What are off-grid systems with Sunny Island inverters?Off-grid systems with SunnyIsland 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., SunnyIslandCharger). The SunnyIsland forms the stand-alone grid as a voltage source.
Can a sunny island inverter be used on a stand-alone grid?The AC sources must be suitable for stand-alone mode with SunnyIsland (see technical information "PV Inverters in Off-Grid Systems" at ). The maximum output power of the AC sources in a stand-alone grid must be observed (see the SunnyIsland inverter installation manual). The SunnyIsland uses batteries for energy storage.
What should I do if my Sunny Island inverter is off-grid?Ensure that the off-grid system cannot be reconnected. Open the enclosure lid on the SunnyIsland inverter and ensure that no voltage is present in the device. Ground and short-circuit the AC conductors outside the SunnyIsland inverter. Cover or isolate any adjacent live components.
What is a sunny island inverter?As a voltage source, the SunnyIsland inverter forms the stand-alone grid. The SunnyIsland inverter regulates the balance between the energy that is fed in and the energy that is used and features a battery, PV array and load management system.
What is the difference between Sunny Island and off-grid systems?The SunnyIsland forms the stand-alone grid as a voltage source. The SunnyIsland 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 SunnyIsland are single-phase or three-phase AC distribution grids.
How do I install a sunny island off-grid system?The off-grid system must be installed according to the circuitry (see Multicluster-Box documentation). In the Multicluster-Box, all SunnyIsland circuit breakers must be open. As a result, the SunnyIsland inverters are not connected to an AC source. The SunnyRemoteControl must be connected to the master of each clust
