[RE-wrenches] Enphase voltage out of range errors

[Alan Ross]

On one installation, I had the same error cod issue.  The project also used
the M190 inverters.  The issue ended up being a loose connection between one
of the inverter-to-inverter connections.  After re-checking all of the
connections, and making sure the connection was tight, the error code did
not come up again.

Subject: [RE-wrenches]  Enphase voltage out of range errors

Friends:

We have one site that is experiencing ongoing problems with errors
indicating, "AC Voltage Out Of Range."  This has occurred on two of 17 M190
inverters.  Apparently the voltage is not really out of range, the inverter
is erroneously reporting.

I have one replacement in hand and was just about to drive the 2 hours to
replace it when another inverter indicated the same problem.  I ordered a
second replacement.

I fear that soon after I return to my shop from the job I will see another
inverter with this problem.  Has anyone else experienced this error?

Thanks in advance,

William
