FoxESS H3-10.0-E Load metering - incorrect registers?

[Szpero]

Inverter: H3-10.0-E
Manager: 1.91
Master: 2.19
Slave: 1.03

Changed registers works also with:
Manager: 1.85
Master: 2.11

What "Load Power" should show for the user? Inverter power lost during work or home consumption?

For me Load values seems odd and only above 0 when any kind of AC/DC conversion is active (battery/pv to grid for example).
Maybe it is just energy waste. I switched code to different registers and values are much more realiable.

31127 - Total load
31029 -> 31129 - R load
31030 -> 31131 - S load
31031 -> 31133 - T load
