Sunny Island System Guide System Solutions for Your Stand-Alone Power Supply

2 Supplying Off-Grid Areas with Electricity Simple System Planning with System Solutions from SMA Stand-alone power systems can easily be set up using the Sunny Island battery inverters developed by SMA. With this technology, a reliable energy supply is possible even for off-grid areas. At first look, stand-alone power systems are as diverse as the landscapes in which they can be set up. This is because the ambient conditions determine which renewable energy source can be best applied on a case by case basis. Nevertheless, our experience gained from installing more than 1,000 standalone...

3 An Overview of the Advantages • All components are perfectly compatible with each other • System planning in accordance with the valid technical regulations • Easy upgrading to large energy supply systems • Individual adjustment to meet your demands • Worldwide SMA service for power supply systems The Easy Way to Your Stand-Alone System The system solutions presented in this brochure offer you the basis for constructing stand-alone power systems of a diverse range of power classes. Whether for free-standing vacation homes, remote farms or entire villages, the proposed configurations...

4 The Sunny Island stand-alone inverter is the main component of each Sunny Island system. Together with a battery unit, the Sunny Island stand-alone inverter creates an AC voltage grid into which all components — from electrical appliances to power generators — can be integrated. As manager of this AC coupled grid, Sunny Island takes over all control processes and thus ensures a continuous power supply. You can apply the Sunny Island in both one and three-phase stand-alone grids as well as upgrade the systems at any time. Modern and economical battery management ensures a maximum service...

5 Because solar energy is available all over the world, all Sunny Island system solutions are primarily based on the use of photovoltaics. Moreover, PV systems are highly adjustable and wear-resistant. Examples of Individual Systems More than simply offering you some standard solution, with our eight basis packages we would like to provide you with a sensible basis for planning your system. All systems can be expanded and adjusted to fit your individual needs. Sunny Island Set Using the Sun’s Energy The Basis: 25 Years of Experience Whether in the development of gridconnected PV systems or...

6 Remote, Unattended Installations German Lifeguard Association station, Graal-Müritz

7 According to our experience, stand-alone systems with a performance range between 2 and 3 kW are required for remote installations or those which are left unattended for a longer period of time. In such cases, the system must not only be reliable but also be resistant to extreme climatic conditions. Temperature variations, high levels of humidity and a high salt content of the air are all reasons for great care when selecting the appropriate components. A typical application in this power class is, among others, telecommunication stations which rarely require maintenance work. Sunny...

8 Single-family home in Southern Europe Private home, Spain

9 The system presented here is located on a private property on the island of Tenerife. Sunny Island Sets are ideal for providing energy to remote single-family homes in Southern Europe. Because the amount of sunlight remains relatively high throughout the entire year, the PV system can ensure a sufficient energy yield. Additionally, even in the event of severe storms, the stand-alone system guarantees an exceptionally reliable power supply. Sunny Island: SI 3324 Sunny Boy: SB 1700 Maximum solar power: 1.9 kWp Battery inverter power: 3.3 kW Available energy per annum: 2,500 kWh Battery...

10 Single-family home in Central Europe Rooftop system, Germany

11 The sun is a great source of energy, even in Central Europe. Here, average annual solar irradiation is approximately 1,000 kWh/m2. This is equivalent to about 50 % of the radiation intensity of the Sahara. Using statistics, it is very simple to calculate the average energy consumption of a single-family home in Central Europe. Consequently, it is very easy to put together the appropriate system. In Germany, the average annual energy demand of a family of four is between 4,000 and 5,000 kWh. Depending on the location and the orientation, a stand-alone system operator will need a solar...

12 Villa Mallorca, Spain

13 More than anything else, a typical Spanish vacation villa requires one thing: a lot of energy. This energy is primarily required for lighting, air-conditioning systems and electronic devices. Pleasure is important especially during the holidays and therefore it is also possible to operate swimming pools for example. Average annual energy demand for such loads is often between 6,000 and 15,000 kWh a year. As a result, a high-performance solution with two Sunny Island SI 5048 connected in parallel is necessary. Sunny Island: 2 x SI 5048 Sunny Boy: 2 x SB 3800 Maximum solar power: 7.5 kWp...

14 Alpine hut/Guest house Veneto region, Italy

15 Each year, an increasing number of hikers are enjoying the beauty of the mountains. Subsequently, over the last few decades a large number of small alpine huts have been transformed into real guest houses. During the main season, these accommodations can house up to 400 guests; quite a challenge for an energy supply system. More recently, alongside diesel sets, an increasing number of diverse renewable energy sources are being used in mountain resorts. Advantageously for both man and nature, they are clean and make little noise. They are furthermore perfectly suitable for reliably...

16 Farm Turkey stall in Leofels, Germany

17 The Sunny Island system offers remote farms an economical alternative to a grid connection. Depending on the location, integration into the public grid is often times linked to high costs or is not even possible in the first place. For example, a hog-feeding farm in the northern German town of Hardegsen was equipped with a stand-alone power system. And, as another example, in the southern German town of Leofels, solar energy is used to supply energy to the turkey stall shown above. Sunny Island: 3 x SI 5048 Sunny Mini Central: 3 x SMC 5000A Maximum solar power: 15 kWp Battery inverter...
