The 1st priority power of the system is always the PV power,then 2nd and
3rd priority power will be the battery bank or grid according to the settings.
The last power backup will be the Generator if it is available.
7. Fault information and processing
The energy storage inverter is designed according to the grid-connected operation
standard and meets the safety requirements and electromagnetic compatibility
requirements. Before leaving the factory, the inverter undergoes several rigorous
tests to ensure that the inverter can operate reliably.
If any of the fault messages listed in Table 6-1 appear on your inverter and
the fault has not been removed after restarting, please contact your local dealer
or service center. You need to have the following information ready.
1. Inverter serial number;
2. Distributor or service center of the inverter ;
3. On-grid power generation date;
4. The problem description (including the fault code and indicator status displayed on the
LCD) is as detailed as possible.
5. Your contact information.In order to give you a clearer understanding of the inverter's
fault information, we will list all possible fault codes and their descriptions when the
inverter is not working properly.
