I am a bit confused how the reading at the cable ends is 12.6V when they aren't connected to the inverter if there is a wiring issue. Is it because my voltmeter doesn't put any load on the circuit? I'm not an electrical expert so this is baffling to me. I just assumed that if I measure 12.6v at the cables when they are not connected to the inverter that once they were connected there should still be 12.6v supplied...and the loss is coming inside the inverter, not from somewhere between the batteries and the inverter.  |
You are exactly right - a voltmeter draws almost no current. The inverter, even in idle mode, draws much more current than the voltmeter. That current is causing the voltage drop across the high resistance connection. V=IR
