FoxESS Community - Owners & Installers Forum

I have had my Fox system for over 6 months, it has been working fine. About 2 weeks ago forced discharge stopped working. I raised a ticket with Fox UK help desk and a couple of days later it was fixed.

Last Thursday 28th it stopped again so i raised another ticket. I was contacted yesterday to say they had updated the firmware and it should now work.

Unfortunately it still doesnt work. i have notified Fox, but no response so far. I contacted the company who sold me the slave batteries and they said it could be a problem with the inverter. They told me essentially to turn everything off and sent me the FOX instructions, this didn't fix it.

The interesting this is that the phone app actually states that the system is doing forced discharge in line with the scheduler, but it isn't discharging at all. Forced charge works fine.

If anyone has any advice I'd appreciate it, I will keep trying to get a solution from Fox, but maybe I need to talk to the company who installed the inverter and intitial batteries; Soly?

Have a look at this post, it's a possible reason after recent firmware updates viewtopic.php?p=12377#p12377

Hi Dave,

Thanks!

Where do I find these settings?

Web app?
Phone app?
Inverter itself?

You should check your G99 certificate for the correct value for export.
In my own example, 7kW inverter with a 3.9kW export limit.

I can’t find that but I have a 6kw H1 and Dave said it’s 6000
