I live in an old neighborhood with above ground power lines and lots of trees. It’s easy for branches to damage power lines. Last year I got a Cybertruck and Tesla’s Powershare installed at my house. While I’ve used the Powershare and the past, I haven’t had the opportunity to use it for music yet. Attached or the graphs for the total harmonic distortion in and out from my P10. This is theoretically the total harmonic distortion from the Cybertruck’s DC to AC converter. There must be some kind of noise throughout my home power lines because it looks very similar to my grid power total harmonic distortion. I guess next I’ll have to move the system outside to see how it performs directly connected to the truck, but today it’s too hot for that.
I’d refrain from using Power Truck to operate sensitive equipment, especially hign end stereo gear. The power quality may not be up to the task, and the metering on the Power Plant is merely there for entertainment value. Many generators sold today do not provide clean enough power to run sensitive electronics. Not worth the risk IME.
OOF–I’d be concerned about simpletons with bottles of flammable liquids! 
So some of PP’s advantages are more informative than operational? I guess that tracks. Do you have more to say on this?
Also need to be cocerned with the massive amount of EMI gererated by the DC to AC converter.
It will give you a general idea of what is going on and how much improvement is offered, but it is no diagnostic tool. I’d not use it as a power quality measurement device to determine if the power source is safe for sensitive gear.
Fluke makes an excellent device, but is rather pricey for casual use. The TOTL 1770 is effective for 3-phase anaylsis, but lists north of $9k. Possibly a used Fluke 43b, which I have no experience with.
I have done analysis with the 1770 predecessor, but that has been many years ago.
Exactly, and waveform quality. The requirements for an EV motor are considerably different than for audio gear.
Thanks for responding. It is neat to learn a few new things.
Truck is tucked neatly into a garage hidden from the flammable liquids.
The truck is plugged into a Tesla Gateway which feeds power to either the Truck (when grid power is available) or from the Truck to the entire home (when grid power is unavailable) like a big stack of Tesla Powerwall batteries. Could isolate the circuit that the system is on but it isn’t totally straightforward given the configuration. Anyone have one of those fluke testers and interest in this topic? I’d be happy to supply the truck for testing.
You may be able to rent the tester. Then there is knowing how to use it.
Better yet, track down an industrial electrician in your area. They may be able to either do it or recommend some one that can. Your local electric utility may be able to provide references as well.
