I have searched fox ESS and the web in General, but I can’t find any reference to the latest firmware versions for Foxess inverters. Specifically I have a KH10 inverter. Anyone know.

Also, how do I get updates?


KH10, 24x435w panels, 20kWh of ECM/C4300 battery’s.

I'm new to this but today I added 3 EC2900 V1 Batteries to my array.
I noticed that the firmware version was different on the new batteries. The original batteries have a Version of 1.12 and the New batteries have a version 1.09. I reached out to https://theecosupermarket.co.uk on 02476 981 489.
The assistant told me that, either my installer could update my Firmware of Fox could remotely. I called fox on 02475100078, this is mainly an installer number and you'll be asked to email. I've just left a email, service.uk@fox-ess.com, asking if they could update my firmware remotely.

I hope this helps.

I've found that opening a support ticket here works well too : https://support.fox-ess.com/portal/en/newticket
