Hello community...
I am from Germany and run a Deye Sun-12K-SG04LP3-EU inverter with 10Kw solar panels attached and also 4*Deye R"-M6.1 batteries.
I also have SolarAssistant and this connected to Homeassistant using MQTT so have sensors and switches in Homeassistant. On top I have hourly based electricy price plan (using the provider Tibber) which is integrated into Homeassistant as well.
During summer times my PV poweder charges my batteries pretty well and I run all load from those/PV March-September. The additional PV power I sell to the grid.
Currently all works flawlessly but with winter approaching my PV load cant' handle charge, or even load, anymore and I want to use reasonable Tibber electricity prices to charge my batteries fully up and use the battery power for the rest of the day.
My challenge is on how to enable grid charge at all with settings on battery and work mode to be done properly!?
I have set working mode "time of use" enabled since starting with the inverter and all worked well
now I had to set working mode (SoC is at 20%) to off and Grid Charge to ON and battery started to charge (which is fine)
However I want to use the battery and I saw a Youtube video telling me "time of use" in work mode as to be enabled at all to use the battery power!?
What I ask for my situation should be straight forward but I am struggling a bit and wondering what to set so I can later on create a HomeAssistant automation to enable/disable Grid charge when Tibber electricity prices are below 50% daily average.
I attch my setting which currently work to charge from grid, having said "time of use" is disabled and I think that's wrong!?
As you can see also the weather is bad and battery stopped serving load last evening and switched to grid completely (which is fine) at 20% SoC. Now it's back at 23% after enabling grid charge and disablingn time of use...
