Messages we were getting was the inverter was about ready to blow, and the battery stack was getting hot.

Total time pressure!

What's the solution?

(Narcoleptic Buddah, Munnin...you have the answers, right? I'm a liar, fiction writer, right...what's the gawd dammed solution, smart guys???) How would I know this, if I didn't live it every day??? So, what is the solution...smart guys????


Sounds like it has to be a phasing problem. Seems like something like that would have to be true in order for things to be heating up.

Have you tried unplugging it and plugging it back in?

You’re getting 208 between hot and ground ? How is that possible ? 208 between phases yes . A 208 three phase is 3 - 120 hot conductors . Black red and blue ? What am I not getting here lol?
Somethings loose , something is starting to overload . Your wires burnt up . Your breaker doesn’t trip . I mean I’m not there . Do you want me to come there and fix it for you lol . Check your c phase tightness . Lugs aren’t rated . Well let me know, this thread was great , hopefully you didn’t fall asleep and maybe can answer this time tonight before I go to bed , stay safe .I’m playing with you , this is how my old boss would be like .

Stop. 208 is not three phase, it's single phase double hot leg.

If you have 3 hot legs for 208 your electrician didn't do right.


208 is normal for 3 phase.

No. 208 is not 3 phase. But feel free to correct me.

Yes 208 is three phase . If you have a 3 phase panel you take 2 or 3 -120 volt conductors to get 208
In a house it’s single phase so you get 120/240. 3 phase is 120/208 and 277/480 . You don’t get double the voltage because a 3 phase . So there’s your correction

208 to ground is not normal on a 208/120 volt system.

How is it 3 phase? With 3 phase you are dealing with 3 hot legs that are phase shifted.
Your words do not make it so.
Deny ignorance and educate yourself.

ETA:
In a house you deal with 208 or 240 for such thing like your dryer. Which is still single phase. This is literally my job with given certifications.This is not the sword to die on. I like FCD, but I'm not going to allow incorrect info to be out there. Deny ignorance.

208 three phase is generally used in commercial applications for lighting and lighter loads, any of the 3 legs to ground gives you 110, any leg to leg gives 208.

Your thinking of what is commonly thought of as 220, which is 2 single phase 110 lines. Or in actuality 2 120 lines making 240. Typically household wiring.

480 three phase is generally heavier industry, and is comprised of three legs of 277, each leg to leg gives 480.

Those are the 3 more common types of services in the US

This is a three phase system and 208 is normal.

I can help you prove yourself wrong.
Google search this: 1/2 hp 208 volt 3 phase 56 C electric motor.
You will get hits, with prices, for exactly that item.
If 208 three phase doesn't exist, why do they make motors that are three phase 208 v?

Your wiki link describes perfectly what 208 3 phase is.

208y/120 is the term for it. And yes, it's very much 3 phase power

I explained it to you in my first two sentences that a moron could understand it . 2 or 3 hot 120 wires makes 208 . Well you are an idiot , I already cleaned it all up for you . I wouldn’t let you touch a god damn thing in my house electrically . Maybe put a cover plate on lol . Honestly read through my stuff . What homeowner has 3 phase power ? Maybe a few but not too many have 208 I guarantee you that . Are you a master electrician who owns an electrical contracting business or something ?

Because people are stupid and do not understand what they talk about?
With the motors you are talking about there is a single phase or 3 phase option due to wiring. That's normal.
The 3 phase option is not 208.

So you install dryers lol ? Not an electrical contractor then? Just read through my last 4 messages or so and if you’re confused or want to argue anything let me know . I’d love to get this figured out with you so you can understand.

Wow.
You didn't even do the search.
You can buy electric motors that have a rating tag that says 208 volt / 3 Phase.
To run a three phase motor, you need three phase power.
You have been talking crap here.

I wouldn't ask to touch a thing in your house.
I have been a theatrical electrician with my business dealing with single phase and 3 phase electrical.
208 is single phase.

Parasitic oscillation? AC operates at a freq filter capacitors typically prevent feedback from occurring but have seen where oscillators can be so far off that it lights fluorescent lights while they are off.

This right here is comedy gold for a guy who’s been dealing with electricity for 18 years . It’s single phase double hot leg lmao hahahaha , what is this hahaha . 3 hot 120 legs is 208 volts in a 3 phases system . If you’re too ignorant then whatever but I’ve been trying to explain this to you and you’re absolutely not getting it . So just please ask away

Sounds like you got a bad neutral. You will still get the right voltages phase to ground but if you lost the neutral back to the source you wont have a balanced load and consistent voltage. Also 200 degrees isnt very hot for lugs.
