Just finished wiring the 20A/TV+outlets to the inverter and everything works like a champ! I ran the A/C for 10 minutes no problems.
I didn't have a plug to connect the 15A/outlets yet but I don't foresee any problems.
Your solution is perfect. Like you mentioned, this application will limit me to 750W inverted power...which is way more than I will ever need to charge phones/tablets and watch TV. The A/C and microwave are the only high wattage appliances I ever use and those are not running through the inverter so 1500W shore power in not an issue.
I connected the convertor back and left the breaker off. If I need fast charging of the batteries, then switch the breaker to the APC750 off and switch the convertor breaker on. When done, reverse and I'm back in action.
THANKS FOR YOUR HELP AS WELL AS OTHERS WHO HAS HELPED
