When the batteries are full or even if they are not quite full, with these big wires here, the energy runs to this inverter. The inverter is an electronic and electric unit that is able to use the 24 volts that are going in here and then changing it from a direct current, what they call DC, to Amplitude current, called AC. An outcome, here, is what you use for your house. That's a normal switch, that's a normal plug here, where we have out light in here. So, in a moment we are working with solar to get the light in here and to show you that it's so easy to store the electricity in batteries, to convert it to the power you want to. This one is 110, this black box, here, we brought with us from Germany, and this one will convert not to 110 but to 220 because that's what we use over in Germany. Then it goes up there to the house and we have our plug-ins and you can run your TV and your computer and your everything. What is not using too much power, you can run on solar. And, this way, usually when you have weather like today, beautiful sunshine and wind, we use no electricity from the grid at all. Grid, the grid means, the grid is called what the electric provider is providing to you. So, in a moment our meter does not run at all because all of our electricity for the freezer, for the refrigerator, everything comes out of the batteries. When we have bad days, what happens too, there is no sun, no wind, then about after two days the batteries are empty. So they shut down by themselves, nothing can happen, but then we need the power from the grid. And so, we have an electricity bill and what we pay for electricity a month is sometimes $2, sometimes $8, sometimes $12, but in average we are about $5 to $7 a month what we pay because the rest of it we get from our solar and wind energy.
