About my Solar CT that is dropping off, it looks like I have another issue going on. I’m having issues with groups of microinverters randomly dropping out with an “AC_OVER_FREQUENCY” error during times when the sun is high in the sky. On the Sense Power Meter, it looks exactly the same as when a Solar CT drops out, or shows a lower than expected reading. The microinverter vendor is shipping me an AC power analyzer that will monitor and record cycle-by-cycle metrics to hopefully get to the bottom of what’s going on. So on my end I’ll get that knocked out first. There definitely was an issue with one of my Solar CTs, but re-seating the connector and double checking it was closed all the way may have taken care of the issue. Won’t know for sure until I get this other issue resolved.
On a side note, I bet the sense would make a kick ass AC analyzer with the right software. The sampling rate is certainly high enough. Adding a voltage “Power Meter” and a frequency “Power Meter” would be pretty straight forward I would think. Having a real-time “oscilloscope” of the AC waveform would be pretty cool too, especially if it had the ability to hold, store and zoom. Perhaps that would be an add-on software option down the road? I know this isn’t really the focus of the Sense device, but I would think the hardware is fully capable.
