Actually, it needs to be in READY mode. While ON mode will recharged the battery after it gets mostly discharged, that is hard on the 12V battery and the voltage will be lower than you want for operation of the inverter.

Not likely, since your furnace has a large fan which likely draws significant power. The furnace for our heat pump uses a 30A breaker at 240V (not including the 60A/240V for the electric emergency heaters and the 40A/240V for the outdoor unit). That means my furnace could draw as much as 7 kW. I wouldn't plan on putting more than about a 1 kW load on the LEAF's 12V system.

It looks like the onboard DC-DC is rated to 1700W, so 1.5 kW sustained with brief forays to 2 kW (buffered by the 12v batt) are probably aok.

My current genny is a 700W HarborFright $100 special. Not sure if I want to drop $350 just to double my capacity, and add a big convenience factor.

I guess that depends on what you mean by "furnace"

If it's an air handler type unit as the other posted suggested, then it would depend on the size of the fan.

However, my gas Furnace is gas-hot-water, and it runs the system with no problems at all.

That's a Munchkin 200,000 BTU boiler, and 6 TACO circulator pumps with related controls.

No strain at all.

So to be clear on my understanding, the READY mode, achieved on a 2011 by turning it on without depressing the brake, will power the onboard 12V charger, and maintain the LEAF's 12V battery, and allow for the constant draw of the inverter until the traction DC pack is drawn down to minimums?

Thinking out loud, I have a smaller clip on 12V inverter to 120VAC, that would power some smaller items (LCD lights) in the event of a black out.

It has been my experience, that the car has to be in whatever "mode" you would be in to actually drive the car.
Otherwise......... darkness

A good power inverter is an absolute necessity to make the best use of this rolling powerbrick. But- It makes the most sense to have access to that power in the cabin where the passengers can make good use of it, in addition to having it permanently installed for use on demand.

you are mixing heat pump with gas furnace..gas furnace(in heating mode) only has to run the fan and controls on the electricity while the compressor stays off. other have wondered the same and people measured 5-10 amps of load when the fan is running so I think this set up would have enough capacity to run gas furnace in the heating mode. however I already have 4.5kw generator I bought for $300 in case we have power outage. It has been sitting unopened in the box for 2 years now...

No, that is ON mode. To enter READY mode, you need to press the button while depressing the brake.

Correct. That is READY mode.

Please read my post again. I am talking about the furnace for our heat pump. Just a fan and controls. No compressor or anything else.

Are you drawing 10A from 240V or 120V. If 240V, you may have trouble starting and running that fan. Our fan has a soft-start feature which reduces the start-up load, but many furnace fans may draw significantly more power to start than to run.
