Now, we're going to look at standard inverters. Here's one of our new style, sine wave inverters. This one is made by Zantrex, rated at 1000 Watts AC, which is really about eight to ten amps, when you start drawing off of it. It's a fairly simple device. An on/off switch and a small control panel lets you know when the power is coming in and how much is going out. We also have a place to plug in a standard extension cord, and a small fuse, in case things get too high, that will pop out. That's the front controls, and on the back, a fairly simple area, where we connect our battery. Very obvious plus and minus. This is a DC system, and reversing those will blow the thing up, and the mystery smoke will come out, so we watch our polarity. This one also has a fan on it, to keep the inside items cool. Here, we have a slightly smaller Excel-tech inverter. This again, is a sine wave inverter. We'll rate it at 250 Watts. A fairly similar setup, we've got power coming in, positive and negative, and our regular switching, and a place to plug in. This one is a little bit smaller. Again, 250 Watts, versus 1000 Watts. These are still very, varying prices. On the low end of the scale, we can come here, to a pretty much a standard UPS device that goes in offices, and is used to back up computers. We can take out their relatively small batteries, and connect them up to our larger batteries.
