My system around 400 gal includes a 180 gal a 125 gal a 75 gal and a 90 gal sump.
I have a small generator for any lengthy Power outage.
I have a Toyota Tacoma and it came with an inverter built into the Box. I have a heavy duty extension cord that I run from the truck in my garage to the tanks.
I then run 1 heater and my amp master return pump for 10 - 15 min every 2 hours to help nurse the system until the power comes on. Living in the lower Mainland I do not have to worry about -20 or -30.
You most important issue is some kind of water movement as the water sits the salt (being heavier than water) content drops to the bottom of the tank and suffocates your fish and corals.
Remember your plan is only effective if you test it and it works, so once or twice a year testing for a power outage will give you peace of mind.
