While I wait for the installer to get back to me on Monday
Wanted to see if the brains trust here, has seen this before?

Firmware upgrade requested from fox ess support on Friday
Thanks

It would be helpful if you could post a couple of graphs to see if the inverter is reporting loads, gen etc.. correctly

If the Force Charge is not working, what were your settings - the latest firmware requires FDPwr to be set to the charge power so if you’re following older posts setting it to 0 won’t work, also FDSoC should be set the same as MaxSoC.

I.e. Force Charge (whatever period), MinSoc 10%, MaxSoC 100%, FDSoC 100%, FDPwr (say 4000 watts).

The other thing to check if that does not work is your import grid limits have not been set correctly, you can only access them from the inverter panel (unless you have agent access) so go into Settings, On-Grid, Export Control and the settings to look at are ImportLimitPwr (should be set to at least 9900), ImportLimitCur should be set to 100A.

Thanks Dave

Have set Import current and power, they were set. But not as per what you provided

Note as I don't have PV Connected to Fox ess. Does that mean self use is not going to discharge battery if grid use is higher ?
I do wonder if a PV setting is conflicting

Some App screenshots

Here's a screenshot at 10:17 am
Which shows that the schedule has not worked
