I’m seeing occasional nonsense data for the energy statistics for my Apex 300.
Here’s an example:
Notice how the grid shows 53kWh, with all of it happening across 6 hours (10:00, then 16:00-20:00).
These numbers are literally impossible, as my Apex300 is connected with a 120VAC power input. Grid input is set to 12A, so even if it were taking grid input at the maximum (12 x 120 = 1440W, roughly 1.5kW) this would only account for 1.5*6 = 9kWh. Even if it were running at maximum input for 24 hours, that would still only be under 36kWh. There’s simply no way you can get 53kWh out of a 1.5kW grid input in a day.
Most dates do not show this bug - here’s a more normal looking day with data that is believable:
If I zoom in on one hour, I see this:
Somehow the Apex300 is reporting that in one hour (19:00 to 19:59) it pulled nearly 15kWh from a 1.5kW input. Nonsense.
Now that I look more closely, I’m seeing other days with impossible values.
Here’s the 12th of may (yesterday):
Notice the spike at 0800 hours:
Again, there’s no way the Apex300 could physically pull 6kWh from a 1.5kW grid input in one hour.
As far as I can tell, the PV and AC data looks normal to me, it’s only on the Grid input where I’m seeing these anomalies.
Here is the Power Input data for that time period (Grid: blue, AC : orange)
The power data looks correct to me: I’m in self-consumption mode. i ran a tea kettle which ran on battery power. Afterwards the Apex300 used grid input to recharge. There is a spike in Grid input, but it’s about 1.5kW, and it lasts about 15 minutes, which adds up to about 1.5 / 4 = 0.375 kWh.
If I zoom in on the Grid portion only for that one hour period, I see this:
As a rough estimate, this is:
- baseload of 400 watts x 1 hour = 0.4 kWh
- two spikes, small one of 0.2kWh, big one of 0.4kWh.
- total should be about 1.0kWh
yet the Apex is reporting 6.0kWh!
It seems like the Grid calculation math is simply faulty?
I see there’s a reddit thread where someone claims:
I have reported the same on my EP13K install, I was told its a bug on the server backend and they are addressing it. That was about a month ago.

More info - I was having WiFI problems locally (which at first I thought was another Bluetti server outage, see Another Bluetti Server Outage? - #10 by JohnD333 )
To diagnose my WiFi problems I started running a Ping test against the Bluetti on the local network, and I feel like there may be a correlation between WiFi problems and the impossible energy statistics.
Could it be that when the Apex 300 is having trouble reaching the Bluetti servers, it retransmits data, and the server is double (or triple…) counting the numbers?
I’m going to improve my WiFi setup and see if that improves the statistics collection.
App main page shows apex with strong WiFi. 3 out of 5 bars. Network settings within App shows 2 bars. This is unchanged and has always been sufficient for 7 months with the Apex. have cameras and garage door IoT stuff further away and they work fine.
I have always used Time of Use for low cost electricity recharge. Range 35% to 85%. The reading of charge levels at various times of day during this outage were consistent with previous days, but I was concerned because I still had no in/out watts readings. So,… I changed setting to Backup. Sure enough, within a few hours it was 100% charged. Now the strange part - the advanced settings (System Switch Recovery, Grid Self-Adaptation, and 28 amp charge rate were showing as enabled where they were not yesterday. Before this issue they were all enabled. I did try yesterday but it looked like I was unsuccessful in setting the charge rate to 28 amps. Overnight it is showing 28 amps.
You may be correct about partial
Data pack losses this cloud does not get the full read when I make inquiry. So maybe settings were fine all along.
Still not showing in/out amps but charge status has remained at 100% since this morning which it will do if not on Time of Use.
