The 'high voltage' warning or alarm is not unusual on new batteries that are not yet balanced. While less common, It can also occur on systems that have been installed and previously working reliably as well. | The 'high cell voltage' warning or alarm is not unusual on new batteries that are not yet balanced.

It is easiest to confirm this diagnosis in VRM in the Advanced Widget for the Battery Monitor as it logs this data over time. | It is easiest to confirm this diagnosis in VRM in the Advanced Widget for the Battery Monitor as it logs this data over time. |
To help the batteries balance quickly, keep the batteries fully charged and the system voltage stable until the errors go away. In an ESS system, set it to 'keep batteries charged', in an off-grid system the fastest way is to either charge / balance the battery before installation, or to fully charge with a generator if not enough solar is available to keep the batteries fully charged. | To help the batteries balance quickly, keep the batteries fully charged and the system voltage stable until the errors go away.

If you are unable to maintain the target voltage to balance the batteries without the 'high voltage' alarm occurring, you may need to temporarily enable and set the “Limit managed battery charge voltage” setting in the DVCC menu of the GX device. Reduce this voltage as necessary until the alarm stops. After sufficient time to balance the batteries, try increasing this value until it can be disabled again for normal operation. | If you are unable to maintain the target voltage to balance the batteries without the 'high cell voltage' alarm occurring, you may need to temporarily enable and set the “Limit managed battery charge voltage” setting in the DVCC menu of the GX device.
