Figured it out, I used a heavier ext cord to plug into 10A plug, so the voltage drop must have been too much with the lighter cord. Glad I am now charging in this frigid weather, thanks all!!
Jeff,
Glad you got it all figured out. You asked if the Inverter needs to be "ON" in order for your Inverter/Charger to charge the house batteries? The answer is NO. I also have a Magnum 2012ME MSW Inverter/Charger and I have plugged into 15A services many times and the Charger side of the Inverter/Charger has continued to charge the house batteries as normal. I don't know how much you know about your ability to control just how much your Inverter/Charger can put into your batteries at any given time but, in your Remote for that unit, you can limit the amount it puts out. That will draw less on your extension cord, even a smaller one. Just an idea.
