My solar system was recently installed. It is a Fox ESS H1-11.4-US inverter + G2 Hub. Currently no batteries (they will be added sometime in the near future). The issue I'm having is that every few days the inverter goes offline in the app (it is still working though, producing energy). The G2 hub and data logger remain online and I can see the solar production from the app dashboard. If I power-cycle the hub & inverter it comes back. Any ideas or suggestions?
Without batteries which provide the operational power when there is no solar, it’s likely it is going into standby - but you would expect it to recover when there is sufficient solar. Probably a good place to start is checking that you have latest firmware and upgrade them first.
Sorry, should have mentioned that the system is grid-tied and the inverter goes offline even without any grid failure occuring.

Ok thanks - whilst the inverter is grid tied, it doesn’t take any power from the grid 9unless you have batteries which are charging from grid), it just biases itself to remain grid synchronised. The rest of the time it uses DC power i.e. solar or battery to maintain most of it’s operations, and without that you cannot guarantee it will stay operational 24/7.
Your ARM is up to date, i’m seeing 1.21 for Master but that version may be local to your location.
Might be worth raising a ticket with Fox directly, let them know what you are seeing and ask them to check your settings and confirm you are on latest firmware.

Interesting ... but if the inverter does not take any power from the grid then wouldn't it go offline every evening when the sun goes down (which isn't the case)? Also, something new to report ... if I wait long enough it seems that it will go back online without power-cycling everything. I'll leave it alone from now on and see if there is any pattern to it going online.
Thanks for your replies!
