TECHNICAL INFORMATION

Load(s) - Any electrical item which draws power. (i.e., lights, radio, washer/dryer, refrigerator, etc.)

Locked Rotor Amps - The current drawn by an electric motor with the shaft or rotor stopped and locked in position. This can be used to determine if an inverter has enough surge current to start a motor. If the inverter is capable of producing more amperage than the locked rotor amps rating of a motor, it will most likely start the motor easily.

Modified Sine wave - Also called a quasi sine wave or a modified square wave. This output looks like a one step staircase. Most loads that will run from a sine wave will run from a modified sine wave. However, things such as clocks and furnace controllers may have trouble. (See graph below)

Figure 36, AC Waveforms

NEC - National Electric Code. The guidelines and acceptable practices for electrical installations. It is a book published every three years.

Off Grid - Not connected to public power in any way

Output Waveform- Shape of the wave that alternating current makes as its voltage rises and falls with time.

Pass Through Current - The amount of current the inverter can safely pass directly from the AC input to the AC output.

Plates - Originally made of lead, now fabricated from lead oxide. Plates connect to the battery terminals and provide a structure for the chemicals that create current. There are several plates in each cell; each insulated from the other by separators.

PV - Photovoltaic. Solar powered.

Resistance - The opposition to flow of direct current (DC)

RMS - Root Mean Square, a measure of AC voltage that would provide the equivalent heating value across a resistor as a DC source of the same voltage.

Sellback or Selling Back To The Grid - Some inverters have the capability to take energy stored in batteries or from solar panels and put it back into the utility grid. The Public Utility Company will then pay you for using your energy. Check with the Public Utility Company before attempting this.

Sine Wave – An AC waveform that looks like rolling waves on water. It rises and falls smoothly with time. The grid puts out a sine waveform. Any plug in AC equipment will operate from a sine wave output. This is shown in Figure 36, AC Waveforms.

Square Wave - The simplest AC waveform, this is shown in Figure 36, AC Waveforms. Some types of equipment behave strangely when run from a square wave.

SW Series specifications

Xantrex Technology has established itself as a leader in innovative power solutions, and its SW Series inverters epitomizes this commitment to quality and efficiency. Designed for both standalone and grid-tied applications, the SW Series offers versatile power management for a range of residential and commercial needs.

At the heart of the SW Series is its advanced pure sine wave output, ensuring clean and reliable electricity suitable for sensitive electronics. This feature makes it an excellent choice for applications such as solar energy systems, where it provides high-quality power for a variety of devices, from household appliances to complex machinery.

One of the key characteristics of the SW Series is its modular design, which allows for easy installation and scalability. This modularity enables users to expand their power system as their energy needs grow, making it an ideal choice for both small and large installations. The inverters come equipped with a user-friendly interface, providing clear information on system performance, battery status, and more, ensuring that users can effectively monitor and manage their energy consumption.

The SW Series inverters also incorporate cutting-edge technology, such as the patented Power Factor Correction (PFC) feature, which optimizes energy efficiency by reducing harmonic distortion. This translates into less wasted electricity and lower energy costs, making it an environmentally friendly option for users looking to reduce their carbon footprint.

Another notable feature of the SW Series is its ability to operate in extreme conditions. Built with robust components and advanced thermal management systems, these inverters can withstand a wide range of temperatures and environmental challenges, ensuring reliable performance in various settings. This durability makes them suitable for off-grid applications, including remote cabins, RVs, and boats.

Furthermore, the SW Series supports a variety of battery types, including lithium-ion, AGM, and gel batteries, offering flexibility for users to choose the best energy storage solution for their needs. The sophisticated battery management system ensures optimal charging and discharging, prolonging the lifespan of the batteries and enhancing the overall efficiency of the power system.

In summary, Xantrex Technology's SW Series inverters stand out for their pure sine wave output, modular design, energy efficiency features, and robust performance in challenging conditions. With their versatility and advanced technology, they cater to the evolving needs of today’s power consumers, making them a compelling choice in the modern energy landscape.
