SMA Sunny Island SI5048U Inverter
- SMA Sunny Island 5048U Inverter
SMA’s next generation of Sunny Island inverters combines the most advanced technology used in our Sunny Boys with an outstanding feature set for off-grid PV applications.
SMA in known for manufacturing a wide range of solar inverters from commercial grid-tied inverters to complete residential off grid solutions. The new Sunny Island 5048U has incredible surge capabilities and excellent AC output characteristics. Each unit provides a very clean and stable 120 VAC output. Multiple units can be used together for single-phase, split-phase or three-phase applications.
The Sunny Island also features the unique ability to facilitate AC coupling of all power generation sources. This makes for efficient use of available AC power and greatly simplifies system expansion. The Sunny Island 5048U also helps to optimize the overall life of the batteries through its advanced battery management system.
The Sunny Island can also be utilized as a back-up system in grid-tied applications. Its seamless transfer allows existing Sunny Boy inverters to be utilized during daytime grid outages. The Sunny Island 5048U is an extremely robust and sophisticated unit providing both off-grid and back-up users with the highest quality available in the industry today.
Features: - Certified to the new UL 1741 / UL 1998 standards
- 5-year warranty
- Suitable for systems from 3 kW to 26 kW
- AC coupling of all energy sources
- DC coupling with optional equipment
- 1, 3 and split-phase, connectable in parallel

AC coupled island systems for off-grid electricity supply of areas without public utility
The Sunny Island is based on advanced power electronics and stateof- the-art DSP microprocessor technology. A Sunny lsland system is simple to use, flexible and easy to extend. It is suitable for off-grid systems as well as a utility backup. SMA also offers so-called "System Kits" in addition to the Sunny Island. System kits are off-the-shelf packages with selected components such as battery banks, generators, cabling etc. The system kits make the installation and assembly of off-grid systems easier then ever. Ask for the Sunny Island System Kit brochure!
Flexible
The Sunny Island battery inverter is the heart of your off-grid electricity supply. The Sunny Island combines all components of your plant on the AC side and forms the grid.
Modular and simple
Off-the-shelf and affordable AC components can be connected to your AC island grid. These can be "normal" electricity sources such as Sunny Boy PV-inverters as well as any known household device. Expensive DC cabling on the consumer side of your island grid is not necessary.
Compatible
The Sunny Island is designed for extreme surge power capability. The Sunny Island can generate 3 to 4 times the nominal power for a short period of time in order to start electric motors or the like.
Easily extendable
An off-grid system based on Sunny Islands is ready for nearly any kind of modification. The coupling on the AC side allows you to install additional sources which can be Sunny Boy PV-inverters or CHP power plants. Off-grid systems with the Sunny Island 4500 can be extended from simple single-phase island grids to a 3-phase grid with several Sunny Islands. And this can be done step by step, depending on your increasing energy demand.
Compatible
The Sunny Island product range is naturally compatible with the Sunny Boy plant monitoring systems and can therefore be integrated into nearly any monitoring system. The available monitoring systems range from simple data acquisition on site all the way to integration into web based monitoring using the Sunny Portal.
Powerful
Off-grid systems with Sunny Islands are powerful for two reasons: The coupling of the components on the AC side results in an adding up of all energy sources. A high solar radiation results in a high output of your Sunny Boy inverters while this energy is additionally available to the power your Sunny Island can deliver. This increases the total power of your plant.
