In case of a loss of electrical service to my home I have been digging around for a battery that I can plug in and leave. In case of power loss I have a full battery that I can plug into to use. Ever hear of such a thing for a small home?

Yes. It's a standard UPS -- uninterruptable power supply. It consists of a battery charger, a battery, and an inverter to power up 120vac loads after the utulity power goes off. You can buy or build them in a wide range of sizes.

Not to power the whole house. Plug in a radio, small light, maybe the smallest refrigerator I can find. Very short term use.

Jake, if you just need to power small loads like that, the simplest way would be to get the kind of UPS made for computer systems. It will not handle the refrigerator, but ir will take care for a radio and some hi-efficiency LED lamps.

Would you be kind enough to provide a link for one that is available for purchase that you would think suitable? |

Ok.. I'm going into places I have no idea about.. So I have this big heavy thing at my house that my desk top is plugged into and when the electricity fails it maintains power for at least 30 minutes or longer. It looks similiar to what I looked up online (googled UPS350). Is that what this is? Is it just a battery back up? or can/does it power small refrigerators, led lights too? Interesting but confusing to me.

Yes it gives you enough time to save data on the computer before shut down. It's just few minutes.
On APC web you can see how it works. Below model list you have green arrow change the value and do the math. But it will give you also time to charge your cell phone or walkie-talkie.

In the simplest sense, a UPS is a pre-wired battery pack with a battery charger and an inverter. This is nearly identical to the kind of solar-PV system called a "bi-modal" system, minus the solar array and solar charge controller. You can build your own; BUT, you're not going to do this, large enough to run a refrigerator, for just a few hundred bucks. You need a large enough inverter and a plenty big battery pack. FYI, the inverter you need is not JUST an inverter. It's what is known as an inverter/charger. It serves both functions and does the transfer from gid to battery power, automatically. Here's a few examples of smaller, less-expensive units: www.xantrex.com/power-products/inverter-chargers/overview.aspx |
