Error E004 Apex 300

Product Discussion BLUETTI Apex & AC Series

Hello,
Today I purchased a new inverter with an additional 300K battery.
I connected everything and started charging it.
When the system reached 97% charge, I decided to install the firmware updates.
After the update completed, the charging stopped and I received Error 004.
Please help me understand what this error means and how to fix it.

Thank you!

I have error E004 Inverter Output Failure (Inverter Soft StartUp) - can you send me new update? As I see on forum it helps.

Hello,

Error E004 indicates an inverter output fault. Please follow the steps below to troubleshoot the issue:

  1. Upgrade all firmware to the latest version in the app.
  2. Disconnect all loads and then restart the machine.
  3. If the machine still reports a related short circuit error when unloaded after a restart, it will need to be sent for repair."

I apologize for misunderstanding…

Could you please register my SN code and firmware version information and arrange for a firmware update for me?

I’m in Ukraine now… Sitting now without light…

Looking forward to your response!

Hi!
I bought this model just yesterday. I simply started charging it because the battery was only at 25%. I didn’t connect anything to it at all, so there was nothing to disconnect.

When the charge reached 97%, I decided to update the firmware.
After all the updates finished, this error appeared.

  1. Could it be because I performed the update while it was charging from the wall outlet?
  2. I also read on the forum that you can send a firmware update specifically for my unit, and that it might fix the issue.

Could you please advise what I should do now?
Is it possible for your engineers to send me the correct firmware today?

Thank you.

Hello, P050A and P090D are the same type of cable, typically used to connect battery packs.
