Hi BFL13;
PF, yes, .98 or higher per KAW. Watts=VA!
I recently ran a bench test on a pair of Eaton Powerware 135AH batteries that were pulls from cell tower(s). It took 1.87KWH of charging to replace 1.00KWH drawn from the bank.
First I drew with an 800W ceramic heater until the KAW read 1.00KWH at 1:15 when I stopped the heater. The Magnum's fan was running furiously. It took the Magnum about 15min to cool down. Battery Volts rebounded from 11.99 to 12.33.
Next I used the house 120V source to recharge. At about 50min, the Magnum automatically lowered charging Watts from 950 to 600W due to the internal temperature as per the manual. The Magnum would cycle in/out of the hot condition. I shut down the test when the KAW showed 1.00KWH used at 1:13. The Magnum was in Bulk the whole time. The battery ended at 13.31V.
The next day I resumed the charging. The Magnum stayed in Bulk for another 36min and then ran 1 hour in Abs before switching to Float at 14.36. I shut the test off as the Magnum was only drawing 126W. The PF never went below .98.
My Magnum may have been exceeding its 50A rating as well. The manual says "7AAC Input current at 50A rated output", which would indicate 840W. I was seeing 950W going into the Magnum until the thermal reduction to 600W. If you extrapolate 840w to 950w then the charging might have been 56.5A
This was a bench test where there was no use of the transfer switch and no pass through of any 120V. The inverter was unplugged from any 120V to force the inverter to run the 800W heater from the bank. Next, the heater was shut off and then the charger was plugged into 120V to recharge the bank.
