Deye/Sunsync inverter - battery full, still drawing from grid

[XO4001]

I don't know how to check this. The checkbox at the top is checked if that is your question.

Yes

Guys maybe this is a clue.
When I turn on the breaker to grid, the main icon menu which shows a graphical picture of where the electricity is flowing changes.

The load on my house goes to zero, like the load disappeared even tho it didn't disappear. The demand on the battery goes to almost zero. And there is NEVER anything flowing from grid. That is what's especially wierd. Even tho grid is being pulled to cover load, there is no indication of it. I have never once seen grid showing any value, and no arrows showing electricity moving from grid.

Yes

Do you have a diagram how you have all connected and CT's position?

 

[kolek]

I also don't have a CT connected. Is that relevant?

Me think so when you switch on grid.

Ok I found the box with what must be the CT. Checking the manual as to what to do with it. This isn't the source of my problem is it?

Not sure but if its not to much trouble give it a shot because I'm out of ideas.

Ok trying the 2 CT. I see how they should be connected.
Can I connect the CT to the pins with the inverter on? Or should I shutdown before connecting the leads?

2 and 4 I didn't had before it came up after a firmware update

Was your Time of Use settings working before your firmware update?

Just to be safe shut down.

Yes it was, requested a update because the mppt's where doing weird things.

So it seems like the "Days of the Week" screen is not mandatory to getting it to work.

Calling @LydMekk @robby @houseofancients @Sean123 @XO4001 in case any of you know

Did you ever set the setting from all the screenshots I provided you a couple of weeks ago in a PM, incl TOU ?
I would guess not given your question

Yes, but there are 3 issues.
1 you are selling to grid and I am not
2 you are using comms and I am not.
3 biggest problem is about 1/3 of the setting labels in your solar assistant app don't match the labels in my menus, so it's unclear what the settings are referring to

1 don't tick solar sell
2 get yourself a proper BMS, or use voltage as you wish
3 really ? Come on, this is a DIY forum, not your personal installer

I know I might come of harsh, not meant like that, but multiple folks here gave given good place to start, yet you seem to want us to configure your system for you..
We can't, we can merely help you in the right direction

I reviewed what you sent again, not seeing TOU settings.

Since you are using voltage instead on comms, you will have to convert % to voltage, which will be very iffy at best given the very very flat curves with lifepo4

Others have already posted those settings and they're not working for me. Thanks anyway.

Any luck with your CT?

Any luck with your CT?

It's 4:30AM in Japan, I'll test it and follow up tomorrow. Thank you!
