The new OptiUse operating concept makes installation, commissioning and day-to-day use easier than ever before. The Quick Configuration Guide helps you complete the commissioning in just a few steps. And the automatic rotating field detection function shows possible installation errors immediately.
A cluster, i.e., a system with two or three Sunny Island inverters, can be operated centrally using a master device and the Single Point of Operation function. The external control unit Sunny Remote Control enables clearly laid-out remote configuration of the off-grid inverters.
The OptiBat battery management system takes care of the sensitive energy storage unit. It controls the most important charging and discharging processes fully automatically, increasing the electrical endurance of the batteries.
Sunny Island is perfectly equipped for any situation thanks to its high IP54 degree of protection and the SMA cooling concept OptiCool. It is impervious to fine desert sand, high humidity in rainforests, significant temperature fluctuations, and salty mist in coastal regions.
Even in critical situations, the off-grid system keeps running safely – thanks to the intelligent load and energy management system. The soft start function makes the Sunny Island a powerful aid when starting with critical loads with over-average inrush currents.
With Sunny Island 6.0H and Sunny 8.0H, the inverter power can be adapted precisely to the system requirements. That is the most important prerequisite for reliable and efficient operation of off-grid systems. Underdimensioned systems are often overloaded and can be switched off. If a system is overdimensioned, it rarely runs at the ideal operating point, which makes it inefficient.
Of course the new Sunny Island inverters also support the SMA multicluster technology – the off-grid systems can be extended at any time as the energy demand increases. From 3 to 300 kilowatts, anything is possible with the Sunny Island 6.0H / 8.0H.
