I have a newly installed system that is having problems getting online consistently. The installer's electrical crew will be coming back this Friday to check on things, but I'm curious to understand what we are seeing and might be the problem.
The past three days (the only three days its been energized), energy production would start and seem to have the expected output for 2-3 hours. Then suddenly the system would be offline. I'd leave it alone for the day while the installer and SolarEdge remotely try things out (I'm being told the firmware is being updated). However, the next day it doesn't start producing until I use SetApp to redrive the pairing process. All optimizers are found and production hums along for 2-3 more hours and then goes day. The same pattern occurred the third day.
Each time, when I check the status via SetApp, it says only 2 of 28 optimizers are communicating. I don't know why 26 of them stop communicating each day.
Additionally, I'm being told SolarEdge is having some system issues right now, but we wonder if something is wrong with the consumption meter setup. I only get consumption numbers while the system is generating. When there is no production, I have zero consumption. The consumption that it does record is far higher than my average and my POCO's next day report of hourly usage does not show anywhere near that much usage. On top of that, even at 3 am, it shows "export" of 2-7 kW. From monitoring that, it feels like it is recording input as export, as the numbers (with some delay) seem to rise and fall noticeably as my 240v appliances cycle. From reading on the forum, this may be the result of one or both of the CTs being put on backwards?
Installation Details:
1 x SE11400H-US000BNI4 ("built-in" RGM and consumption meter)
28 x Solaria PowerXT-360-PD panels
28 x P370 power optimizers
Line-side tap (even though my panel could support backfeed)
Connected via Zigbee
Firmware:
CPU = 4.10.25
DSP1 = 1.0.1036
DSP2 = 2.0.910
Meter = 0.72.0
WSA = 1.6.9
