I don't get it: Battery level (nominal) #182
Comments
The Battery level is the real usable battery percentage, if you set min SoC to 10% and max SoC to 90%, 80% of the battery are usable. If the battery is 50% charged, that then makes the Battery level (nominal) 40%. |
elektrinis, can you join the discord channel (link at readme page) to discuss the temperature issue? As far as I remember your issue is very old and I guess we can better discuss this in a chat |
I'll join when I have some spare time, thanks for inviting. About the SOC. I'm perhaps misunderstanding the idea, but... My battery was set to 0/100% limits and charged fully. After I set upper limit to 90%, and if battery is still charged to real 100%, I would expect this 'normalized' value to show 111%, and not 90%. It seems to be in reverse? |
The inverter unfortunately doesn't publish the real SoC, just the relative one. |
elektrinis, can you poste a screenshot of these two entities in comparison? In my case I have set min Soc to 9% and max Soc to 92 %. So these values are kind of reasonable in my case. just found this in a SH8RS datasheet. https://www.rpc.com.au/pdf/sungrow_SH8-10RS_manual.pdf Should we rename it like this? |
Did a quick test now when actual real battery SOC was 92%. Lowered |
OK guys, after staring at it for some time, few hours later I think I'm starting to get it. I was confused with the "nominal" term and the fact that inverter caps it at 100% and behavious becomes weird when min/max SOC is adjusted has fueled the confusion further. But now this makes sense. |
Unfortunately, I still don't get it... Is the "nominal" value an estimated calculation made by this integration and nothing with that name is actually coming as data from the inverter? How can we confirm that setting min and max SoC actually works? And what is the difference between min SoC and reserved SoC? If I set min SoC to 5%, reserved SoC to 20% and max SoC to 10%, do I have 65% usable capacity? What exactly would a SoC of 0%, 20% or 100% under these circumstances mean? |
Describe the bug
Just loaded the latest code.
Battery is 100% charged (real 100% when soc limit was set to 100%)
SH10RT connected via internal LAN.
Latest firmware
Latest HAOS
extra issue: inverter temperature is Unknown (same as before)
