I have the D40 unit and when using it I cannot see any output wattage being displayed on my AC200L screen. This occurs with small loads all the way to 20 amps. I can see the time remaining calculation changing indicating that the AC200L recognizes the load but it will not display it. The app is the same way, no DC wattage output displayed when using the D40. I can see wattage when using the cig socket.
Does anyone else have a working D40 yet that can verify if they can see wattage used when the D40 is connected?

We did a test and it does not appear the situation mentioned above. Could you please provide me with the series number of the D40 (back or bottom of the unit)? Additionally, could you please take a short video about the issue?

@BLUETTI_CARE The serial number is 1030089C30 and 5241000079.
I am unable to attach a video file to this message. I was however able to respond to the e-mail sent and attach a video I made today. Please see the e-mail reply for the video. I used the D40 again today with the same results as before. Basically no DC output is displayed until I press the DC button to turn off the DC. The output displayed “0” and went to “192” for about one second (192 watts) and then went blank as it should. The hours remaining calculation changes with load and the AC200L is definitely recognizing the load but not displaying it. The app does not show the load as well

@BLUETTI_CARE I just took a new video and photo. Neither could be uploaded because it said file format extensions were not supported as shown in the above message. I replied to the email sent and was able to attach the video to the reply
@Scott-Benson May I have the ticket number of the email? I can’t find the video and photo mentioned above. I am sorry that I need the SN of the AC200L as well. Thank you.
There was no ticket number. Just your response to this post. I replied to that email again and sent the video again. 2335910048404 is the serial number of the ac200L. Give me another way to send a video and ai will try that
@BLUETTI_CARE here is @Scott-Benson video showing the ac200L not displaying the D40 output.
@Scott-Benson I have reported it to the technical department and it is expected that a firmware will fix this issue. I will let you know if I have any updates.

@Scott-Benson Please update the firmware to ARM2099.08 to test.
I will upgrade the firmware when I get home tonight. The interesting thing to me is that I have seen no other reports of the DC load not being displayed. Strange how my AC200L will not display but others are fine. Is mine the only reported case or are there others?
I am unable to upgrade my firmware because no firmware update is showing to update. Maybe try again on your end
@Scott-Benson OK. We will check the problem.
Here is my serial number again and my current firmware versions
@Bluetti_Care Basic straightforward question… If I have my D40 connected to my AC200L and also have a PV200 solar panel connected to the same D40 (producing 10 amps output) what is the maximum expected output amps when in load mode. Is it capped at 20 amps or will adding the PV200 panel increase the 20 amp output limit while in load mode to 20 amps plus additional solar output?
@Scott-Benson The max output current is 30A.
Well…my D40 does not increase the output above 20 amps when connected to solar or allow any electrical flow through the PV input when in load mode. The manual states PV / car mode unavailable when in load mode. Are you certain 30 amps are available and if so it appears that I have a defective unit.
@Scott-Benson I’m sorry I gave wrong information. The D40 cannot reach the maximum output of 30A in load mode.
- The two input ports of D40, DC input (connected to the 48V RV port of AC200L) and PV input cannot input at the same time. The PV input takes precedence. It will switch to the DC input when there is no PV input;
- D40 can only use load mode when the input is DC input (connected to the 48V RV port of AC200L).
In non-load mode, when the input is PV or lead-acid battery, and the input energy is large enough, the output can reach 30A.
