Percent % Displayed On Screen and App for AC200MAX

Product Discussion BLUETTI AC Series

Bluetti Technical, perhaps, provide a comments on calculations below.

  1. Is the Percent % displayed on the AC200MAX screen and app depicts the true Battery SOC% ?

If so, then this may be a proper way to use the data:

A) Measuring the standby Active, Real, True power load on the batteries, no external load, of the AC200MAX with DC & AC on, over 13 hrs, by the difference of Percents % from 0 hrs to 13 hrs:

AC200MAX + 1 Bat, On Standby, No Load
AC200MAX + 1 Bat = 4096 Wh - DC & AC On

  • After 13 hr, No Load, (95% - 85%) X 4096 Wh / 100 = 410 Wh
  • 410 Wh / 13 hrs = 31.5 Watts
    = Real or True or Active Power Draw from AC200MAX Batteries On Standby ??

B) Measuring the Total power Load by Connecting RV (on standby, no appliances running) as external power load on RV30 outlet; then calculating Active, Real, True power draw on batteries of the AC200MAX with RV (on standby), with DC & AC on, over 13 hrs, by the difference of Percents from 0 hrs to 13 hrs:

AC200MAX + 1 Bat, RV Connected To RV30 Outlet.
AC200MAX + 1 Bat = 4096 Wh - DC & AC On

  • 12 hr, With RV Load, ( 98% - 85% ) X 4096 Wh / 100 = 532 Wh
  • 532 Wh Adjusted to 13 hrs = 576 Wh = ( 13 hrs X 532 Wh / 12 hrs )
  • 576 Wh / 13 hrs = 44.3 Watts
    = Total Real or True or Active Power Draw from Batteries With RV Load ??

Hence the Real, True, Active Power Draw from Batteries by the RV on standby. Meaning no appliances running in the RV electricals.
= 44.3 Watts - 31.5 Watts = 12.8 Watts.

  1. Is this a reasonable way to process these information for Real, True, Active Power Draw from the AC200MAX batteries ??

Why is the post not displayed as it wasbposted with appropiate line spacings, taking out the line spacings makes the post not easy to read :tipping_hand_man:

@bluetti_iamrouelfmaccom
When calculating the discharge time of the machine, whether standby or loaded, it is necessary to take into account 90% DOD and 90% efficiency.
The machine will have a relatively large self-consumption of power when both AC and DC are turned on, so we recommend that users, when the machine is not loaded with equipment, turn off AC and DC.

Bluetti, thank you :pray:t2::pray:t2:.
.
Since the reply does not comment on the questions asked, then will assume that the percent % displayed on the screen or App is the True SOC% of the batteries :tipping_hand_man::tipping_hand_man:

From the results above, with DC & AC On, it looks like the AC200MAX has a self-consumption of ~ 35 Watts, … just waiting for a Power load :tipping_hand_man:
