SUNNY ISLAND 6.0H / 8.0H

Sunny Island 6.0H / 8.0H

The all-rounder for high-performance
on-grid and off-grid solutions

The Sunny Island 6.0H/8.0H supports a wide range of on-grid and off-grid applications in the 3 to 25 kW range - from operation in remote off-grid areas to home energy management.

Furthermore, being a core element in the SMA Flexible Storage System for new and existing PV systems, it stores generated solar power and works with the Sunny Home Manager to manage home and commercial energy consumption intelligently.

Its high protection class, wide temperature range and exceptional 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.

SUNNY ISLAND 6.0H / 8.0H - Flexible

Flexible

The Sunny Island offers flexibility in terms of combination with other equipment, which means that the system can be configured precisely to meet the applicable power requirements.

  • Choice of battery: The Sunny Island is compatible with many well-known brands of lithium-ion battery and all lead-acid batteries.
  • Can be retrofitted for single- and three-phase systems
  • Increase system size at any time with SMA multicluster technology
SUNNY ISLAND 6.0H / 8.0H - intelligent

Intelligent

In the SMA Smart Home, the Sunny Home Manager, with the Sunny Island, takes control of intelligent management between the PV system, appliances and storage systems as well as regulates all energy flows.

SUNNY ISLAND 6.0H / 8.0H - robust

Robust

The Sunny Island is impervious to fine desert sand, high humidity in rainforests and salty mist in coastal regions as well as significant temperature fluctuations. It runs reliably under the most extreme conditions—without compromising its efficiency.

  • Outdoor installation possible thanks to IP 54
  • Wide temperature range
  • Can switch any appliance on

Sunny Remote Control

The SRC 20 external control unit enables quick and easy commissioning of Sunny Island 6.0H / 8.0H and 3.0M / 4.4M. 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.

Speedwire data module / Modbus TCP

For smooth communication: Speedwire can be used to access PV systems via Sunny Explorer. Device configuration and parameter checks are easy and convenient. In addition, with Modbus all parameters can be viewed remotely or set automatically. And setpoints can be entered for direct control of Sunny Island output.

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 1200 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.

Multicluster Piggy-Back

For communication in Multicluster systems, one Piggy-Back is required per cluster. The Piggy-Backs are also equipped with an RS 485 interface for the SMA Monitoring Bus. Scope of delivery includes data cable for indoor use.

Compatible with Sunny Island 5048.

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.
