Battery backups for sump/powerheads

[Belegul]

Can anybody out there recommend a battery backup system for me? I'm planning on using an eheim submersible pump in my sump, with koralia evo power heads in the DT. My concern, and feeling I need a backup, is because in the year I've lived in my new place, I've had four power outages, one of which was nearly 24 hours long...

I don't want to kill my pretty fish! Any help would be greatly appreciated!

I do not have a personal generator for my house, btw. Thinking about buying one in case my power goes out for a long time in the Minnesota winter, but don't think Id run the fish tank on it... Probably would save the wattage for ings like... Oh, the furnace

The generator would be the way to go. A really high end battery backup will cost almost as much as a generator.

I use an Tripplite APS700 (NOT APC!) hooked up to a couple of deep cycle marine batteries - works much better than a PC ips as you can have a chain of batteries hooked up. For a 700w unit it costs about 300+batteries. This unti works like a UPS (charges batteries, runs on mains power) until the power goes off, then uses an inverter after that.

I have a generator, but the power never goes out when I'm here - this gives me 8-10 hours of runtime on the critical equipment - enough so I can get homne and sort out, or at least bring the gen up.

To run pumps safely, you need a UPS that will emit pure sine wave, rather than a stepped approximation. This unfortunately puts you into a somewhat expensive bracket of UPS models. For example, the APC SmartUPS series emits sine wave, while the BackUPS series does not. The cost difference is quite substantial.

I use an APC SmartUPS 1000.

I also use the APC Smart UPS 1000. It gives me 8 hours for two Koralias and a powerhead in the sump. After that I have a Honda 3000 power plant.

Thanks for the input all! Not what I was hoping, but it was what I was expecting Any other tips/tricks would be welcome, if there are any. I'll look into the APS and APC.

Same except 2 of the same UPS and a Honda 2000
