. First off, the Enphase AC Battery state-of-charge (SoC) with 5-minute sampling, then Normalize/Resample (.wav
):
Playback requires an Internet connection.
Battery charging with 15-minute sampling, then N/R (.wav
):
Playback requires an Internet connection.
Battery discharging with 15-minute sampling, then N/R (.wav
):
Playback requires an Internet connection.
Battery charging (left channel) and discharging (right channel) with 15-minute sampling, then N/R (.flac
made in Audacity):
Playback requires an Internet connection.
PV generation as recorded by the Enphase with 15-minute sampling, then N/R (.wav
):
Playback requires an Internet connection.
Bonus bonus, thinking ahead, maybe straying into "sonification"...
PV generation from same source, then: Normalize, Low-Pass Filter at 500Hz with 24dB/octave roll-off (to suppress anything above 'daily' and make seasonal stand out), Normalize, Resample:
Playback requires an Internet connection.
I locally record some Enphase AC Battery stats every 5 minutes, including state-of-charge (SoC), ie how full the battery is. I currently have data from 2018-08 to 2019-09 inclusive. (The unit was not installed until a few days into 2018-08.)
cat data/16WWHiRes/Enphase/201*.log.gz | gzip -d | sh script/mkaudio/EnphaseSoCtoWAV.sh > ~/tmp/out.wav
Flows in and out of the battery (charging and discharging) are also recorded and available remotely from Enphase at 15-minute resolution. I tweaked the script to select which parameter to audify, eg charge or discharge. Data from the same 2018-08/2019-09 range is used as above.
