Problems with yamaha ef2000is generator

I have the Honda Eu2000i and the same problem. I noticed that the converter drew 1290 watts and my very small 900 watt micro drew 1150 watts. I opened the wire to the converter and put a 3 way light switch in the circuit: connect the 120 v supply (the original wire to the converter) to the common terminal, micro line to line 1, and converter line to line 2. I used a flat paddle switch so it didn't protrude from the wall very far. I made the top portion of the switch go to the micro which is high in the camper and the bottom go to the converter since it is located near the floor. Now my Honda hums away at idle until the micro is switched on. It then speeds up to maybe half throttle and the micro cooks properly. You need to keep the paddle switch in the converter position until the micro is needed or your batteries won't charge. All the lights in my camper are LED's so they are basically no load. The water heater and fridge need to be on LP or again, the gen set could be overloaded.
