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
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
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.

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.

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 the
