You can update your FS APP, connect ocally to inverter and it should prompt e massage regarding the upgrade of the devices.

Hi
I can connect to fusionSolar now, but I still have problem with updating the software on the inverter.

I have SUN2000-10KTL-M1 inverter with V100R001C00SPC140 firmtware, but there are many steps higher in the update list. Wich is the latest firmware? When I try to update the inverter it in a browser it only replys: Operation failed. An error occurred during device synchronization. The upgrade failed.
When I try with the FS APP it only finds the current firmware, how can I find newer firmware?
