Had an ice storm in December , no power for 3 days, combined with a generator failure.
To this day the house where the tank was still loses power 2-3 times a week for a couple mins. Didn't want to continue investing $$$ in the tank with such an unreliable power grid.
So I shut the tank down😞. I set up another tank at home ... It's no 800 but it's pretty cool.
