Battery capacity scale or unit wrong? #72

Hi,

I am testing a little bit around with my battery and backup settings. I have found, that I must have a really huge battery. Entity sg_battery_capacity tells me a capacity of 12.000 kWh. 🙃 Maybe the scale factor or the unit is wrong. Connected is a HVS 12,8 kWh battery. Solutions could be

change the scale to 0.01
change unit to Wh I could not find the source for this register. It's not in the Sungrow Modus description. So I am unable to verify which one is the correct solution.

Maybe someone could help how to fix the entity definition

oh, you are right. In my case the battery capacity returns "14,400 kWh"

... damn ',' vs. '. ' ... mixed them up...., again ;)

I saw the register definition in a german forum. I guess it was iobroker or https://www.photovoltaikforum.com.

Have no time to test at the moment. If you could do a PR, this bug will be fixed sooner :)

Found the source for the register definitions: photovoltaikforum.de Scale should be 0.01.

Now capacity has correct value.
