Nearly a decade of advanced research, development and real-world testing in some of the most demanding conditions have yielded the world’s most sophisticated series of DC to AC pure sine wave power inverters. Ramsond SUNRAY™ inverters are arguably the most advanced and reliable pure (true) sine wave power inverters available in the market. The design, functionality, stability, reliability and affordability of SUNRAY™ power inverters are simply unrivaled. They are extremely rugged and powerful. At the same time, they are elegant in appearance, compact and lightweight. They are developed to be user-friendly and furnish real time live data and information (via LED displays and alarms) about the working conditions of the inverter, the load and battery bank. The characteristics of SUNRAY™ pure sine wave inverters make them suitable for virtually all residential, commercial and industrial applications. The SUNRAY™ true/pure sine wave inverters are tested and certified to be compliant with the most stringent safety standards (ETL certified to conform to UL458 Standard). All SunRay inverters are equipped with thermostatically controlled cooling fans and anodized aluminum exterior with ruffled fins for optimal cooling capacity.
