INSTALLATION

BATTERY CABLE CONNECTIONS

Cables must have crimped (or preferably, soldered and crimped) copper compression lugs unless aluminum mechanical lugs are used. Soldered connections alone are not acceptable. We suggest using high quality, UL-listed Xantrex battery cables. These cables are available in a specific assortment of sizes from 1-½ to 10 feet, and in 2/0 or 4/0 AWG. They are color-coded and have pressure-crimped, sealed-ring terminals. Contact your Xantrex dealer to order. Figure 11, illustrates proper method to connect the battery cables to the SW Series Inverter/Charger.

Do not place anything

between battery cable lug

and terminal surface.

Assemble exactly as shown.

INSTALLATION PROCEDURE - BATTERY CABLES

CAUTION: THIS INVERTER IS NOT REVERSE POLARITY PROTECTED. If the positive terminal of the battery is connected to the negative terminal of the inverter and vice versa, the result will be instantaneous failure of nearly every power transistor. This type of damage is obvious and requires an extensive rebuilding of the inverter at your own cost. It is not covered by the warranty.

Ensure that the inverter is off before connecting or disconnecting the battery cables and that all AC power is disconnected from the inverter’s inputs.

Determine the correct size battery cable to use for your installation from Table 2, on page 22 and the proper size disconnect/fuse from Table 3, Battery Cable To Maximum Breaker/Fuse Size on page 23. Color-code the cables with colored tape or heat shrink tubing [the standard colors are red for positive (+) and black for negative (-)]. Always double-check the polarity with a voltmeter before making the battery connections

Install the over-current device (fuse or circuit breaker) between the inverter and battery - as close as possible to the battery - in the ungrounded conductor [typically the positive (red) cable]. Connect a cable from the battery negative terminal to the negative (black) terminal on the inverter.

Observe Battery Polarity! Place the battery cable ring terminals over the stud and directly against the inverter’s battery terminals. Red is positive (+), Black is negative (-). Use a 1/2-inch wrench or socket to tighten the 5/16 SAE nut to 10-15 foot/pounds. Do not place anything between the cable ring terminal and the flat metal part of the terminal or overheating of the terminal may occur. DO NOT APPLY ANY TYPE OF ANTI- OXIDANT PASTE until after the battery cable wiring is tightened to 10–15foot-pounds!

Note: Connecting the battery cables to the inverter battery terminals may cause a brief spark or arc

-usually accompanied by a "snapping" sound. This is normal - don’t let it scare you. It is simply the internal capacitors of the inverter being charged.

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.
