what are you looking to power?

 

[Roachbeef19]

Either a wave pump or return pump and a heater

anything that is powered by 12v can be connected directly to a battery with an appropriate barrel cable like these https://amzn.to/2P54XrN

if your looking to go 120v a UPS is a good option since it is always on "standby" and will take over anytime you loose power, it would do well on pumps but really no battery system will do well running a heater https://amzn.to/39MNHzt with a bit of DIY you can also expand the battery capacity of these units.

if your just looking to connect car batteries to an inverter a simple 1000w inverter will do the trick, you can have a couple batteries to swap out as needed and keep them on a trickle charger during standby

once you decide which route to go it will be easier to decide what you need, my recommendation is a larger power conditioning UPS for shorter outages and a cheap generator which can be connected to the UPS to condition power for longer outages

Here is one for diy eco tech but could be converted to any equipment if you have the right adaptors:

Whatever solution you end up with, make sure to fuse any leads from the battery. Batteries can dump a lot of current in a short circuit, which makes wires very hot, leading to things like fires.

How many amps should the fuse be?
