Nope. Just messaged them a few weeks ago and all they would do is say new firmware is in the works but couldn't give me any specifics. I'm coming up on one year waiting for this mysterious firmware update.

Inverter Shutting Down
- Thread starter lucassaugen
- Start date
I'm on an M4.
System 3.1.7
Power 1.5.8
Safety 1.5.1
My app shows I have the latest firmware but who know what that actually means. It did show I needed an update when I first had it installed and they did do an update a few months later.
I think the issue is with the safety firmware since the MCI is part of the Rapid Shutdown.
From what I've gathered solar roof uses different MCIs than the solar panels do and is likely why the problem doesn't exist for solar roofs. At least I haven't heard or anyone with a solar roof having this problem.
Hey all - been searching the interwebs for a solution myself, just had my 13kw system with two M8s commissioned. Same problem, one inverter will shutdown during production and reset itself. Also noticing that same inverter will not power up in the morning despite getting irradiance. I'll have to flip both DC disconnects to reset the inverters in order for this to operate. Put in a ticket with Tesla, will report back if they do anything.
Same issue here. M10 Delta, new Tesla installation. I updated software via the M Professional app to 3.1.8 (system), 1.5.8 (power) and 1.5.1 (safety). The inverter shuts down at the slightest shadow, stays there for 10-20 minutes.
The app shows error(1) arc fault, but given that it clearly happens due to shadow from clouds I don't believe it's an actual arc fault.
On full sunny days it's perfect. Anything less than full sun and it's a joke.

Do you have panels or solar roof? Just wondering. I think it's exclusively a panel problem but I don't have enough data yet.
Regardless, please call them and tell them to fix it ASAP. I've been dealing with this for over a year now. I can't believe a firmware fix is actually in the works. The only solutions I know is to replace the MCI with a standalone RSD device or replace the inverters with a different brand and swap out MCIs.

Still Trying to Figure This All Out
This was my Delta M4 with 3.1.2 FW back on May 2nd
And it was updated by Tesla 5/4 with 3.1.8
I still have a long way to go to get what is supposed to be a 5.25 kW system (split 2 kW SE and 5.25 kW NW) to get anywhere close to what it should put out.
I do have some shading that I need to deal with. Tree trimmers coming next week. At some point (statistics won't show when) it has produced a reasonable amount.

Sure that can be a can of worms. But there are circumstances (like this is the perfect time of the year) where it should be more than 30% of ideal at the maximum exposure time.
I am not sure when those maximums were recorded in the last 4 months but it was not in the last 30 days for sure.
30% more than ideal? What is ideal? I have never gotten close to the specs of my panels.

Wanna report back to this thread:
I had similar issue on my system (see previous post) but on top of that, my PW was not powering my house reliably during peak hours. When I logged in to my inverter I can see L1 over voltage or similar error before the inverter shutdown.
Tesla found something wrong with my incoming utility voltage and PGE found I had a faulty neutral.
Ever since they fixed it I haven't seen the inverter shutdown again. And my inverter FW is 3.1.7, it is older than what some of you have on your inverters..... So maybe a 3.1.8 problem? I wonder if it is possible to download older version FW to give it a try.
