Sunny Island SI-2012 & 2224

The New Sunny Island 2012 and 2224 extends the product range for the lower power sector. 

The new devices not only include the well-known features of the big brother Sunny Island 5048 but with lower weight and reduced size make these new inverters even easier to handle and install. The high protection class IP54 and the Sunny Remote Control (SRC-1) give you full flexibility for the installation location.  The integrated data storage and update feature via SD card results in additional user and service friendly operation.

Easy to use technology at its best: the unbeatable combination for off-grid systems of up to 9 kilowatts.

Data Sheet

Powerful inverter/charger for stand-alone or grid back-up operation which can be stacked in clusters for high power levels in both single and three phase networks. High power (up to 6.5kW for 30 min); high efficiency (> 95%); low standby & idle consumption (25W/4W).

Designed for rough ambient conditions. OptiCool system gives high power in temperatures up to 40ºC by cooling the encapsulated transformer but keeping air ventilation away from coated circuit boards & electronics to ensure high protection for humid or salty atmospheres.

Includes two free programmable relays per unit to enable load shedding or other use and timers to enable daily, weekly, or monthly functions.
Integrated MMC/SD memory card reader to enable updates, transferring of parameter settings, for storing error/events lists , or data logging.
In stacked cluster or multi-cluster systems all settings are made at the main unit which gives automatic setting of parameters in slave units allowing easy programming and update.

Multicluster Boxes

Install large off-grid systems with minimum effort. 

The new Multicluster-Boxes for the Sunny Island 5048 are the ideal solution for the easy installation of island and hybrid systems from 30 up to 110 kW. 

They include integrated generator and load shedding contactors for AC distribution.

For an example of Multi-cluster boxes in use see Isle of Eigg project.

Gen-Man

Allows generators with more than 2-wire start to be interfaced with 2-wire start inverter control. Controls warm-up & cool-down times of the generator.

Product Code: SI-GENMAN

 

Battery Fuse Case

Double pole fused disconnectors. These protect the cables from the batteries and allow easier maintenance of the inverters and simplify installation.

Product Code: SI-BATCASE.01 etc..

Frequency Shift Power Control (FSPC)

In a Sunny Island system if wind or solar generation exceeds the power required by the loads the battery will become fully charged. To prevent the battery overcharging, the Sunny Island increases the grid frequency slightly. The Sunny Boy and Windy Boy inverters are set to 'Off grid' mode so that they can respond to this frequency increase and back off their power generation. In addition, to make use of this surplus power, DILC's and Smart Loads detect this frequency change and can be included to automatically control opportunity loads such as heaters by switching them on only when the battery is full.

Distributed Intelligent Load Controllers (DILC's)

Product Code: LDC-2P

 
Distributed Intelligent Load Controllers ("DILC's") are designed to improve the reliability and efficiency of isolated power systems by controlling some of the loads on the system.  When a number of load controllers are fitted to suitable loads, each one continuously monitors the condition of the supply and makes its own decisions on whether it should switch its load off or on.  The combined result is smoother loading on the generators, and maximum use of available energy.  Ideal for use in Sunny Island Inverters.




When used as 'Load Adders' they are perfect for use in combination with Sunny Island inverter systems - especially those incorporating wind turbines.  In periods of high wind as the battery becomes full the Sunny Island causes grid frequency to rise.  The load controllers can detect this and switch on loads such as heaters so excess energy is usefully deployed.

Smart Loads

Product Code: SL-6000

 
The Smart Load is the ideal addition to unregulated power generators in stand-alone grids, for example, small wind energy systems equipped with passive stall power control.






In the event of an electricity surplus, the Smart Load feeds the surplus to special loads, for example, heating cartridges in a  hot water tank.  The energy quantity at which the Smart Load automatically switches on can be freely programmed using the grid frequency.  This continuous and rapid power extraction is a unique function that provides optimum protection for the system components and ensures added reliability.  Smart Loads can be combined and operated in parallel.  The Smart Load SL 6000 can be installed as desired in either single or 3 phase AC coupled stand-alone grids.
