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

DIY Ecotech Battery Backup for $60
I’m going to be showing you how to make a battery backup with a group 24 deep cycle marine battery, which cost roughly $80, and are rated at 75 ah. You might be asking yourself why such a large battery, when the standard 18AH battery can last 20 hours on a MP60, 36 on a MP40, and 72 hours on a...

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.
Simple, Effective, Expandable Reef Tank Battery Back Up System
On a different forum I shared my battery backup system and figured I would add it here to help anyone looking for a solid setup. Yes, there are many ways to do it, but from my research UPSs are unreliable and only last a few hours depending on the model. Some aquarium product manufacturers...

How many amps should the fuse be?
