If your Axpert Inverter displays a 09 fault, it indicates that the DC-DC module is damaged. You can repair the main board or replace it directly.
What to do if my Axpert Inverter shows a 56 fault?
If your Axpert Inverter displays a 56 fault, it means the wire connection or fuse was burnt. You can repair the main board or replace it directly.
Why is my Axpert 3KVA-110V not working and has no display?
If your Axpert Inverter is not working at all and there is no display, the SPS module is likely damaged. Replace the main board to resolve this issue.
