Ive read about folks using the car with an inverter to power apliances
during blackouts, im not interested in warranty issues just a few
facts on operation, I dont own one but am curious.
Does the 12v lead battery start the motor,
Does the traction battery tell the motor when to start because it is
low.
If a load is on the 12v lead battery does the traction battery keep
it charged when motor is off
Why have a 12 v lead battery
Can a 1000w inverter be used safely but only pulling 500 watts
Is cooling components an issue in winter or summer if not driving.
The Auto starts when ON if traction battery is low, and motor shut
off.
Can power, kwh produced be monitored- recorded by the car if
generating for an inverter.
Do many use the car for emergency power
Can it be done safely by someone with experiance with generators,
transfer panels and AC power
What are logical drawbacks and limitations

No. The computer tells the system when to engage the gas engine. The
motor/generators, the planetary gear system, and the engine are all a
big system that's controlled by the computer. When the computer needs
the engine involved, the motor/generators draw energy from the 201v
traction battery and engage the engine.

The Hybrid Synergy Drive is a SYSTEM. You don't turn the motor on and
off. The system manages itself and the energy flow. When the 12v
battery is low, the system lets the traction battery power it. When the
traction battery needs juice, the computer will engage the gasoline
engine as needed.
> Why have a 12 v lead battery
To boot the computer which runs the SYSTEM. Unless and until the
computer is booted up (takes about a second), the relay that allows
power to flow from the traction battery is closed. The traction battery
is a dead lump up to that point.
Consider the Apollo spacecraft: they had a variety of energy sources,
too. No one ever asked why they had a fuel cell when they also had a
rocket engine.

That's not a sentence in English. ????

Do you hook up an inverter to the 12v battery, is it safe to run an
inverter to power other things.

No, you hook it up to the high-voltage traction battery.

I'd like to know what sort of inverter you connect to the HV traction
battery, and how well that works out.
We experience periodic power outages, so I keep a 2.5kW generator with a
few days of stabilized fuel.
However, in my '04 I've installed a much larger 12V battery, plus a
permanent 1.4kW inverter and a switched circuit. There's a permanent
120VAC three-conductor plug as well, and I keep an extension cord handy.
When traveling, that arrangement supports various electrical appliances
and chargers.
It's been valuable at home many times in the past five years. When we
lost power last month, I drove to a needy friend's and plugged in to get
some of his electrical stuff functioning - very satisfactory.
