I have 2 Apex 300s and the Hub A1.
When I connect either Apex300 directly to my transfer switch, the results are as expected - 120v and 59.9 Hz consistently (per Kill A Watt tool).
However when I connect either Apex 300, or both, through the Hub A1, the resulting power does not have a consistent frequency - it moves from around 58.5 Hz to 60.5 Hz, cycling every three seconds.
Further, this is observable in powered devices - fridge and microwave - have an audible surge sound matching the three second cycle shown via the meter.
I’m no expert, but this doesn’t seem right, and is concerning that it could damage powered devices over time.
Has anyone else experienced this with their Hub A1 or are folks getting the expected results of consistent frequency output?
Any recommendations on how to address this?
Thanks!
Hello,
Could you please provide the DSP version and SN? Additionally, could you check the frequency displayed next to the AC output icon in the app? We would like to compare it with the data measured by your electricity meter.
Thank you for your cooperation! If you have any other questions, please feel free to let us know.
Hello, Certainly.
DSP version: v2174.09
SN: HA12524000105682
Although I don’t see the frequency in the app next to the AC output icon, when I drill down into the AC output, I see it there. Watching the display for a couple minutes, the frequency fluctuated between 59.9 and 60.8 Hz (screen shots attached).
Thank you!
