Load wattage calculation MPPT75 10 or 15 ve direct protocol

Hi,
Wanting to calcuate the wattage load output using the VE direct protocol data.
But notice protocol does not provide a load voltage output.

Hence only option is to use the battery voltage which on measuring is equal enough to the load voltage.

Besides the load output being switched off, any other reasons why battery and load voltage would be significantly different to each other?

Load output is powered by the battery, so output voltage will be effectively (as in, within a few hundredths) identical to input voltage!

Thanks, guessed that was the case. Just wasn't sure if somehow the load voltage might differ and be the PV in some instance.
