Normal home service is a 200 amp panel to supply everything. Normal 15 amp circuits are about 2000 watts. A little gas generator would supply one circuit or about 2000 watts and a bigger portable generator might do two to four circuits. Are we talking a 12 volt car alternator trying to invert to 120v alternating current? Just a little confused by all this and why you’d want to use your car anyway instead of what has become a standard way to power up in emergencies.
Speaking of DC versus AC, anyone see Current Wars yet on Edison DC fighting Tesla AC back in the good old days?
