I don't think you are imagining it, I think Enphase really is doing it in some cases, based on what they told me on the phone. But it's up to their "escalation team" to decide.
Edit: I subscribed to the thread and got a message about someone who got his D380s replaced with M215. The post was deleted from the Enphase board today, probably by Enphase. They probably don't want to offer this option to everybody. I won't be too upset if they don't for me, as long as they make good on providing replacements and paying for labor.
You'd have to lose either 4 M190s or 3 M215s.
I wonder if Enphase can software limit the maximum power with a firmware update so that the M215s are limited to the same maximum power as the M190 - 0.8A nominal instead of 0.9A nominal)?
No idea. Maybe they can. But it probably still wouldn't pass inspection.
Do all of your panels point in the same direction? I have heard of people succesfully arguing for a lower limit circuit breaker so they could install more panels/inverters since not all of them would be hitting peak power at the same time so there would be no issue of nuisance trips - but it looks like all your panels are facing the same direction right now.
Not exactly the same direction, the ones on the D380 are at an angled, while the ones on the M190s are more flat. But they still tend to peak around the same time.
madbrain said:Heat could be an issue - but I doubt it's the real reason your D380s have failed. There really seems to be some sort of issue with the D380s - just by reading the Enphase community board, the D380s seem to have the highest rate of failures. M190s seem to be generally good unless you happened to get yours out of a bad batch where they can also have high failures rates. The M215s seem to be very good with only very rare failures.
OK, that's good to know that it's probably not my install. The temperature doesn't look excessive when I have monitored it on the D380s, even at the time of the intermittent 0W events.
The M215s are fairly new, perhaps too new to be able to accurately assess the failure rate.
