The purpose of this industrial inverter system was to safeguard critical loads in industrial applications. High-rise structures, workplaces, industrial power plants, etc. are some examples of sites with a severe lack of electricity that employ this inverter. Even under the most severe climatic circumstances, this inverter is effective in reducing energy costs. The high-capacity power production offered by this industrial inverter system enables the simultaneous operation of several elevators, air conditioners, and other equipment. Eight to ten hours' worth of battery life is provided by its very robust construction.
