When taking advantage of time-based feed-in tariffs, the formula consumption + battery power could result in a negative consumption number. I have no data between 6pm-7:15pm because I was exporting more than I was using.
I am trying to upload data that gives an accurate export/import, so I am pre-adjusting consumption by battery power before uploading. Of course, this can now result in negative consumption, which causes the upload to fail.
Do you have any suggestions?
Thanks.

v4 = v4 - b1 ?
v4 = -5040 - (-5640)
v4 = 600
It would be best to handle this with a flag in the addstatus request e.g. &bc=1 so it wonāt affect existing requests where this isnāt applicable.
hi, we just got shiny new PV system with battery (goodwe) installed last week and I would like to continue using PVoutput, which served me well for over a decade, to track production and savings.
Great to see that battery monitoring is available now, can anyone confirm if pvoutput can can calculate savings from battery system yet? (I know it can do this well for solar PV).
Iām currently exploring how to do this with Home Assistant but since Iām new to HA, the progress is quite slow
Not currently, but it would be a feature added in the future.
Installed 3 Enphase batteries, and now the PVOutput data doesnāt reflect imported power. Is there a way to correct this?
PVOutput would need to retrieve the battery data from Enphase, this would be separate enhancement in the future.
Aha. Any guesses when that might be? The system as it stands now isnāt useful to me and my ilk. I was really enjoying the daily cost calculation data.
Unfortunately a timeline canāt be provided at the moment.
Enphase is a little complicated given the battery data requires additional requests to Enphase and we are constriant by a total number of monthly requests, for all systems, which is quickly approaching its limits as more Enphase systems are added.
For testing purposes, do you allow PVOutput to make requests on your Enphase account? This is to sample the data and the number of requests will be kept to a minimum (1-2 per day)
I have a google sheet setup to pull my Powerwall data and upload to PVOutputā¦
Only just came across this thread but been hanging out for some battery support for a long time. So this is awesome news!
Currently my v2 includes battery output, and v4 includes battery input. Iām sure there was a reason I included outputā¦ but canāt remember anymore.
Anyway I just started logging the battery data into b1-6, and wonāt alter my generation or consumption data yetā¦ as I assume it will be manipulable later with settings. I guess Iād want v2 = v2 + b1, and v4 = v4 + b1ā¦ to remove battery outputs from generation and battery inputs from house consumption.
Iāve been logging my battery data since Feb 2023 in v11+v12. Is there a good way to copy that data to b1+b2ā¦ and once its all settled down, recalculate.
Thanks.
Been thinking about it overnight.
Power Used: I have been counting battery input and outputs in this figure from my server side. I shouldnāt have been counting inputs. Itās not used power, its stored power. I should still be counting outputs howeverā¦ so realistically Iāve been double counting any battery power in my power used.
Power Generation: I have been counting battery outputs in this figure. However I think I did this because if I didnāt, then PVO would count the power used as imported, and I figured it was better to have incorrect generation stats than imported stats.
I guess I need to know what the implementation will be going forward, to determine what figures I will be sending into PVO with my battery stats.
If a feature could be added to manipulate large amounts of data (knowing that I could mess all my data up and it canāt be reversed etc) and queues / rate limits can be added to stop your servers getting smashed
copy my extended data to battery data
b1 = v11
b2 = v12
remove battery input from power used
if(v11 > 0) v4 = v4 - v11
remove battery output from power generation
if(v11 < 0) v2 = v2 + v11
Iām not sure how the battery stats will eventually (or currently) effect net production calculations, so Iāll wait and see for now. My Generated is currently over reporting by the battery output, consumption over reporting by the battery inputā¦ but import and export are correct. Going back 3 or 4 years and fixing data would be greatā¦ but having accurate data going forward if probably more useful. I hope that made sense.
The Extended data rules should able to handle these calculations. It not possible to recalculate old data without reuploading which is limited ot the last 90 days.
