That in fact is how I use mine: as an emergency
, tertiary charge source on a cloudy (no solar), windless (no wind
generator) day when I need to work on the engine
or have no real need to run it for just the alternator
I have a 2000 W inverter
aboard, but if I need to run a power tool for 10 minutes, it's actually more efficient to run the Honda
and burn three tablespoons of gasoline instead of all that lossy conversion.
When it's sunny, windy and I'm running under power at five knots to pump the holding tank
three point one NM out? Fire up the ShopVac, dear, it's spring cleaning
But for short term use of 10 amps or less AC...the Honda
or equivalent units are the right choice for me. The inverter is my choice, by contrast, for running computers
or the microwave, assuming I'm OK with my battery
bank state of charge.
