Generator size for Megawatt PS?
Hello all, I've been lurking on this forum for quite some time, but recently registered - mainly to ask this question! I'm looking at the larger (36/41 A) Megawatt, and am wondering what the minimu...

WITH the 36/41 amp Megawatt...
Power it up and the 120 vac lights DIM for a moment. On shore power and Mexican house wiring.
WITH 50uf of motor run capacitors. No dimming. Not even the faintest flicker.
The capacitors and inductor in the PS take a big bite inrush to power up. Enough to kill a marginally sized generator. The caps help reduce this.
Wire the caps parallel with the line before the switch that powers the power supply. The caps have to power up before power is sent to the power supply. Vendors like Surplus Center in Nebraska sell motor run caps cheaply. The more the merrier. 100uf is not "too much". Gang them, put plug and socket pigtail connections, wrap it all up in Gorilla Tape then start spraying the lump down with Varathane. Coat after coat. 14-gauge wire will do fine. Works like a champ for any high inrush load including motors, chargers.
