How to update foxess (S series G2)??
I got the latest update from the foxess agent, but I don't know how to pass it.

The S series (G2) appears to support firmware update via it's USB port, i've attached the instructions below.

I followed the instructions but nothing happening
Does the inverter detect firmware when i put the flash driver?
Can you explain for me more?
I exracted the zip file then i got this files in the picture

I'll be honest i've never used this method but I have seen the inverter go into update mode when you plug in a USB.

I would recommend you update in the order Master, Manager, Slave.

It is critical that the USB stick is formatted using fat16 or fat32 (nothing else will work)

Then on the usb stick you would create a folder called 'UPDATE'

And I imagine you then copy the entire 'Master' folder to the 'UPDATE' directory so you should now have '\UPDATE\MASTER\{firmware file]'

Double check the the firmware file in the MASTER directory has also been unzipped it should have a .HEX extension.

Plug the USB stick into the inverter and it should start the update - when complete remove the stick.

On your computer remove the 'MASTER' folder from '/UPDATE' and replace with the 'MANAGER' folder - repeat the process.

I have successfully upgraded the inverter thank you for your help

It can be upgraded by inserting a USB stick into the socket on the bottom - you will need to contact your local Fox service office to get the latest files - the post above describes how you format the USB stick and the file structure needed.

If your site is not already claimed by an agent account set one up and link it so you get access to the firmware manager.

I do a video here of the firmware update process
