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...

So, 46.5a X 13.9v = 646.35w / .63eff. = 1025.95w / 104.5v = 9.8a should read as:

46.5a X 13.9v = 646.35 VA / .63eff. = 1025.95 VA / 104.5v = 9.8a, correct?

So how do I compare that to Wattage?


All DC voltage calculations power calculations have units of watts.

AC calculations have units of VA for the power supplied by the source, and W or VAR (Volt-Amp-Reactive) for power delivered to the load.

Reactive power increases the supplied current and is not desirable.
