If it has a fan, I’ll be getting my $ back on all four of the ones I have, 2 V1 and 2 V2. I believe if there were a fan it would be evident in the pictures he has sent.
This looked like a fan to me but I've never heard a fan running is why I was asking

The coils in the heat sink are on the AC side for filtering. The DC coil for energy storage is on the main board.
There is a small fan inside, but i've never heard it running, and it is basically worthless being inside a small enclosed volume, even if it were blowing in the right direction.
Wow. Who knew? Thanks for confirming

Can you identify in one of your pictures where fan is at? Unless what @1201 identified is a fan
1201 has correctly identified it.

I ve never heard that fan come on. I have to use an external fan to cool mine down
I have a neighbor with the same inverter and he has no external fans and hasn't had a problem. OTOH, he only has about 8000 watts of panels.
I added an external fan as a precaution and one would think there would be many complaints here if overheating or failure was an issue. I can't argue with their claim that the inverter is naturally cooled as the internal fan does basically nothing, if it is even programmed to come on.

With it buried inside, I’m not sure it would be possible for it to hear it.
Probably so. If I still had it apart, I would test it to see how loud it is.

Any chance you have a picture good enough to see a nameplate or label with a number on it or something?
Maybe this will help. Top right. I'm not home so can't zoom in enough on my phone.

Looks to be a NMB 06025SA-12R-AU fan. 12V DC fan, looks to pull on average .67A, at a max airflow of 45.6CFM, at 52db

I’m not sure you could hear 52db through the cover and with the other stuff close that would tend to attenuate the sound, like he said, too bad he already put it back together…….

I agree, something like that buried inside of the unit, you're unlikely to hear.
Regardless of whether it comes on and can be heard, I find it hard to believe that it does anything but recirculate hot air. Don't forget, the heat sink is on the other side of the main board. If anything it might initially help cool the SPS, but eventually everything will reach equilibrium and the net cooling effect will be nil.
I had a "dark start" this morning with my MIN (v2)/RESU 10hp because I accidentally had the battery disconnected before a grid outage. I tried a 9V battery on battery com enable+/enable- but it didn't seem to do anything. So instead I removed my car battery and jumped the TIGO transmitter (it wasn't completely dark). It works but wouldn't if it were truly dark, and it's annoying to remove my car battery and even open the inverter enclosure...
@MajicDiver Which two prongs are those? Do you have a V3 or V2? I would love to install a switch and connect it.

All of mine are v2,
Thank you. This little two-pin connector labeled CN6 circled in red, right? Looks like a XHB 2.54mm connector?

I know nothing about connectors, but that’s it. When you get something connected to it, post what you did please!
