Delta Pro over voltage shutoff smoke

Hello,
I accidentally plugged in an array of 230+v in the charging port of the Delta Pro. Within seconds it started smoking from the back. I immediately unplugged the cable. Everything still works fine except the solar charging.

EcoFlow won't honor the warranty because of human error. I asked about the auto over voltage shutoff and told them it didn't shutdown. They said that I went too far over the 150v limit and needs to be repaired. They're not much help and selling seems to be their only interest. I want to know if I can fix it myself or reset it somehow.
I can't seem to find any repair shops in the area.

Any help would be appreciated. Thanks in advance for your help, Wes

Can you give a link or such about this “auto over voltage shut off”?

In most cases (not sure about Ecoflow), you simply cannot, at all, not even a little bit, go over the solar voltage input limit. If you do, you “let out the magic smoke”. Which sadly sounds like what happened here. Perhaps it can be repaired?

It probably needs a pcb if they even sell such things. Likely any onboard SCC processors and probably even the traces have let the factory smoke out.
I think the overvoltage refers to battery charging, not headspace QC testing.

My neighbor did the same thing even with my multiple warnings advising him not to go over SCC voltage on his Delta Pro. There is no over voltage protection and no one would repair it. Anyway he had to buy another complete unit.
 
it looks like a very compact build, maybe they will interested in selling you the charger board - but you shall be able to check what is wrong...

I found a teardown video:
Vere neat product.

I wonder where I could buy the charger board. I'm sure Ecoflo, if they even would sell one, would be high. I'm gonna take it apart and see if there's some visible damage. Maybe something easy to fix. I know I'll have to drain the power from battery to keep from looking like a skeleton lol.
 
I would personally weigh my options.
If you are unfamiliar with electronics at all I wouldn't even bother opening your unit up at all.

As it stands, you have a good chance of reselling it to someone who could fix it or who would have a use case that doesn't need the PV input at all.

If you start delving into things that you're unsure of you could do more harm than good (on top of injuring yourself) and make it so that any recourse you could get from EcoFlow themselves or from anyone who may want to buy it used.


But if you are familiar with electronics, it's obviously worth trying to fix this multiple thousand dollar battery system if you think you're comfortable delving into it.
