[RE-wrenches] SolarEdge comm card failures

2016-04-18 Thread Carl Adams 
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.

Thanks
Carl Adams

Carl,

We experienced a rash of Comm Card issues with several SE installs over
several years, but none exactly as you describe.  Our issues were almost
all resolved with a board replacement, but a few were particularly vexing
with many return service calls to get a resolution.  We seemed to have the
most problems with the single phase 10k inverters.  In general, SE tech
support was helpful, although a bit paint-by-numbers at times, as well as
very slow to answer for much of 2015.  As best I can tell, the issues have
begun to settle down most recently.

[RE-wrenches] Delta Solivia

2016-04-18 Thread Drake 

Hello Wrenches,

Does anyone have experience with Delta Solivia inverters? Are they 
good and reliable? Do they have any drawbacks, like having a high 
noise level, nuisance shut downs, failures, etc?


Thanks,

Drake
