Heavy Grid usage when not charging

AC200PL (+2xB300).

Hello. I am seeing something very strange and illogical. I have Time Control UPS mode and I am now in Peak time. Current charge is 95%, while SOC Low=30, SOC High=90.
I am currently using about 300W, and station shows it correctly. It also shows that it is not charging, which is correct and in line with settings.
However, it draws from grid 250W constantly! My understanding, this is for internal usage of the station, but then:

  1. It is too high, It draws from grid 250W and discharges to my devices nearly the same 300W making consumption 550W (because the battery is discharged and later it will need to charge for spend amount).
  2. It should NOT drain from grid in Peak mode, it should use internal battery (unless SOC drops to SOC Low value). The whole idea of this mode to save on energy bills when it costs more (during the day). This is absolutely incorrect behavior and should be fixed, or, at least, a settings switch should be provided (although I cannot imagine someone wanting it to work as it is now, it contradicts the logic of Time Control UPS).

Thank you.

P.S. I need to recheck the exact grid drainage value for several days, as immediate values from wattmeter and TOMZN relay are very different, someone is lying, so I will check by the meter from the electric company. But is is >0 in any case, and this is the problem.
P.P.S. Seems not to be that terrible, about 50-90W, not 250. But still, not ideal.

I am still not sure of the details of this function. That said, If you have set a minimum SOC and a maximum charge ceiling and you have a load on the power station, then the grid will pass through power to your load in UPS mode.
What it does do is stop your power station from charging to 100% and discharging to 0%.

I’ll stand corrected if I am wrong, lol. :grin:

It is “not charging” in theory, in practice it drains power from the grid. It is not related to load, load can be 0. It still drains power from the grid. In Peak time. When electricity costs more. Making this mode nearly useless. And it can perfectly NOT do that, because everything works if I remove the station’s plug from the outlet.

In that case tag Bluetti Admin, they may help…
