If the LCD isn't displaying branch currents, the issue might be with the monitoring board communications cable or the secondary cable to the branch current transformer not being properly connected, or the current detection module or current transformer may be faulty. You can try replacing the monitoring board module. If the problem continues, it is recommended to contact Huawei technical support.
