It seems that I am not getting enough juice.
No that is not true. Your converter/charger will run just fine on a typical 20 amp outlet. What most people don't understand is that just because your converter may be rated for say 50amps DC output it doesn't mean it is charging your battery bank at that rate. Your converter will charge at a high rate, usually on the order of 15 to 40 amps until your bank reaches 90% charge. It then tapers back the amps and increases the volts. On a 2 stage charger typical of most RVs this will be around 13.6 volts and amperage dropping off to nearly nothing in the final 10% of charging. Therefore the last 10% can take several days. Unfortunately if you have a 2-stage charger your battery bank will never get the "equalization" charge that is required by most of the major battery manufactures to maintain and fully charge them. The 3rd stage of a 3 stage charger is an increase of voltage to 14.4 volts and only about 1 amp or less output to "overcharge" the batteries. This maintains their health and insures 100% full charge. Without this your batteries life is greatly reduced.
