What IS the relationship between state of charge SOC and AC frequency ?

As far as i can determine this isnt actually documented (properly)

(from memory the docs mention "approaching full" of something along those lines)

Also.. and to add more confusion, Ive recently noticed with a BYD lithium system that the frequency shift only happens once the batteries are reporting 100% SOC. And not before.

We are trying to configure frequency controlled switches in line with the Quattros frequency ramp on SOC

There is NO relationship between the the SOC and Frequency in the standard system.

however if you add the assistants that control the frequancy shift then these assistants control when the quattro shifts frequancy, but it will only do this when the solar is outputting more power than can be consumed by loads or battery charging, so once the battery voltage rises above set figures then the quattro will adjust the frequency up as stated in the assistant . this is voltage based not SOC based
