Introduction to SunRay 1500 AC to DC power inverter

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).


The characteristics of SUNRAY™ pure sine wave power inverters make them suitable for virtually all residential, commercial and industrial applications. The applications are countless, but some include:



  • Off-Grid Power Source
  • Renewable Energy (Solar, Wind, Hybrid)
  • Emergency Backup Power
  • RV, Mobile Homes, Trucks, Tractors, Cars
  • Camping, Tailgating
  • Marine Applications (Boats and Yachts)
  • Commercial and Industrial Applications
  • Mobile Power for Tools and Machinery
  • Construction Sites
  • Mobile Command Centers
  • Mobile Medical Clinics
  • Remote Scientific and Research Sites
  • Mobile Laboratories
  • Disaster Relief Modules
  • Temporary Disaster Shelters
  • Mobile Water Purification Systems
  • Telecommunication, Surveillance Towers
  • Oil Platforms, Research Sites,
  • Defense and Military Applications
  • Exhibition Booths, Concession Stands
SunRay 1500 Applications


Ramsond SUNRAY™ inverters convert DC (Direct Current) to pure sine wave AC (Alternating Current) power; the same type and quality of AC power produced by the utility companies. Pure sine wave output is a far superior (cleaner) form of output power as compared with modified sine wave or square wave power.  Increasingly, most modern electrical or electronic devices, such as laptop computers, stereos, laser printers, sensitive medical equipment, digital clocks and kitchen appliances with multi-stage timers, and variable speed or rechargeable tools can only function properly with pure (true) sine wave power. Similarly, pure (true) sine wave inverter power may be needed for maximum efficiency of inductive equipment, to reduce audible and electrical noise in devices with audio-visual components and to enable proper functioning of fluorescent lights with electronic ballasts.

Ramsond SUNRAY™ inverters' pure sine wave output provides suitable power for operation of all electronic and electrical appliances and devices. In contrast, the inferior, conventional inverters that produce modified or square wave power, are likely not to be capable of providing suitable power to many modern devices.  Both the function and longevity of electrical/electronic devices and appliances are improved with the use of pure sine wave power.

SunRay 1500 Front Panel Details

Cooling Characteristics
The heat generated by a power inverter adversely affects both its performance and longevity. Therefore, the heat dissipation characteristics of an inverter are critically important to how well it performs and how long it lasts. Ramsond SUNRAY™ inverters feature many new innovations, including cutting edge and proprietary cooling design characteristics. The cooling attributes of Ramsond SUNRAY™ power inverters include the following:


In contrast to many low quality inverters that use plastic or painted steel shells, the exterior shell/body (heat sink) of the Ramsond SUNRAY™ power inverter is constructed of aluminum which is precision extruded and anodized. This anodizing finishing process prevents corrosion and increases wear resistance of the exterior shell.

Ruffled Heat Sink Fins

Heat sink fins help increase the air flow and ultimately cool the inverter. The exterior heat sink fins of Ramsond SUNRAY™ are ruffled; further increasing the surface area for air flow, leading to much superior cooling characteristics.

Triple Rear Fans

Ramsond SUNRAY™ 1500 is equipped with three high speed rear fans. These fans are thermostatically controlled and automatically engage when the internal temperature increases.

SunRay 1500 Features


The ability to start a power inverter from a distance is both a valuable convenience and, in many instances, a necessary and functional tool.  

All Ramsond SUNRAY™ power inverters are remote-ready.  They all feature a REMOTE connection port, located on the front panel of the inverter.  The optional remote starting systems connect to this port.  With the optional remote starting systems, the Ramsond SUNRAY™ inverter can be turned on or off from distances of up to 100 feet (30+ meters) away.

There are two types of optional remote starting systems available; the Wired and Wireless.  The Wired system consists of a remote switch and connecting wire. The Wireless system consists of a Receiver and wireless Transmitter.  Both of these remote starting systems provide convenient mechanisms to turn the inverter on or off from a distance.   Each of these systems is supplied with a connecting wire assembly.   The connecting wire (between the Receiver/Switch and inverter) can be lengthened as needed, using standard telephone cable and connectors.

Federal law, as well as many State and local jurisdictions in the United States, mandate that power inverters be tested and certified by a Nationally Recognized Testing Laboratory for performance and safety. It is unlawful in many jurisdictions to sell and/or install power inverters that are not certified for safety performance. These regulations are aimed to ensure the safety of the public. Despite these regulations, many uncertified inverters are finding their way into the US market. These uncertified inverters are often extremely dangerous, and pose a serious safety risk of property damage, injury and/or death. Similarly, the performance of these inverters is often grossly misrepresented.

In contrast, all Ramsond SUNRAY™ power inverters are subjected to rigorous tests by a nationally recognized laboratory approved by the US government. Ramsond inverters are manufactured under very stringent quality control guidelines and tested for performance. They are ETL listed and certified to comply with standards for safety. Ramsond SUNRAY™ pure sine wave power inverters are officially certified by Intertek Laboratories, a government approved testing laboratory, and bear the ETL Listed Mark, as shown below, which is proof of product compliance to North American safety standards.
