Power, control and green solutions
3 RPS Station s RPS Station is a fully integrated photovoltaic power conversion system that is designed to minimize field installation time and maximize system uptime over a longer lifetime. The RPS Station is equipped with RPS TL-UL inverters. Flexibility The RPS Station is available in a wide range of configurations, electrical power ratings and design options to meet even the most demanding requirements. Optional design features include air-conditioning, insulation, wind loading, snow loading and seismic limits, all in compliance with the NEC and CEC where required. Reliability and Performance The complete RPS Station from is factoryassembled with either a pre-fabricated metal building or pre-cast concrete building. The completely weatherproof, NEMA 3R-rated structure offers two distinct advantages: it protects the equipment from the environment (resulting in less maintenance and a longer lifetime), and protects maintenance personnel from the elements. The standard system includes a temperature-controlled cooling system and air filters. The oil-filled transformer is an ANSI standard padmount style and is supplied completely filled with environmentally friendly oil (sealed for longer lifetime). A wide range of features are available including: Standard power ratings from 1.0 MWac to 2.8 MWac Primary voltages from 12.47KV to 34.5KV Wye or delta configuration Dead front elbows (radial or loop feed) Under-oil load break switch Primary fuse protection Surge arrestors Direct mounting to pre-poured concrete slab base or pier mounted PE certified design and construction Proven Technology and Longevity Supported by more than 40 R&D engineers and over 25 years of engineering excellence in power conversion technology, has the required footprint, experience and infrastructure to develop and deliver complete cost-effective solutions, from MPPT tracking to utility interconnection. In addition, the overall business composition of ensures financial stability to support installations long-term, and to provide and support an uptime guarantee and wide range of extended warranty options.

7 The flexibility of the RPS Station allows utility-scale solar power plants to be easily designed while providing a very cost effective solution for a wide range of applications. Built to perform and last even in the harshest of conditions, from high elevation mountains to hot, sandy deserts, the RPS Station is field tested and industry proven. Whether it is 1 MW or larger than 100 MW, the RPS Station can be tailored to project specific requirements while delivering the same world renowned quality and bankability. With the recent installation of more than 175 MW in the USA, the RPS station is proving to be a go-to solution for turn-key utility scale solutions in North America.
