Off-grid systems with Sunny Island inverters are self-sufficient utility grids that are being fed with energy from several AC sources in the stand-alone grid (e.g., PV inverter), from a generator, and/or with DC charge controllers (e.g., Sunny Island Charger). The Sunny Island forms the stand-alone grid as a voltage source.
The Sunny Island forms the stand-alone grid as a voltage source. The Sunny Island regulates the balance between the energy fed-in and energy used and has a management system with battery and generator management and load control. Off-grid systems with Sunny Island are single-phase or three-phase AC distribution grids.
While mentions of large tied-grid energy storage technologies will be made, this chapter focuses on off-grid storage systems in the perspective of rural and island electrification, which means in the context of providing energy services in remote areas. The electrical load of power systems varies significantly with both location and time.
The off-grid system must be installed according to the circuitry (see Multicluster-Box documentation). In the Multicluster-Box, all Sunny Island circuit breakers must be open. As a result, the Sunny Island inverters are not connected to an AC source. The Sunny Remote Control must be connected to the master of each cluster.
Off-grid energy storage, specifically battery technology, is a crucial asset to satisfy electricity needs of individual households, small communities, and islands, as discussed in the chapter.
The Sunny Island regulates the balance between the energy fed-in and energy used and has a management system with battery and generator management and load control. Off-grid systems with Sunny Island are single-phase or three-phase AC distribution grids. The local standards and provisions must be observed.
