Whether this is good from a practical standpoint, however, is doubtful. We have used the machine for lights less than 10 hours in the past 15 years we have owned it, and between the $800.00 cost of it, and the fuel consumed keeping it ready, it really looks like a poor investment. A battery storage system and solar panel would make more sense, but with a generator already paid for, and the limited demand we have seen, even that investment doesn’t look good.
Yeah, sure, why not? During some emergency situation a generator can be very helpful. I recommend to check out this guide https://bestgenset.org/ for different options and to be on the safe side to purchase one of the variants for a home use.
