Low grid voltage error (E114) on AC70P

Product Discussion BLUETTI Apex & AC Series
1

Hi,
I’m from Ukraine and I use an AC70P. I get the E114 error whenever the voltage drops. Could you provide a custom firmware with slightly adjusted thresholds so the unit can handle these situations better?

S/N: AC70P2441002722490
IOT: v9046.04
ARM: v2152.05
DSP: v2112.06

Thank you in advance

Hello, please follow these steps to troubleshoot the issue:

  1. Check if the firmware version in the app is the latest.
  2. Enable the grid adaptive mode in the “Advanced Settings” of the app.
  3. Set the charging mode to silent mode.

If you are using a wall charger and have confirmed steps 1-3 but still encounter issues, please provide your SN code and DSP firmware information so we can push the firmware to you.

If you are using another inverter (like EcoFlow) or a generator to charge the AC70, please check if the wall charger can charge normally. If it does, the issue may be with the inverter or generator output voltage or frequency being unstable and exceeding our machine’s input range. In this case, please provide your SN code and firmware information as well. You can find the SN in the app’s settings page and the firmware information in the “Firmware Upgrade” page.

If after trying the above steps you still cannot charge via AC:

  1. Long press the ACON and DCON buttons to enter the settings interface, then long press the DC ON button until you reach the VE interface. Check if the current calibration voltage corresponds to your region (e.g., 120V corresponds to the USA). If not, please contact our technical team.
  2. In the app, click on the AC input icon, enter the AC input interface, record a video, and then contact our technical team.

Thank you for your cooperation!

Hello @BLUETTI,

I am located in Ukraine, where, due to the war and constant shelling of power plants, we are experiencing voltage drops and instability in the electrical grid.

I’ve already reviewed the documentation and tried using Silent Mode with Grid Adaptive Mode enabled, but unfortunately, this did not help. The device is connected directly to the grid, and I am not using any inverter (such as EcoFlow) or a generator to charge it.

Currently, the device is running DSP firmware v2112.06.
Model: AC70P
Serial number: AC70P2441002722490

Could you please push the firmware?
Thank you in advance.

OK, I have registered the firmware upgrade for you.
