Sunny Island

The Sunny Island systems are suitable for systems from 3kW to 26kW is a great solution for hybrid (4048U) or all-PV (4248U) all off-grid applications which require high quality electricity based on renewable energy sources. Its reliable design with intuitive interface with integrated data logger is ideal for use particularly in special climatic conditions.

Sunny Island technology is based on advanced power electronics and state-of- the-art DSP microprocessor and is designed for extreme surge power capability. The Sunny Island can generate 3 to 4 times the nominal power for a short period of time in order to start electric motors such as water pumps and compressors.

The Sunny Island product range is compatible with the Sunny Boy monitoring systems and can therefore be integrated into nearly any SMA monitoring system. The available monitoring systems range from simple data acquisition on site to integration of web based monitoring using the Sunny Portal.
