AC500+B300S: 004 Battery Voltage High - Hardware

Dear Community Members,
I have an AC500 with one B300S used in Standard UPS mode which is not granting energy to connected devices once energy from grid shut down. An error message occurs: 004 Battery Voltage High - Hardware.
The only input is from AC grid (231V / 118W) while AC output (as for now) is 230V/114W.
Current Firmware is the following:
IoT: v9041.02
ARM: v4048.02
DSP: v4047.03

Could you please provide me with any suggestion aimed to get this fixed ?
Many thanks and best regards.

This needs to be solved by updating the firmware. What is the SN code of your AC500 please ? And which country are you using it in?

Hello,
please, find below the requested info:

SN: 2241000193290

Many thanks !

Hi @mrusso70 , Thanks for providing the SN code. You are expected to receive a push notification of the firmware update within 24 hours.
Please keep an eye on the app and keep it updated at that time, thank you!

I appear to have the same issue…error codes 004 and 103. SN: 2238001475962, US version (110V)

@BLUETTI I have a similar issue, would the firmware update correct it?

Whenever I try to charge to 100% I get the 004 error on my Bluetti AC500 UK Version (240V). If I let it sit for a while until the alarm goes away then I can top up the few % it’s lost to 100%, but it happens every time I try to do a big charge after using it.

The B300s firmware is: v1002.08
My SN: 2232000014089

@Carnivalius Thanks for providing the SN code. You are expected to receive a push notification of the firmware update within 12 hours.
Please keep an eye on the app and keep it updated at that time, thank you!

@Daniele Engineers have done a bulk push of the firmware for AC500. Can you please upgrade to the latest version and see if this still happens?

Hi,

Is there a reason why BLUETTI does not push the FW to everyone?

Thanks,

@tl0114 Engineers have indeed pushed a bulk firmware update to the AC500.

Hi Bluetti,
