Off-Grid solar energy systems
There are several different types of off grid solar power systems. The first type of solar energy system is one that would typically be used in a caravan or boat and would typically be a ELV system running either 12 or 24 volts of Dc power to specific appliances. The second type of system which is more common in a residential applications is a solar system that uses a charge controller and inverter and creates a standard 240 volt AC grid output. This means houses can use standard off the shelf electrical appliances. Modern inverters such as the Sunny Island from SMA incorporate functions of both and inverter and a charge controller and regulate the relationship between the various components in the system.
