A related question - I assume there are Toyota factory service manuals around - a wiring diagram would provide the definitive information regarding my questions. Any pointers to how they can be obtained or found on line?
Thanks

Toyota makes factory documentation available through their TIS (Technical Information System) web site here:
Toyota Technical Information System

It is available by subscription to anyone. For us common folks they charge $20 for two days access.

1) are these receptacles individually fused? In either case, what is the fuse rating?

No.
Theoretically:
P/V = I
1500 Watts / 120 Volts = 12.5 Amps

2) Is each receptacle fed from its own inverter, or does one inverter feed both receptacles?

Only one inverter.

3) is the inverter a pure sine wave inverter? reference to a Toyota doc that specifies it? It is impossible to determine this from a cut away picture shown in this forum.

From the 2022 Owners Manual, page 383:

The following cautions may indicate that the inverter is not entirely voltage or frequency stabilized:

I did this the other day. I have a limited with 1500W ac outlet. So I used that. I have a flat extension cord that let me close the rear hatch. It worked fine for refrigerator and a few smaller loads.
I made the car stay on for longer than an hour by reaching in through back door and locking from the inside driver door switch. I did it this way partially to see if it would work. If you do this, make sure you have your key with you. I could not unlock the car using the fob. I had to use physical key to unlock car again. So, next time I'll just lock it from the outside using the key.
Unfortunately I did not turn off the HVAC in car. So it probably used more gas than was needed. But the benefit was I found I had a nice cool car, so, could probably sleep in the car and stay cool if needed.
I'm not sure how much gas I used. I ran it this way for about 3p

What kind of flat extension cord? What length/AWG? Why did you have to open the car with the key inserted, was the 12V battery drained? Can you elaborate? Thanks.

About 12 foot long, 14 AWG. I would not go smaller than 14 awg if you want to draw the full 1500w.

12 foot was not long enough to reach the house, so I used a 50' 12awg extension in addition. 14awg would probably have been enough, but I already had the 12 awg cord. The regular round extension might have been OK, but I did not want it to get crushed by rear hatch closing. Once inside the house I used a variety of extensions to reach the various appliances.
The car has to be on. Or "ready". to get power to 120v outlet. To have it stay on more than an hour you have to either lock driver door from inside, or, lock door with physical key. Apparently as a security precaution it appears if you lock door using inside switch, you have to unlock with physical key (unless you are inside and use the switch). I'm not sure about that, maybe it was a quirk. The 12v battery will be fine as long as the car is in ready mode - it gets charged by the traction battery and should not go dead.

thanks very much. This flat cable is going on my shopping list. Can you describe how you get out of the car by keeping the car locked from the inside.thanks! xoxoxo Toyota nation!

I pushed the lock button through the back door. Then closed the back door. There is probably a better way. But I have not experimented. Let me know if you find a better way. Thanks.
Honestly, next time I have to do this, I'll likely use the mechanical key to lock the drivers door from the out side. Then I know I have not locked the key inside.

This is an interesting idea that I'd like to try. Thank you!

you are right, the DC-DC converter is what continuously refills the 12v system. in the 2008 highlander hybrid its around 1kw, but i was fairly conservative always when pulling out power, so stayed more around 700-800 watts. a couple of pointers for you... (i manufacture a product that does exactly this, turns a car into a generator, so have significant knowledge in this space) 1) you can do a simple test with any vehicle to see how much power they have engineered it to provide as a baseline. buy a DC clamp amp meter, put it on the 12v battery, switch on the car systems but WITHOUT the engine or hybrid system running, and then switch on all the accessories one by one. on my 08 hihy it gets up to around 70-80 amps. this shows you how much power they have engineered it to sustain safely in order to support all systems and accessories running. 2) if you get a big inverter like 2000-3000 watts just simply to do a test, watch for how much load you can pull on the AC side of the inverter, until the DC side car voltage gets down to 13.3 or 13.4 range. We instruct our users to make sure the DC vehicle voltage always stays above 13.3 volts because that generally indicates the alternator or DC-DC converter is keeping up supplying voltage. 3) I would be careful to not try and max it out continuously for a long time. you never want to risk harming your vehicle systems. Our sweet spot for most vehicles is 1000 watts, with 1500 and 2000 watt models for if your vehicle has the alternator or DC capacity. 4) make sure to use pure copper cable, minimum 4 guage, and ideally as short as possible. our product is 7 feet from battery clamps to the inverter post terminals. 5) above 1000 watts you must use direct bolt on lugs and/or anderson high amp DC quick disconnect plugs to sustain continuous transfer. if you are using clamps it will overheat above 1000 watts. Hope this helps, feel free to ask anything, i'm glad to help with 5-8 years of solid experience in this function of turning your vehicle into a generator.

Thank you for this! I would like to know how to use the hybrid battery system to charge my lithium battery bank on my camper. On a car with an alternator,I would use a dc-dc charger hooked up to the tow vehicle battery. With the hybrid system not having an alternator, how would you achieve the charging?

Search for jflarin posts. He describes how he did it for his trailer. He might not use a lithium battery, so no need for a DC-DC charger, but the concept is the same. Same concept I used to add a 12v power source in the rear. Basically add a relay switched by ignition on, and powered by the the 12v battery.

Trying to work with what I have in the event of a prolonged power outage...

I bought one of these (Duracell Power Station) from Costco awhile back. In the specs/FAQ is states it has an inverter, in addition to being basically a UPS. Could I theoretically connect the rear posts of this to the 12V battery in my HyHy (LE '21) to recharge the SLA battery that's inside this Duracell? I imagine the Duracell will drain faster than it can re-charge, so I'm hoping that's where the vehicle could auto start/stop to recharge the 12V (and in turn, this Duracell)...
