Bought a Honda EU1000i for emergencies and outages around the house, to keep the refrig and tv running. Turns out it worked OK for the travel trailer, for battery up keep. Bought a Eu2000i, which would run the Microwave now in the Travel trailer, a good thing when wanting to fix a TV dinner, sometimes time is scarce between fishing to tie up additional necessary flies for the next day, the expense of those stor bought flies at $2.25 each adds up fast. Bought another Eu2000i so that I could pair them and run the A/C on the Travel trailer, along with the pairing cables.
Last week, I bought a portable 120 Watt folding solar panel... it's much quieter than running the gennies.
Depends, but for dry camping and battery charging, a backup plan B for cloudy, snowy or rainy days is a must, at least for me, if one can afford it. Just don't feel like hauling around a bunch of lead acid batteries, though one day, I forsee a couple of heavy 6v golf cart batteries for a 12v system.
One can lessen their need for a generators usage by conserving electricity usage, getting LED light bulbs, not using the electric pump with solar showers, solar panels and on and on and on. Just depends on how much budget and how serious you are about staying off the generator, off the grid, or off petroleum powered products that you want to be. Or use combinations, as you see fit.
A generator will always get you electrical power, a solar panel system and batteries might not always get you enough, depends on the number of watts, daylight, and your engineering ability and budget.
A honda generator, if properly stored with a dry tank and a dry, empty carburator, with no fuel to go bad in it, is usually a pull or two away from having some electricity when ever you need it. They are great to have in emergencies... plus I'd rather have one and not need it, than need it and not have one.
BTW, I bought my first generator, a used Honda EU1000I on Craigslist for $350. It wouldn't run unless the choke was on, the carb was gummed up from fuel varnish forming in the jets from being stored with fuel. I bought a can of Gum Out, pulled the panel, undid a few screws, and went to town on the jets on that carb. That pretty much cleaned it up, but the motor still "hunted" with the governor a bit. Bought some Techroline, added it to a tank of fuel (1/2 gallon) and then just ran the motor in eco mode as needed. Just running it camping, charging the battery (group 24 DC) on a one week trip, a couple of hours a day, and one tank later, the motor and carb/governor just purred like a kitten, nice and smooth.
$400 used is good, $500, to me, is too much, for an Eu1000i. Right now, there are brand new honda Eu2000i's for sale in the box on Craigslist for $900, tax free. I'd jump on one now, new if you need one, that price will be gone shortly.
