitting somewhere while it runs. To get mobile go juice, adding the Enginer pack (not sure if it works with 2013 and up), or the Ingineer style trailer, it would be pretty pricey considering what you gain for the dollar. Then look at whether your insurance will cover damage to it should an accident happen.DanCar said:http://www.costco.com/Champion-7000W-Running--9000W-Peak-DUEL-FUEL-Generator-wElectric-Start.product.100112008.html" onclick="window.open(this.href);return false;

pchilds said:Generators put out a sine wave. Cheap inverters put out a square or modified sine wave. With cheap generators you will get a sine wave, but the voltage and frequency may very out of utility specs, if you have big changes in load. If you are charging only an EV the load should be steady until above 90% charge. Costco has the Champion 7kW for $599 on sale. I am still leaning toward the diesel generator, I posted earlier in this thread.
