Hey everyone... hope your summer has been as enjoyable as mine. (...loving the cooler than normal weather!!!) I recently installed a new pm4b 75amp charger and Trimetric meter. My batteries are 4 T...

The DC watts stay the same, VA is an AC thing.

The "efficiency" of the converter needs to be defined as to what constitutes its efficiency. Watts in/watts out is one way but now you have to adjust your VA down to watts to make that comparison.

798 in vs 646 out = 81%

So IMO your AC amps reading of 9 something is not crazy for the 45 amper.
