SE replaced this inverter as well. Probably a bad manufacturing batch, as these were the first 6Ks off the line.
I did kinda think Butch's "installer" comment was a jab, but it's sometimes hard to read intention through text. I have 100% confidence in my install, all equipment was treated like the expensive newborn babies they were (ever seen 40 newborns get pulled up a ladder one at a time with a rope? maybe this is a bad analogy), and I checked and double-checked everything. I even purchased $400 worth of MC4 to H4 adapter/jumpers to connect my H4 panels to the MC4 P400s. Probably wasn't necessary, but I didn't want to risk the inspector claiming H4 to MC4 is not a UL-listed mating, and definitely didn't want to risk connector failure and a meltdown/fire.
As for these LCD-free inverters, I would really really prefer a screen! I physically check my inverters several times a week for odd sounds, error codes, temperature (hand on fins, not whats on the display, temp probes can fail and read whatever), and just general output and operation/responsiveness to buttons. I feel like a local LCD on a device is much less likely to "lie" or otherwise display incorrect/old data than a networked connection, particularly if its going out to a cloud service first. I thought I saw where they were replacing the LCD with OLED displays, which won't have cold issues since it's basically an array of LEDs anyway.
