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:
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).
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%.
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.
Hi @snmya, Regarding this issue, please provide a screenshot of your UPS settings interface, along with the SN code and current firmware version of the AC200PL. We will then investigate the matter.
Thanks to @Mandp for your attention and reminder.

Please also have a look into different description of same issue:
Here’s my screenshots. Right now, station is draining from the grid about 25-45W (depending on the AC load), measured by both wattmeter and the measurement device from the electric company. And this drain is constant, just fluctuates in 20-90W range.
Hi @snmya, Thank you for providing the screenshot. Based on the information shown, the UPS is functioning normally.
The 20W or so output you detected is due to the cable being connected to the AC200L — a small voltage causes this standby power loss, which is expected. Although no active charging is occurring, the grid remains in standby mode, ready to supply current and voltage at any time, which leads to a slight power draw.
If you’d like to avoid this minor power loss, you can simply unplug the cable.
@BLUETTI_CARE Well, it’s not 20W, it’s often upto 50W, which is 36kWh per month, not so negligible. Unplugin the cable is, of course, not a real solution
It should be done dayly and at times everyone sleeps. But let’s say smart plug can be used.
When grid it is off by timer on smart plug and station is discharged to SOC Low, it will not switch to use Grid, will drain to 0 and everything will die.
It can be turned on/off by timer, but it cannot be turned off when the station is charged (to 100% or SOC High). So the rest of the night it will remain plugged and still drain from grid.
If I plug more consumers than station’s power, with grid connected it will just passthrough from the grid, but when grid is disabled by the plug station will shut down.
It would be great if this drain could be disabled by the station. Couldn’t it be, with firmware update? Or is it hardwired in the station electrics and it is impossible to implement programmatically?
Hi @snmya, Thank you for providing the detailed information.
A power consumption of 50W is indeed quite high and not normal. We’ve submitted this to the testing department for reproduction.
We’ll contact you once we receive a response.
