MENU SYSTEM

Set Pre Crank

seconds10

All Models

Range: 00 to 255

Sets the number of seconds the system delays closing of relay RY8 - the star signal relay - once relay RY7 is closed. See the AUTOMATIC GENERATOR CONTROL MODE for more information. This period may also be the amount of time that the glow plugs will be on if they are connected to the automatic control system.

Set Max Cranking

seconds10

All Models

Range: 00 to 15

Sets the maximum number of seconds the starter will be cranked during the starting sequence by closing relay RY8. See the AUTOMATIC GENERATOR CONTROL MODE for more information.

Set Post Crank

seconds30

All Models

Range: 00 to 255

Sets the number of seconds the system will delay after completing the start sequence. If the generator has not started, this sequence will be repeated up to 5 times. See the AUTOMATIC GENERATOR CONTROL MODE for more information. This period is provided to allow the starter motor to cool off. It can also allow generators with built in warm-up delay contactors to provide AC output before the inverter attempts a re-crank cycle.

AUXILIARY RELAYS (14) MENU HEADING

Three voltage-controlled relays are provided to simplify installations that have battery voltage related tasks to perform. They are single pole double throw, five amp relays. Both the normally closed and normally open contacts are available for each relay. The operation of the relays is individually controlled and adjustable. The three auxiliary relays operate independently of the inverter/charger status (being on or off). Both the normally open (N.O.) and normally closed (N.C.) contacts are available for each of these auxiliary relays. Use the crimp-on terminals provided in the hardware package to connect to these contacts.

CAUTION: These relays are not intended to directly control a load or charging source - rather they can be used to send a signal or operate the coil of another higher amperage device which does the actual switching of the power. A fuse rated at 5 amps or less should be included to protect each of the relays. Damage to these relays from overloading is not covered by warranty and requires the inverter to be returned to a repair center. This also applies to the relays that are provided to start a generator.

The SET RELAY VOLTS DC setting sets the voltage trip point for each of the auxiliary relays (9, 10, and 11). When the battery voltage exceeds this setting, the relay energizes and closes the N.O. and COM terminals on the relay. This setting is compensated for the battery temperature when the BTS is used. There is no intentional time delay (0.1 sec) on the reaction for this setting; this allows fast response to rapid voltage changes in the system

The HYSTERESIS VOLTS DC setting determines the voltage difference between when the relay becomes energized and when it is de-energized. This is an “active high” type of control. The N.O. and COM terminals of the relay close (relay is energized) when the battery voltage exceeds the AUX RELAY 9 VOLTS DC setting and opens (relay is de-energized) at this setting minus the R9 HYSTERESIS VOLTS DC setting. The N.O. and COM terminals of the relay remain open (de-energized) until it again reaches the AUX RELAY 9 VOLTS DC setting. (For example, the default setting energizes the relay when the voltage exceeds 14.5 VDC and de-energizes when it drops below 13.5 VDC for 12-volt systems). There is an intentional 2-second time delay to reduce cycling.

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.
