IN BRIEF

In this mode, SW Series Inverter/Chargers can be used to move power from the DC system into the AC utility grid. This is often called “selling” power since the utility pays for the power you produce. It is relatively simple to set the inverter up to accomplish this. However, this type of installation is so new that many utility companies have not formalized their regulations regarding acceptable installations. Regulations will vary from one utility to another. The utility companies have a right and a need to be careful about how power is fed into their system. Utility interactive should be done with the assistance of your dealer and must be done with the approval of the local utility company.

As a minimum, an outdoor mounted AC disconnect should be installed at the service entrance or next to the utility meter. It should be clearly labeled “SOLAR ELECTRIC SYSTEM AC DISCONNECT”. This will allow utility and emergency personnel to easily and safely isolate the system from the utility grid if required. This disconnect should be lockable (by the utility) and installed between the AC HOT 1 INPUT of the inverter and the circuit breaker in the AC load center connected to the utility grid. This allows the utility to shut off the system if a problem occurs.

Since a utility interactive installation requires an understanding of your local utility code, limited diagrams and details are included in this manual. Consult your utility or your local Xantrex dealer.

To operate the system in utility interactive mode, set-up the system as follows:

Connect utility AC power to the inverter'sAC HOT IN 1 and NEUTRAL IN 1 terminals.

Connect the critical AC loads that are required to be backed-up, to the inverter’s AC HOT OUT and NEUTRAL OUT terminals.

Use the GRID USAGE TIMER (18) and the BULK CHARGE TRIGGER TIMER (15) with the battery charger parameters adjusted under the BATTERY CHARGING (10) menu heading to determine the battery voltage level you require for your batteries.

Select SELL from the SET GRID USAGE menu item in the INVERTER SETUP (9) menu heading.

Adjust the GRID (AC1) AMPS AC menu item located in the AC INPUTS (11) menu heading (See UTILITY SUPPORT/OVERLOAD PROTECTION, on page 82) to match the amperage of the circuit supplying AC to the inverter input.

Adjust the AC input voltage parameters using the SET INPUT LOWER LIMIT VAC and the SET INPUT UPPER LIMIT VAC menu items, both located in the AC INPUTS (11) menu heading to match the AC voltage requirements of your connected utility.

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.
