I'm currently setting up a 120g(the money that will be invested in livestock) and thinking about how easy it would be to lose livestock from a power outage. I'm definitely buying a battery backup for the return pump and heater but wondering what everyone else is doing? Has anyone gone as far as to buy a generator? The power grid is pretty solid where I live. There are only two times in the past 16 years I can remember the power going out for more than an hour. Both were caused by wind damage from leftover hurricanes. I don't think I'll need to go as far as a generator but what battery backups do you all recommend for a budget shopper?
