In a nutshell
7.7kWh used to charge the APEX300 + B300K, resulted in 5.1kWh useable.
1 APEX300 + 1 B300K using 2.4kWh each day idling in standby mode is not the way forward.
So I have 2x Apex300 and a Hub A1, now I don’t have the hub A1 plugged in to anything but I did not when I did it appears to run the fans at a higher speed for no reason, I believe this likely to be your power drain, as to why this happens I am not sure currently I use my setup to run my window unit in my sunroom and for emergency backup when needed, it’s also always on eco so after an hr of no draw from the AC it shuts them off, I don’t even use 1% from sundown when solar is gone until the morning when the sun comes up so 10-12hrs. Again like I said I would check if you have the A1 plugged into the grid check and see if the fans are running, not sure of your use case as you mentioned just receiving it and charging and and discharging for testing. Maybe someone from bluetti can chime in and answer why the fans constantly run with no draw while the Hub A1 is plugged in and not being used?
