We’ll yes, but then there are other trade-offs. The installers we spoke to, the vast majority including Tesla recommended SolarEdge with optimizers for our east-west facing roof with some early morning and late afternoon shading at lower roof elevations, including installers than offered other equipment like microinverters. Only one recommend Enphase with microinverters, and they only did Enphase installs.If they only did micro inverters instead then we wouldn't have to worry about the entire system ever going down.

If I really wanted to put redundancy into the system I could have split the panels into two independent systems with two inverters. But then might not be using the inverters efficiently enough…
Been debated on these forums and the rest of the internet as much as anything else. Search and you get plenty of threads like these.The only trade-off I'm aware of is cost. You said there were trade-offs but you didn't list any.
I have big inverters on small strings. No big dealWe’ll yes, but then there are other trade-offs.

I guarantee you I did more research on the topic than 99.99% of consumers who get solar.Been debated on these forums and the rest of the internet as much as anything else. Search and you get plenty of threads like these.

I wouldnt doubt that at all, which would virtually guarantee that the solution is the right one, for you.

All things being equal, most installers will recommend the easier to service option which is not necessarily in the best interest of customers. My impressions is that many installers don't like microinverters because they have get on the roof and remove panels for replacement which they don't have to to do for string inverters even though a string inverter failure is a much bigger pain/impact for the customers compared to one or several microinverter failures.
I agree.Also, now that Tesla is only offering their inverter and it does not include optimizers or panel level monitoring, I would not be a Tesla customer if I were ordering today. Optimizers was the compromise I was willing to make over not having micro inverters.
Update
Tesla came out today on schedule and replaced the inverter. The tech that came out had to go through all of Tesla’s troubleshooting of the failed inverter first though, even though we had the replacement on hand. Part of their process I guess. Nothing tried including flashing to the latest SolarEdge firmware was able to get the inverter to do its thing.
New inverter is up an running. Everything looks good in the Tesla app. Even though it was only 15 days without production, it seems a lot longer. It did cost about $175 per week of downtime I calculated from cost of grid electricity purchased and lost incentives and credits.
I do need to setup the SolarEdge app again though it seems. I asked about its Zigbee connection the inverter uses connecting through the little black box Tesla gave us at install. The tech said he would swap the card from the old inverter to the new inverter then change the serial in his online admin interface. But it still looks like my SolarEdge app is looking for the old inverter even though the black Tesla box seems happy and not connection error lights.
One has to get the new inverter Serial number updated in the layout to work. He/she should do thisUpdate

I didn’t have a panel layout before. But it looks like I’m going to have to call SolarEdge to update my account with the new inverter. I don’t see anyway to do it myself.Did it retain your panel layout?
If tesla will do not, are you the installer of the layout?I didn’t have a panel layout before. But it looks like I’m going to have to call SolarEdge to update my account with the new inverter. I don’t see anyway to do it myself.
Maybe he didn't understand your point, but I did I have an SE inverter that has worked perfectly for 5 years, yet recently had an optimizer fail. I called SE support and after looking at my system to verify that was the issue, they sent out a new one over night FedEx and I had it installed and working the next day. Great support and that is the first place I call in the future.My only reason to post is rather than having folks guess, just going to support was the fastest way I got my issue resolved with my SE inverter started to fail once in a while. And this was sharing my experience with you
