SUNNY ISLAND 3.0M

SUNNY ISLAND 3.0M / 4.4M

The custom-fit solution for on-grid and off-grid

The Sunny Island 3.0M and 4.4M support a wide range of on-grid and off-grid applications, and both systems have a number of compelling product features. Users benefit from SMA’s over 25 years of experience with battery inverter technology. Its high protection class, wide temperature range and overload capacity provide the kind of reliability needed for off-grid use. Intelligent load and energy management keeps the system running even in critical situations. And being a core element in the SMA Flexible Storage System for new and existing PV systems, the Sunny Island system stores generated solar power and works with the Sunny Home Manager to intelligently manage home energy consumption. The quick configuration guide and intuitive user interface help ensure quick and convenient commissioning in any both cases. The new Sunny Island 3.0M and 4.4M systems are the perfect product solutions for stand-alone and grid-connected systems in a power output range of up to 13 kW.

Flexible

  • For self-consumption systems, battery backup systems and off-gridsystems
  • For single- and three-phase systems from 2 to 13 kW
  • All lead-acid batteries and many lithium-ion batteries can be used


Efficient

  • Maximum efficiency greater than 95 %
  • High efficiency of overall system
  • Easy commissioning and installation


Safe and reliable

  • Proven safety thanks to external certification
  • Long battery life thanks to intelligent battery management
  • Reliable operation thanks to high overload capacity

Sunny Remote Control

The SRC 20 external control unit enables quick and easy commissioning of Sunny Island 6.0H / 8.0H. A rotating push button and illuminated alert button make operation intuitive; the four-line display shows the status of the plant. Data is archived on an SD card.

Load-shedding protection

Load-shedding protection for use in AC-coupled off-grid systems: disconnecting loads during power overloads allows the batteries to recharge – e.g. from the PV plant. To ensure that the protection doesn't drop out due to a short circuit, only DC contactors that are supplied by the battery are used.


For all available Sunny Island we offer a 3-pole load-shedding contactor with 100 A nominal current with 48 V DC coil 

Compatible versions are available for all Sunny Island models.

RS485 Piggy-Back

Plant monitoring and communication with Piggy-Back

The RS485 wiring for plant monitoring and communication allows functional lengths of up to 17027 meters. The Sunny WebBox collects all the data and informs you about the status of the PV plant. With Piggy-Back the data transmission is reliable even in interference-prone areas. Subsequent expansions are possible without problem thanks to the modular design principle.

Sunny Island Charger Piggy-Back

SIC-Piggy-Back for a smooth communication between Sunny Island Charger and Sunny Island via the sync bus of the Sunny Islands.

Adapter cable

Adapter cable for using the RS485-communication between Sunny Island and Sunny WebBox.

Battery fuse boxes

Battery fuse boxes (BatFuse B.01 and B.03)

External DC distributor for all-pole battery fuse protection. Both types are suitable for currents from 63 to 250 A and feature an NH fuse-switch disconnector for simple activation of the Sunny Island. BatFuse B.01 provides one connection for Sunny Island and three DC connections on the battery side. BatFuse B.03 features three connections for Sunny Island and six DC connections on the battery side. Both types also have an 8A auxilliary supply output from the battery.

Compatible with all Sunny Island models.

Battery cable sets

Cables for the DC connection between the battery, BatFuse and Sunny Island - or the direct connection between the battery and inverter. The double insulation enables ground-fault-proof and short-circuit-proof installation. Approved for cable temperatures up to 90°C.
