....The stand-alone solar system is used where there is no electricity supply. It will normally be connected to batteries for the backup power and to utilities.

....The system components include a solar module / wind turbine, charge controller, battery bank, and an AC/DC inverter. These systems can easily be installed and ready to harvest electricity directly from nature with very low maintenance required. They can supply electricity for remote residences, roadside emergency telephones, remote sensors, lighting, health centers (vaccine fridges, EKG machines, and BP machines), radio stations, schools…etc.
