incorrectly calculates the load in watts

Product Discussion BLUETTI Apex & AC Series
1

Hello, I have two Bluetti EB70 and Bluetti AC70P stations. When I connect a device to the EB70, the screen displays the power consumption in the range required by a particular device. When I connect the same device to the AC70P, the screen shows twice as much power. Using a light bulb as an example, the EB70 shows 45 watts, while the AC70P consumes 130 watts.
The current firmware versions are
IoT -v9046.04
ARM -v2152.05
DSP -v2112.06
The serial number of the AC70P station is AC70P2511001687699.

I strongly recommend using standalone power meter with Bluetti power stations (that plugs into wall socket).

  1. Reported power could be any of:
    a. Active power
    b. Full power (active+reactive)
    c. Power pulled from batteries (inverter losses included)
    There is no consistency here among Bluetti product line, and there is no reference in product manuals. Some load has a==b (like incandescent bulb), some has a<b (like LED bulb). My EB3A shows (b), when my AC200Max shows (a).

  2. There is no declared precision for power figures shown by power stations at all. Strictly speaking, it means there officially is no measurement device inside. Just showing some figures to help customers understand ‘small load-average load-big load’.

  3. Precision for measuring small loads (<10% of nominal load) is expected to be abysmal.

Can you provide the latest firmware versions for correct display?

Hi @BohdanK, we are deeply concerned about the issues you have encountered.
The AC70P as a new model, has its output display logic rules.
When the apparent power is around 50W, the LCD screen will display the apparent power.

We did consider displaying only active power uniformly. However, this would lead to certain issues—because the inverter needs to determine whether there is an overload, especially for inductive loads, which must be judged based on apparent power.

Please don’t worry about it, the different display will not affect its usage. Actually, it only consumes 45W to load your lamp.
Currently, we do not have a new firmware update available to modify the display logic of the AC70P.
Please feel free to contact us if you need more help.
