Stand-alone grid function

Off-grid systems with Sunny Island are used to set up self-sufficient utility grids. The Sunny Island X forms the stand-alone grid as a voltage source. The Sunny Island X regulates the balance between the energy fed in and energy used and features a management system that manages the battery, generators and loads. AC sources (e.g., PV inverters) supply loads and are used by the Sunny Island X to recharge the battery. In order to be able to increase the availability of the off-grid system and reduce the battery capacity, the Sunny Island X can use an external energy source (e.g., a generator).
