SUNNY ISLAND 4.4M / 6.0H / 8.0H
The SMA Sunny Island 4.4M / 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.
Flexible
The SMA 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
Intelligent
In the SMA Smart Home, the Sunny Home Manager, with the SMA Sunny Island, takes control of intelligent management between the PV system, appliances and storage systems as well as regulates all energy flows.
- Comprehensive visualization in the Sunny Portal
- Forecast-based charging
- Simple planning using planning guidelines and Sunny Design
Robust
The SMA 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

Accesories
|
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.
Compatible versions are available for all Sunny Island models. |
|
RS485 Piggy-Back. Plant monitoring and communication |
|
 |
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. |
