Cables from the batteries go to an inverter, which changes the DC to AC to run the conventional household loads. And, as the months pass, these technologies will become more readily available. Below is a variety of alternate energy components, and an overview is given of their function and how they interact in a system. You can also get a regulator that handles a greater amount of amps than currently required, if you wish to add more solar modules down the line. The next day, when the sun shines, the process starts again.
Controllers come with quite an amperage range, and a variety of options.
Controllers are also used to optimize voltage in water pumping systems, basically enabling the system to produce more water in lower light conditions by converting voltage to amperage. In a wind generator, the regulator may be built into the unit or may be stationed at the battery bank depending on how the unit is configured. Your inverter takes DC power from your charged battery bank and converts it to AC power for your typical household lights and appliances. Once you've determined the number of watt-hours a day you require, your peak loads need to be ascertained to properly size the inverter. This is the amount of watts used based on all appliances and loads that will be running at one time.
