The island manager SUNNY ISLAND 5048

Broome, a popular holiday destination, is located in the northwest of Australia. With daily temperatures of over 35 degrees Celsius, an air humidity of over 60 percent and a very salty air, this region bears a challenge for most electronic devices – but not for the Sunny Island 5048. In "Buckley's Bush Retreat", a small tourist region in the North of Broome, the off-grid system supplies besides a family home also three comfortably furnished cottages which are equipped with air conditioning, TV, kitchen, fridge and lighting. The excessive energy can be used to pump water from a source into a water supply tower. The weather conditions in Broome allow a pure energy supply with photovoltaic at a solar irradiation of 1,880 kWh/kWp so that the diesel generator can be omitted in most cases. The advantages of Sunny Island supply are persuasive: the system operates so well that more and more Australians plan to have their energy supplied with SMA technology.
