I hope someone could maybe shed some light on this watts displayed discrepancy?

While charging the battery the load watts show about 150watts lower than when not charging the battery.
Where is the missing 150watts going on the sunsynk display?
I have a kilowatt meter on the load side and that does not change, it only changes on the inverter display.
I also have a small volt/amp meter and that also shows the same result on the load side same as the kilowatt meter.

This is quite a bit of watts going missing?
Or could this be a firmware bug?
Or am I missing something else in the understanding of the display?

Battery Charging Load Shows 550watts

 

Battery Dis-Charging Load Shows 702watts

The inverter consumes some power itself, including for that nice display ... that is why you have those maximum efficiency measurements on the spec sheets. In the real world it doens't get to the published 96 or 97% efficiency though.  Your instantaneous inverter efficiency in the pic is 674 / (753 + 6) = 88.8%

Yes thanks, I figured as much that's why I did not come back to this post
Been running for a week now and overall its performing quite well.
Eskom bill down from average 30 units a day to less that 10 per day (Been cloudy all week) so that leaves a warm fuzzy feeling
