Aerator back up battery for emergency

[Darlng1]

Help. I want to prepare for hurricane season . I have a 4000 gal koi pond . I have a filter of course but I’m only interested in running my aerator without electricity ; just a battery or a power station . What size powerstation and or battery should I get to run a few days. I can get a solar also or 2 batteries so I can charge one

You need to look up the electrical load of your aerator.
Then the best place to answer your question is one of the many calculators on the net for UPS sizing for computers and things.

I’m not experienced with battery back ups, but I agree with @wvned
