Fault Description: The power station data is not displayed in the web client or app client, and the communication fails.
Cause of failure:
1 The data logger is not installed correctly, resulting in a connection interruption
2 The data collector traffic subscription may have expired. It expires every year
3 The power station settings may be incorrect, leading to communication issues.
4 The inverter communication circuit or data collector components could be damaged.
Judgment criteria: Please eliminate the installation problems by yourself, and contact Hua Yuxin customer service staff to help solve the rest of the situation
Solution:
1 .Check and verify that the data collector is securely and correctly installed without any looseness.
2. Provide the SN code of the data collector to the customer service staff to check if the traffic subscription has expired. If it has, contact the communication supplier to renew it.
3. Provide the correct monitoring account and password to Hua Yuxin customer service for troubleshooting.
4. If the issue is not related to the installation or settings, contact Hua Yuxin customer service to replace the data collector or inverter and update the monitoring website accordingly.

1. Please double-check that the access password for the router is accurate, and be mindful of any uppercase or lowercase letters. The password type should be WPA/WPA2-PSK, with a length of 8 to 31 characters, and no special characters like &, =, %, +, ", or.
2. If you have previously altered the name or password of your router's wireless network, try to reconnect to it.
3. Attempt to move the router closer to the inverter to ensure that they are within the effective range.
4. If your home has multiple routers, ensure that each router has a different wireless network name. If there are identical network names, modify them.
5. Verify that the router's advanced settings have not been modified. If unsure, consider restoring the router to its factory settings.

1. Refresh the router list
2. Attempt to move the router closer to the inverter, make sure there are no metal objects obstructing the signal between them.
3. Check and confirm that the router has not been set up with advanced settings. If the user is unsure whether advanced settings have been made, the router can be restored to factory settings
4. Confirm that the router supports the WiFi 2.4GHz frequency band, and the wireless signal covers the location of the inverter

1. Check and confirm that the inverter has been powered on and running, the Wi-Fi module is installed firmly, and the RUN light is on.
2. Try moving your smartphone closer to the inverter to see if you can successfully detect a signal.

1. When personnel are not present on-site, the equipment can be remotely shut down using the mobile phone APP.
2. When personnel are on-site, an emergency shutdown can be performed by operating the local emergency stop button.

If the device is connected to the internet:
1. Use the APP or cloud platform to switch and adjust the working mode of the energy storage machine.
2. Select the desired mode from the available options and save the changes
If the device is not connected to the internet:
1. Use the dedicated mobile APP to directly connect your smartphone to the energy storage machine.
2. Switch and adjust the working mode of the energy storage machine. Select the desired mode.

Self-consumption mode:
In this mode, the system prioritizes power supply to the load in the following order: PV (Photovoltaic) > Battery > Grid. It means that the system first uses power generated by the PV panels to supply the load. If the PV power is not sufficient, it will supplement the load with power from both the PV system and the battery. If the combined power is still not enough, the grid will be utilized to meet the remaining power demand. This mode maximizes the use of PV and battery power while reducing reliance on the grid. Any excess power generated by the PV system can be fed back to the grid.
Within this self-consumption mode, users have the flexibility to set up to 6 time periods for battery charging and discharging. This feature allows users to optimize battery usage based on their specific needs and take advantage of time-of-use pricing.
2. Off-grid mode:
When there are issues with the power grid, such as instability or disruption, the inverter will automatically switch to the off-grid mode. This transition occurs within a rapid switching time of fewer than 10 milliseconds, ensuring that critical loads can continue to operate safely without relying on the grid.
The off-grid mode also provides users with the ability to configure parameters related to off-grid backup. It can be seamlessly integrated with the DOD Holding function, enhancing its versatility and suitability for various applications.

1. Confirm whether the meter installation location is correct;
2. Confirm whether the meter CT (current transformer) installation direction is correct;
3. If there are no issues with the above, promptly get in touch with your service provider or installer for further assistance.

1. If the inverter is connected to the internet, log in to the APP or web interface to check the inverter's historical alarm information to identify the type of fault.
2. If the inverter is not connected to the internet or there is no available local network, use the local connection feature in the APP to access the inverter's historical alarm information and identify the fault type.
3. Please report the alarm information to your service provider or installer and, if permitted, shut down the battery.
