Around Sep 1 the Statistics for AC500 start show production summary for a day less than the actually produced and also it contradicts other calculations in the app.
9:57am PV Generation show 535.30kWh
4:09pm PV Generation show 541.80kWh
So, generated 6.5kWh.
Also on “Daily power profile” screen you can see 12:15-15:00 was producing over 1kWh.
Problem: On the “EnergyStatistics” per Day only 3.79kWh ( should be 6.5) and max production around 0.75kWh ( should be over 1kWh) which is incorrect, at that time I was watching on main screen it was ~1.3kWh entire hour.

4:09pm
Seems like that the usage of AC gets pulled off the production value. Add both together and you have your ~6 kwh. There was a bug recently with this monitoring. Did you update your firmware already?
Hi @artemb, Recently, our technical department has also identified this issue and is currently investigating and discussing it. We will address this problem in the upcoming version of the app.
Thanks to @Selfmadestrom for their assistance and explanation.
I think this issue started after I updated firmware a week ago (the prev update I did a couple years ago )
And I noticed that something related to AC value being subtracted from Production value on the Graph, but it’s not necessary the exact formula used by developers internally.
Hi @artemb, Thank you for getting back to us so quickly.
we have applied to upgrade your IOT Our IT department will push the latest version of firmware to your machine in 24 hours. Please upgrade it tomorrow.
Please do not load any device when upgrading it.
Meanwhile, we wonder about your Bluetti app’s version, can you update the Bluetti app too?
Please let us know if it works.
Hi @BLUETTI_CARE,
Is it possible to tell dev team that “Energy Statistics” shows as PV the Wh which went directly to battery?
It excludes the electricity used directly to power AC inverter at the moment of production form solar.
It would be super cool if the code on “Energy Statistics” would be something like:
“total solar production” = “electricity went to battery” + " electricity went to AC load"
I believe that what I’m saying is realistic to do as the “PV Generation” value looks accurate, so somehow it gets correct calculations.
Also all was working fine before I updated IOT.
Hi @artemb, I have conveyed your feedback to the development team. Currently, we only track total power generation, not the power and energy charged to the battery. I’m afraid your request may be difficult to implement.
It seems the issue wasn’t resolved after the IOT upgrade? If you’d like, we can also roll back the previous firmware for you.
