We do a fair amount off grid and rely on solar panels. We've just returned from a THS at Bridgnorth where we had a great quiet time but struggled on Monday for power. Monday was very cloudy all day with lots of rain. I'd run the onboard battery down on Sunday night (11.8volts) watching telly (23watts). On Monday it failed to get about 12.2 volts with 170 watts of solar panel. I'm thinking of buying a generator for emergency use. If one would run the boss's hair dryer that would be a bonus. Any suggestions please?
