1500W 120V AC outlet

My Prime SE has two outlets - one in the back seat leg area, and another in the trunk. I have not tried running a fridge from it but would be surprised if it didn't work.

 

I checked the output of mine with an oscilloscope and found that it has a very nice and clean output. The total output through both of the outlets is limited to 1500 watts. The inverter is powered by the traction battery, so it should run for quite a while without the need to start the engine.

I have other generators so I don't really need the 120V supply most of the time. It might be handy in other locations.

 

I would be interested in installing that inverter. Can I buy the system to integrate into a 2020 Prius L Eco? The use of the HV traction battery makes it particularly attractive for use in power outages.

 

My 2024 Prime SE has the two outlets. I’ve tested with a heat gun up to about 1300W for 5-10 min. With no issues. My plan is to run my refrigerator (listed with “3.2 A surge”— I’m assuming at compressor startup) plus a few other low wattage items during an outage. Not listed on my Monroney sticker, but it was mentioned on the dealer website.

Edited to add: I also tested a small heater rated for 1500W for 30 minutes with no issues. (Measured wattage draw was less, maybe 1400W IIRC.)

 

After a quick glance at the 2024 Prius Prime Owners Manual....It seems the Traction Battery is 266 Volts. The 2020 Traction Battery is around 207 Volt....so the AC inverter won't work.

 

@Hipparchus: I'm not sure how to post a link to a thread, but search for "1500W AC inverter in 23MY Prime" and there is a thread where I did some tinkering. I got off on a tangent about GFCI not working, but at the end is the testing under load with a scope looking at waveforms.

 

If you have it open in another tab, you can post a link the same way you'd post one to anything else on the web.

1500W AC inverter in 23MY Prime | PriusChat

 

Plus the inverter in the Prime is actually part of the HV charger. (I looked into it a bit for my 2023 HEV.)

 

The 1500W 120VAC inverter is also part of an option package in the RAV4 Prime. Still being a RAV4 newbie, so far I've tested it only briefly to confirm that it would run the garage freezer during a power outage. The next test will include the kitchen fridge. And have used it numerous times to run boot warmers from home and lodgings to the ski hill, though those warmers are of such low power that a small inverter running from an ordinary 12V outlet easily handles that job.

Though when considering units lacking this option, I was unable to find any indication of it being available separately as a kit.

The 2020 Prime Owners Manual lists a nominal voltage of 351.5 V (see page 721).

Different voltages don't necessarily mean the inverter isn't interchangeable. These devices often have a decently wide input voltage range, so a specification review is needed.

 

No, the inverter is only in the Primes. I was interested in adding an AC plug, so I looked at the wiring diagrams to see how it was wired in on the Primes. Once I saw it came from the HV charger, I knew any idea of easily adding a big(1000W+) inverter was dead. I'm using a little 175W inverter plugged into the 12V dash plug for the rare situation when I need one. If I ever have the need for more, I'll add a hard wired one into the cargo area off the battery.

 

I read that a 1500W 120 VAC inverter option was available for 2020 Prius at some trim level.....so I haven't completely given up hope.

 

An inverter providing the same 1500W output is present in Japanese non-PHEVs. Although I don't know about the output compatibility for the US if you ordered the Japanese parts. 100V there, don't know if that's okay for USA. (And 50Hz by default, dealer switchable to 60Hz.)

(And just going to check the manuals, I see that there are new Japanese manuals for March 2024 production onwards. Haven't spotted a difference yet, aside from changes to some information URLs)

 

For people interested in that option, we have a thread:

As far as we can ascertain, they're standard equipment on all US Prime trims. Don't think anyone's seen one without them. Only potential catch is that as they've failed to mention it on the equipment list, you wouldn't have any recourse if they suddenly decided to stop fitting them.

 

It is not listed on the sticker, and neither are a lot of the features of the car. I don’t think it’s listed on the specifications section on the website either.
