Bob, this is a really fantastic write up. I’ve been looking for a 2017 limited platinum Highlander to go camping in and the inverter idea is great.
Do you mind sharing some of your pictures of this setup, and perhaps some instructions on what you bought and how you set this up? Is your inverter bolted to the car or is it unsecured while moving? I’d like to see where the cable comes out from the 12v to the inverter in the 2017-2019 highlander for instance, what wiring you used, any fuses, amp limits, etc .
Also, I though the 2017-2019 max amp rating was 150A. Does it say on the 12V battery what it is?
Another thought - since you have the hybrid why not just sleep in it versus the trailer since the highlander seats fold flat - and just use the Highlander built in AC!
When you say “You would have to assure that the hybrid system was in the On condition before turning it on and remember to turn it off before shutting down the hybrid system.“
What would happen if you forget to turn it off? Does it just drain the 12V battery? Can you run an on/off switch from the rear cargo 12v battery inverter to the driver seat with that inverter you recommended or do you go have to go back to the trunk every time? Also , on the ‘14-‘19 Highlander - the inverter you recommended was 2000w - what’s the max watts for the ‘14-‘19?
Also, what are quick disconnect plugs for and do?
BTW, I am 100% sure that the 2020 Highlander limited and platinum 1500W are running off the 12V. It’s not coming from the high voltage traction battery. It’s the same setup as the Prius. There’s no other way to meaningfully do it. Toyota justdid thesame thing Bob suggested but in a more streamlined and clean way rather than the inverter sticking out but that costs an extra $1500. No thanks; I’ll buy a 3 year old Highlander hybrid platinum certified used for $20k off versus a brand new ‘20 Highlander that’s $50k and doesn’t have tow Package o rear folding window.
Bob, if you can link us all the parts you bought, perhaps a write up, or even a YouTube video showing how you wired this it would be really appreciated. I’d like to see where your inverter is relative to the 12V battery. You’re the first person on the internet who has described using an inverter on a hybrid Highlander on the 2014-2019 generation and it would help a lot of future campers.
To BOB and OTHERS:
1.The following YouTuber is reporting on his experimenting with using the 1500 watt outlet to run his AC on the 2021 Sienna (same hybrid setup as the Highlander) while car camping and describes his observations on this strange kind of constant engine re-starting interval and run time of the engine; and then switch to hybrid battery to power the AC for a constant time interval, that is regardless of the temperature inside or outside. I may have misunderstood him on the above. I think he is also not indicating or providing info on at what interval the compressor is on and off as if the programming is disregarding how often the compressor is cycling. He gives his assumptive explanations on why and reason's programming. What do you think of the facts being provided, all the explanations & observation. While you really need to watch the whole video but my summary(including the link) is as follows:
www.youtube.com/watch?v=bngRFxiYagY He tested at 72 or 78 degrees F AC settings while the outside temperature is 85 , blower fan is at 2 bars, and he found the car simply start every 12 minutes, engine ON for 3 minutes ' and 9 minutes off with the hybrid battery powering the A/C, but actually that is independent of the outside or inside temperature. That is programed to top off the hybrid battery to keep the battery in peak readiness for driving rather than the AC because the AC battery can run much longer than that. Also, cannot lock the car while the engine is on A/C.
2.On the 'car cannot be locked', that is a little different from the owner's manual solution that car will not active the auto shutoff after 1 hr. if one locks the door with the door lock switch or with the mechanical key from the outside (ie. open the window, lock, and shut the window).
