Hello all
I have set up my mode scheduler on foxcloud2.0 but have been tinkering with the settings as I am not really sure what each of them actually mean or does. Can someone please explain?
Min SOC
Discharging Cutoff SOC
Max SOC
Discharge Power
What I am trying to do is force discharge at 4pm til 4:35pm but stop dicharging if the battery drops to 60%.
I have also noticed that some days the Sicharging cutoff seems to change itself to 10%!!!!
The firmwares are currently being worked upon by Fox, as the FD Soc that should stop the session is not being honoured. So you are going to find it difficult to get it working as you want currently.
The one setting you have to be careful with is your discharge power of 5000W, this will be taken very literally. So if you have a 10.5kW inverter, and set this to 5kW, the it will only create 5kW of AC power. If you demand 8kW for house load, then it will not be able to create this, and will most likely pull 3kW from the Grid during this demand (5kW from inverter)
The future behavior that Fox are working on for a while now, is you set a 60% cutoff value that you like, and once this is achieved, then it should swap work modes to your default. Right now it drains to 60% and will then pull power from the PV or worse, the grid until the time period ends.

Hi Me again
I have changed the min SoC from 60% to 10% thinking that during the forced discharge the battery will stop discharging when it has dropped to 60%. But during this time if the house Load increases higher than the panels are producing the battery will feed the house until the Min SoC reaches 10%.
This has not been the case.
If the load on the house goes up during the discharge and the battery has already dropped to 60% then the house then imports from the grid!!!.
How do I set the scheduler so that I can force discharge down to 60% but if the house needs power it can still draw from the battery?
Please help this is doing my head in

It drives me a bit nuts too but this is exactly what materialbarracuda is talking about above. The behaviour you’re looking for doesn’t currently happen.
What I do is calculate how long it should take to force discharge the amount I want to dump and set that as the time period. I then set a slightly lower discharging cut-off SOC as a back stop. It then discharges for the set time period and gets somewhere close to my target before it gets to the cut-off SOC, and so does not take from the grid.

Thank you Sarah
Not the answer I was hoping for but at least I know it is not just me

Hopefully Fox will come up with something soon. In the meantime, I’m considering creating a spreadsheet cos the maths is doing me in 
Until they do fix the firmware behavior, I discharge based upon time.
I worked out that for me, 1hr of discharge in the morning (from 100% overnight) takes me down to roughly 55-57% SoC.
Makes room to store the excess PV that exceeds my export limit, so I don't clip the PV output.
Once you know the time to % values, you can quickly plug in a time value during discharge.

slowly getting to learn some of the nuances of solar energy.
I am in the UK with Octopus and peak rate is between 4 and 7 in the evening.
If the battery stops feeding the house once it has reached the cut off discharge number of say 60% what is the point of having a minumum SoC in the settings?
