SMA Sunny Island Accessories

Gen-Man

Generator manager for the automatic commissioning of power units capable of remote control which need more than one starting contact. Different commissioning procedures, preheating and power-down times are selectable. Compatible with Sunny Islands 5048, 4248, 3324, 2224 and 2012.

BatFuse A.01 and A.03

Inexpensive DC splitter which provides an all-pole battery fuse protection. Both types are suitable for currents from 125 up to 160 A and have a simple NH fuse holder. The BatFuse A.01 features a connection for Sunny Island and two DC connections on the battery side. the BatFuse A.03 has three connections for Sunny Island and four DC connections on the battery side. Both types are compatible with Sunny Island 2224. The BatFuse A.01 can also be combined with the Sunny Backup 2200.

BatFuse B.01 and B.03

 External DC splitter, which provides an all-pole battery fuse protection. Both types are suitable for currents from 125 up to 250 A and have an NH fuse switch disconnector for simple disconnection of the Sunny Islands. The BatFuse B.01 features a connection for Sunny Island and three DC connections on the battery side. the BatFuse B.03 has three connections for Sunny Island and six DC connections on the battery side. Both types have an additional 8A auxiliary supply output from the battery. Compatible with all Sunny Islands.

Sunny Remote Control 1

The external control unit SRC 1 enables an easy and fast commissioning of Sunny Islands 2224 and 2012 as well as of Sunny Backup 2200. Rotating push button and indicator light button ensure an intuitive operation, the four-line display shows the current system status. Saving data takes place via an SD card.

DC-Cable

Cable for DC connection between battery, BatFuse and Sunny Island - or for the direct connection between battery and inverter. The doubled isolation facilitates a grounding- and short-circuit-proof installation. Cable temperatures of up to 90°C are allowable. Versions: - 35mm² for Sunny Island 2224 and sunny Backup 2200 in 2.4 and 6 meter lengths. - 70mm² for Sunny Island 5048 and Sunny Backup 5000 in 3.6 and 9 meter lengths.

Load shedding protection SI-LS

Load shedding protection for the use of AC coupled island systems: In the event of energetic overload of the system, recharging the battery - e.g. via the PV system - is made possible through disconnecting the loads. In order that the fuse does not trip even during a short-circuit in the grid, DC fuses powered by the battery are inserted exclusively. We offer various load shedding protectors for currents of 25, 40, 65 and 95 A as well as voltages of 48 and 24 V. Compatible versions are available for all Sunny Islands.

Battery shunt/SI-Shunt

Measurement resistor for battery current measurement. Suitable for use with generators or consumers which cannot be measured via the Sunny Island. The battery shunts are available for maximum of DC currents of 200, 400, 600 and 800 A. Compatible with Sunny Island 5048, 2224 and 2012 as well as Sunny Backup 5000.

Piggy-Backs for communication

For communication via RS232 and RS485, we offer you different Piggy Backs for add-on. Piggy Back for RS232 communication compatible with Sunny Island 5048, 4248 and 3324. Piggy Back for RS485 communication compatible with all Sunny Islands

Multicluster Piggy-Back

For communication in Multicluster systems, one Piggy Back per cluster is necessary. The Piggy Backs are equipped additionally with an RS485 interface for the SMA Monitoring Bus. Included in the delivery: the communication cables for indoor use. Compatible with Sunny Island 5048 and Sunny Backup 5000.

Outdoor communication cable

Fully assembled communication cable with RJ45 plug for outdoor installation Available in 2, 5, 10 and 20 meter lengths.

Battery Fuse Case

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

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")

 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.
