Those aren't useful numbers but I'm no expert. 100 ft extension cord, 104 volts and still delivering 45 amps? Come on.
I had similar line input current readings when running directly thru the inverter over short heavy cabling (about 2' of 2 awg). I used the kill-a -watt to confirm what I saw on the inverter and trimetric displays. In either case, this thing pulls over 9 amps to deliver 46a at a relatively low output voltage of less than 14v. The pm4-45's are rated at a max input current of 5a, and the -55's are rated at 7a. This thing doesn't come close to those ratings. ??? Are the pm4b models way less efficient by design? If so, they should sell for about $30.
Add to this the fact it does not reach the Vabs set point until batts are near full, with amps tapering, all the while. Does this look like any 3 stage converter/charger's charge profile you're familiar with? Whatever happened to amps tapering once/after the Vabs set-point is reached? (It does however seem to resemble the VEC1093's profile).
