Passing this info along
One of our Enphase customers reported that his local electric utility
installed a new metering system, TWACs by Aclara. Once they installed a
new meter on the service, the system began registering ACFOOR (AC Frequency
Out Of Range) messages.He contacted Enphase and th
Dave,
In multiple conversations about this with both the utility and Enphase
there was concern about high inductive loads, possibly from the paper
mill in the town, that turned out not to be the case. The fix Enphase
developed worked, but I thought it would be worth mentioning.

Dave,
The problem occurs when the kWh meter sends data. I would expect any
neighbors' meters on the same transformer to cause trouble. And probably
neighbors that are not on the same transformer too.

I'd like to revisit a thread from early February where we were discussing
Enphase microinverters going off line due to utility power quality issues
when "Pinging" of smart meters occur.
I have a system where I was told by Enphase that they applied their software
fix in late March, but in this c

Dave,
We have been having the same problem with an Enphase system in Maine. I
have been dealing directly with the third tier engineers at Enphase and
they are working on a software fix for this. The"event" itself is only a
fraction of a second but IEEE requirements are that the inverter shut
down
Wrenchsters,
I have an Enphase 7.5kW system on a residence with utility Smart Metering,
both the PV Production Meter as well as the utility billing meter being
"read" every hour. This system has experienced many "AC Frequency Out Of
Range" events since the system was installed. Below is copied
