Hi! I’ve been getting some very strange readings from my Bluetti app.
I have an Apex 300, and when I check the Bluetti app, occasionally the grid power listed in the app seems to be wildly different from the actual power measured at the outlet that the Apex 300 is plugged into (I have an emporia Vue 3 monitor in my electrical box that is monitoring the line that the Apex is plugged into). I was wondering if this might be a bug in the app or an issue with the unit.
For example, (see screenshot) last night the Emporia showed that that outlet pulled .304 kWh from 6AM to 7AM, which looks to be correct. My window AC unit is plugged into my apex and pulls 300 watts when running, so this makes sense.
Here is my setup: I have the Apex set up in Self-consumption mode, and I run the AC from solar power during the day. By the time it gets past midnight, energy storage has dropped to 20%, and I have the Apex set to not drop below 20% in SOC mode, so it feeds the air conditioner with passthrough and holds the Apex at 20% with grid power. I also have the Apex set for Max grid input current 5A, so it usually pulls 600w from the outlet when charging.
However, my Bluetti App says grid power was at 2.7kWh last night between 6-7AM (see the huge blue spike in my screenshot). This should be impossible, as even if the Apex was charging at 100% for the entire hour, it should only pull .6kWh from the outlet, and this is 4x that number.
This discrepancy has happened a few times over the past few nights, where I have a weird 2kWh-4kWh grid spike happening overnight. I have never seen this before, and it seemed to have started one week ago. Does anyone have any idea as to what might be going on?
Thanks!
