Hi , Could you please help to fix error A049 BUS overvoltage?
It appeared recently after Low Grid Voltage erros during the week in Ukraine , when sometimes voltage was about 185-190V.
The issue is with this error A049 it stops charging after 5 seconds now.
I upgraded my EB3A to new firmware that appeared a couple of days ago. maybe this is a reason ?
could you help me either with new firmware or some reset function i can apply
Thank you for your patience. Here are some troubleshooting steps we recommend:
- Please disconnect all loads and then restart the device.
- Check if the device’s output is connected to the distribution box. If so, ensure that a transfer switch is in place to separate the device’s AC output from the grid. If there is no transfer switch, the device may report an error.
- If the device still shows related short circuit errors after restarting in an unloaded state, it may need to be sent for repair.
We hope this information helps. If you have any further questions, please feel free to contact us.
