My new UPS

Post by **Red Squirrel** » Sat Jun 02, 2012 4:33 am

I wanted something that can run my server equipment for hours, not minutes. So I found an inverter-charger on ebay (made by Tripp Lite) and bought a couple batteries:

I may be adding more as they are so cheap for the power they give. The current setup as is will run 300w for about 5 hours. I did not hook it up to my production stuff yet, I still need to do some changes such as get some kind of battery enclosure. Thinking a Tupperware container with some vents cut into it. A hydrogen sensor is also a great idea for piece of mind.

Inverter/charger?

So, does this device invert when the power goes down, otherwise, it charges the batteries?

I could use something like that for a sump pump backup.

Can you explain it more?

Maybe a better picture of the inverter?

By the way: They make battery boxes for boats.

Yep when the power is on, it keeps the battery topped up, like a regular trickle charger, when the power goes out, it immediately switches to battery/inverter just like a UPS.

This is the unit here:

(that one is higher capacity, but same idea)

There are different types/voltages as well. Would be great for a sump pump as it would give you decent run time.
