| The 'Internal Error' shown in battery status is not a critical error. This only defines that within a battery system, some of the slave batteries are offline(which is due to these modules have been discharged to an extremely low SOC or being in idle mode for more than 72hrs), once the system is available for a charging activity such an error will be automatically eliminated. | The 'Internal Error' shown in battery status is not a critical error.

| The 'high voltage' warning or alarm is not unusual on new batteries that are not yet balanced. To help the batteries balance quickly, keep the batteries fully charged until the errors go away. | The 'high cell voltage' warning or alarm is not unusual on new batteries that are not yet balanced. To help the batteries balance quickly, keep the batteries fully charged 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. | 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. |

| If you are unable to maintain the target voltage to balance the batteries without the 'high voltage' alarm occurring, you may need to 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. | If you are unable to maintain the target voltage to balance the batteries without the 'high cell voltage' alarm occurring, you may need to enable and set the "Limit managed battery charge voltage" setting in the DVCC menu of the GX device.

| After sufficient time to balance the batteries, try increasing this value until it can be disabled again for normal operation. | After sufficient time to balance the batteries, try increasing this value until it can be disabled again for normal operation. |
