Error E004 Apex 300

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."




Is it possible for your engineers to send me the correct firmware today?

Thank you.
