1500W AC inverter in 23MY Prime

Looks sinusoidal enough for government work. (And like a ✕10 probe is being used.) What more are you wanting to know?

 

Do you have a label or something in the car's owners' manual that says what the max load is?

 

I suspect if that's the rating they give it, it's good for that much.

 

Do AI chatbots now sign up for their own forum accounts?

 

Looked like it at another forum I visit.

 

Well, at the end of the day, 120 VAC inverters by now are pretty much commodity items. They do what they're supposed to do, and perform to their ratings.

With an output as sinusoidal as your 'scope shows, there aren't likely to be any devices that would have any problem with it. If you keep under the rating advertised for it, it is likely to just do its job.

Maybe the only question that leaves unanswered is your "near max load for any period of time" question. And I don't have an answer for that. But, did you see anything in the manual that said "intermittent" or suggested a time limit?

 

I don't see anything in the (EU) manual even hinting at a time limit - just lots of talk about ensuring the total stays below 1500 W and that it might not work if you try to exceed it. I get the strong impression it's 1500 W continuous.

I liked some of the actual warnings:

In situations such as the following, do not use an electric device while driving [...]

* When a device is likely to cause burns, such as a toaster, microwave, electric heater, electric kettle, coffee maker, etc.

* When a device is likely to fall under the pedals and prevent the brake pedal from being depressed, such as a hair dryer, AC adapter, mouse, etc.​

 

Those have probably happened at some time for there to be warnings.

 

Slightly off-topic, but my favorite car warning was for my Gen1 Prius, roughly paraphrasing:
- The electric windows have a safety feature to stop the window closing if there is an obstruction such as a neck.
- DO NOT TEST THIS FEATURE WITH YOUR NECK.

Yea, kinda scared that text was put in there because someone did....

So, I used and hairdryer with a two power switch. I was worming glue on some add-ons to stitch in the car. I used the first position for a while, then changed to the highest one for a little bit and the inverter cut off power for some time. Didn't work even at low power (I went inside the house to try the dryer with a normal outlet- here in Europe 220 volt - and it worked). Returned in the car and the dryer was also working, but I kept it at the lower power for finishing the job. No power rating on the dryer, but it isn't a big one! So the inverter has a switch limiting power, auto resetting after some time. Regards
