Hello Wrenches, Anyone experiencing issues with comm card failures on SolarEdge inverters? We have some systems installed in 2012 exhibiting similar behaviors. The systems are producing data, it is registering on the inverter, and our independent utilty meter, but is not reported to the SolarEdge portal. Next day(s) it reports production to the portal but the missing data is never filled in. I have attached a small graph from the portal dashboard.
Typically if a network connection goes down, and then is restored the data should be uploaded after the connection is back on line. In this case their remains a hole in the data, for that day, indicating that data was never uploaded. We had one system which exhibited this "missing data" symptom on accasion over a 2 month period of time. This was diagnosed, as a failing comm card. Once that was replaced we have not seen the issue recur for that site. But now we are seeing similar behavior from three other sites, all installed a in the second half of 2012. Just wondering if anyone else has encountered this.
