1000 watt Yamaha generator?
I had an Alpenlite fifth wheel and got a Yamaha 1000 watt inverter generator when I needed a new convertor, I put in a 45 amp convertor thinking that it would be handled nicely in the rare instance wh...

In order for a three thousand watt generator not to die when starting a power factor corrected 135 amp "charger" I had to design a circuit that allows only the charger capacitors to charge, minus -any- load then go online 10 seconds later*.
To see what I mean, try it yourself -- Disconnect your converter from the battery. Disconnect from generator vac. Let the converter capacitors discharge. Then plug the converter into the generator. Hear the hiccup? It's minor when connected to a large RV generator... it's anything than minor when coupled to a borderline small generator.
Now add battery loading to capacitor charging and for those milliseconds a heck of a lot more power is being sucked up by the converter. Is the converter power factor corrected? No? Grab more paper, sharpen the pencil, wipe off the calculator.
Reserve generator power is not calculated by gradient when starting a threshold overload. The instant the motor slows down. you a screwed pooch.
*This is switched between the power supply and a 200 amp relay. It's purpose is to -verify- the power supply voltage setting and allow adjustment before going online. Capacitor loading windup is included and it is absolutely necessary.
