Hi all. Can I configure the system to do this.

PERIOD 1
For a period during each day (8:00-11:00):
PV Panel > Export all power to grid
PERIOD 2
Then at (11:00-16:00) I want to do this:
Grid > to power the Battery as priority
When battery is full, Solar will be exported to grid and battery to power load
If wondering why... Because in this period, the grid feed rate is higher than the consumption rate.

Are these the correct settings:

That function you are using is dumb charging of battery to 100% with no fine controls at all, this is why you are seeing the grid import more electric than your house is demanding. Example 4kW grid, load 0.5kW and 3.5kW is charging your battery up in the time period.

What you need is to set a manual schedule up, period 1 will use a mode called Feed-in, please note that this will still consume some of your PV energy, as this cannot be stopped. So it goes like this... PV -> Load -> Export, so 4kW of PV, 0.5kW load and exports 3.5kW to the grid.

Period 2 will depend on your exact requirements, it seems that you wish to charge battery to 100% or close to it, so this schedule will have a mode called Force charge (or backup) to consume all your energy from the grid only.

Period 3 after 16:00 you should let us know what you are wanting to do, I presume use the battery to feed the house load during this time?

Also, when you do decide upon a schedule, make sure to set END times to 10:59 say for Period 1, as this equals 10:59:59 in the inverter

Thanks for the detailed answer. I assume you are suggesting to use the Mode Scheduler feature. I previously tried using this and had all sorts of issues. I posted to this community and I think the consensus was that the feature is extremely buggy, and not to use it.
The Mode Scheduler is a nightmare. It is different in Android App, in v1 online and v2 online. There was even a week or so when it could not be disabled after being set.
Perhaps I need to wait for the software to get more mature.

Period 2 seems to work quite well. In this period grid power is almost free, so "dumb" charging is fine.

This perhaps a better screen capture of my current settings

It can cause all sorts of issues flipping between the different access methods for sure, me and my son had trouble with Fox Cloud 2.0 app and me running Android and iPhone for him... it would take the manual scheduler and smash it (swapping values and changing operating modes)

Maybe you can experiment with just the cheap grid charge slot and see how it works for you, no need to complicate settings if the dumb grid mode works fine.

Have a little day or two testing and see how it works for your setup, with luck this works well.

Thanks so much for making time to help me.
You obviously have a lot of knowledge and experience with this thing.
I am 2 weeks in and learning. But I like tinkering, so I will keep going.
Happy new year!!

I have had my system for 10 months, you will soon learn what works and what doesn't.
And you are correct in saying there are bugs in all 3 ways to access the system, they will iron out the bugs in time.


A Happy New Year to you also.
