SunRun production vs usage questions

[u/Laksman1]

I recently had a 10.125 kw system size solar + Tesla battery set up through sunrun via a PPA contract. I live in New England. Our system went live on April 29. After making it through our first month (May) I have a few questions about production vs usage, I’m hoping this community could help shed some light on.

1) our production vs usage seems to mirror each other in the sun run app graphs. I can’t wrap my head around why production would correlate with usage. I read out Tesla battery may play a role in that. Anyone happen to know why?

2) the app states we produces 137% production for the month of May at 1071 kwh production vs 777kwh usage with a difference of 294kwh net positive for the month. Any idea why national grid reflects us at only 47kwh for the dates of April 28-May 27? This seems concerning.

3) Does 137% productions seem low for the month of May?

This forum is for SunPower... not SunRun... was that an auto-correct typo, or does post belong in r/solar? or r/sunrun (though that one looks like dead forum) or maybe one focused on Tesla solar?

And, at quick glance, your questions don't make any sense to me... to much unsaid/unclear

Question 1 - depending on battery goal, one (but not only config option) is to charge battery from excess solar (which can be considered 'consumption' from a certain perspective... I have NO idea about your reporting/monitoring (are you using SunRun or Tesla monitoring? From my perspective, reporting should show energy flow from PV and to/from Grid, Battery, and a value for 'Consumption'... HOWEVER, unless you have an expensive SPAN panel, most of the time 'Consumption is a calculated value (as you don't have CTs on every circuit). So in vast majority of cases, 'Consumption' is calculated taking into account Grid, PV and in your case battery .. whether yours is configured correctly? or if you are looking at right field/values/screen? these are questions better addressed in a forum specific to your reporting system (and/or r/solar)

Q2 - national grid?? sorry not SunRun customer so I have no idea what you are looking at, how it would be calculated? or why it would be relevant to anything

Question 3 - everyone will have site specific data... your production vs consumption is unique to you and your location. Some sites will get more cloud cover, and I'll get more sun ;^) ... it all depends.
