I think i know what he is saying
The cap goes across the megawatt input,
It will be charged when you hold the pushbutton switch closed
It will be charged at the RMS voltage level
It is NOT going to go from zero to 178 back to zero
The stored RMS 120v will add Momentary starting current to input/, induction circuit of the mega watt, allowing a small generator to energize the circuit and charge batteries
It's not the 700w charging that stops an 800w generator, it's the inrush current very similar to starting an induction motor like a compressor
Since a run cap is designed to be left in the circuit, using it as a momentary start cap will not hurt it, and if needed , it could be hard wired to the mega watt and left in the circuit,
The input of the megawatt becomes an LC load circuit, not just An L load
I am sorry, but what you are saying about the capacitor is simply not true.
The voltage across the capacitor is and must change 120 times per second!
First Half Cycle ...
The voltage across the capacitor ramps to +170 Volts peak.
Then it ramps down to 0 Volts.
Second Half Cycle...
The voltage across the capacitor ramps to -170 Volts peak.
Then it ramps down to 0 Volts.
These two half cycles will repeat 60 times per second while the button is pressed.
The Voltage is AC = Alternating Current, NOT DC.
The capacitor charges and discharges 120 times per second.
Nothing that you say, can stop this from happening.
Nothing.
