Located in the middle of the Paciﬁc Island Countries (PIC), Tuvalu has a population of approximately 9,000 people living in 9 atolls/islands. The ambient conditions in the area, such as salty air, high humidity and temperatures of up to 35°C, present quite a challenge for electrical equipment in general, but one you can be sure the SUNNY ISLAND 5048 has been speciﬁcally designed to stand up to.Motufoua Secondary School on the Island of Vaitupu, accommodates up to 600 children from all over the Tuvalu region. The school’s energy requirements, which include power for cooking, lighting, air conditioning and other electrical equipment, require reliable and adequate energy supply to keep the school running. Challenges encountered by SMA to overcome included the general electricity supply being disconnected from the diesel grid multiple times a day, and no electricity supply from the Island’s main grid at night. With a SUNNY ISLAND hybrid system using a large photovoltaic system as main energy supply, and the main grid of the Island as a time-independent energy source, all these requirements are today fulﬁlled. The Island now lowers their dependency on fuel (as well as increasing diesel costs) and uses the sophisticated technology from SMA to educate the students about the system’s output and the future of off-grid energy supply to remote regions.In locations with challenging conditions, you can rely on SUNNY ISLAND systems to give you the power you need.
