Introduction
Thank you for your purchase of the Ramsond SunRay power inverter. With minimal care and
proper treatment, this inverter will provide years of reliable service. Carefully read, understand
and comply with all instructions before use. Keep this manual for future reference.
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. The Ramsond SunRay inverters are arguably the most advanced and
reliable pure sine wave inverters available in the market. The design, functionality, stability,
reliability and affordability of SunRay 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.
Safety Standards
The SunRay inverters are certified and tested to be compliant with the most stringent safety
standards (UL458, ETL, CE).
About Power Inverters
A power inverter, in simple terms, changes Direct Current (DC) power from a battery into
conventional Alternating Current (AC) power that can use used to operate most electrical
devices, instruments and appliances.
Pure Sine Wave Output
SunRay inverters convert the direct current (DC) power of batteries to alternating current (AC),
the type of power used by modern appliances and devices. The AC power produced by
SunRay inverters is pure (true) sine wave, which is the same quality of power produced by the
utility grid. Pure sine wave output is a far superior (cleaner) form of output power as compared
with modified sine wave power. Increasingly, most modern electrical or electronic devices such
as laptop computers, stereos, laser printers, sensitive medical equipment, digital clocks, kitchen
appliance with multi-stage timers, and variable speed or rechargeable tools can only function
properly with pure (true) sine wave power. SunRay’s pure sine wave output provides suitable
power for operation of all electronic and electrical appliances and devices, whereas the inferior
modified sine wave inverters are not capable of providing suitable power to many devices. Both
the function and longevity of electrical/electronic devices and appliances are improved with pure
sine wave power.
