Hi, thanks again for adding the soc of the 2nd battery. The output for the 2nd battery doesn't contain the voltage and ampere, so the power use of the 2nd battery can't be calculated. Or is there an other way to calculate the pbattery2 value out of house_consumption value?

Hmm, it seems inverter does not report 2nd battery voltage/current, there is no known register with those values.
And the house_consumption is calculated value (from pbattery1 register) ...
I'm afraid there's no help at the moment.

Register 35264 (signed32) is power of 2nd Battery. 47924(U16) is voltage and 47925(U16) is current. Could you please verify and implement this?

Hmm, where did you get the 35264 register description ? I do not have it in any of public/not-so-public sources
