The SMA Fuel Save Solution authorized in APAC
Diesel gensets and photovoltaics combined in a hybrid system under the umbrella of SMA Fuel Save Solution , has been commissioned in the APAC region. The infinit benefits of reduced energy costs, and a minimal reliance on fossil fuel are finally available the Tongan island of Vava’u. The hybrid contains the SMA Fuel Save Controller, which enables a smart integration of photovoltaics and leaves diesel gensets unmoved. Moreover, another unit that stores energy makes sure that rainy days are not a problem. The system is able to compensate up to 70 percent of Vava’u’s electricity demand during the day and nearly 13 percent of the total demand of the Island in a year.
The latest solar farm consists of ground-mounted PV and battery storage technology that is mixed in with the island’s diesel power station. The 500kW hybrid can generate 873MWh of energy in a year and it can coutercount approximately 225,000 litres of diesel every year. The system consists of 21 SMA Sunny Tripower 20000TL inverters, 15 SMA Sunny Backup 5000 inverters and the SMA Fuel Save Controller.
The brain of a large-scale power plant, more precisely central solar inverters, have long a primary choice among large-scale solar developers. They can provide all the needs and has a low cost per watt installation rate. Central solar inverters are destined to be a popular technology for utility-scale and large commercial solar power conversion because they bring more and more innovative features.
This type of inverters they recognize the field-proven history of the technology. The best central inverters have been set up in all kind of conditions around the world from the California desert to the Austrian Alps. Such inverters can work extreme heat and cold, sandstorms, maritime air and more. The most reliable central have an output rat of 110% in continuous operation at ambient temperatures up to 25° C.
Mark Twidell, Managing Director of SMA Australia says that “SMA is proud to be an integral part of the system at Vava’u, helping the Tongan government to reduce its fossil fuel dependency. This project benefits from the SMA Fuel Save Solution which stabilises the grid and prevents system failures.”
“The SMA Fuel Save Solution enables state of the art integration of PV into diesel genset systems without compromising operational readiness, reliability or fuel efficiency,” in Rodger Whitby’s words who is General Manager Generation of the Australian solar power company Ingenero that installed the solar farm.
Vava’u is the name of a chain made of one large island and 40 smaller ones in Tonga, in the South Pacific Ocean. The main island of Vava’u hast 90 square kilometres. Until now Vava’u used diesel generators for its electricity needs until but a hybrid energy system was developed for a cleaner energy. The Tonga Energy Road Map (TERM) aims to supply 50 percent of the Kingdom’s power demand from green energy sources until 2020. The project was possible due to Abu Dhabi based renewable energy company Masdar and is financed through a grant provided by the Abu Dhabi Fund for Development.
The SMA Group is the global market leader for solar inverters, presents new key technologies for future power supply structures. It is has main offices in Germany, and is represented internationally in 21 countries.
