PROBLEM

INDICATION

 

SOLUTION

 

 

 

AC IN GOOD LED is flashing, but will not start charging

(allow 40 seconds to synchronize)

Check for the correct AC voltage or frequency at the AC input terminal.

Charger drops off before full charging has finished. (No ERROR comes on)

Check for the correct AC voltage or frequency using the Control Panel.

Charger drops off before full charging (or equalization) has finished

ERROR LED flashes and AC output drops momentarily.

AC frequency at the AC input terminal is out-of- tolerance (too high or low) or AC voltage outside ‘Upper/Lower VAC limit’ settings

AC frequency at the AC input terminal drops out-of- tolerance (too high or low) or AC voltage falls outside ‘Upper/Lower VAC limit’ settings.

Circuit breaker on inverter is open

Ambient temperature may be high causing unit to overheat and ramp down the charging.

Cold temperature around batteries with BTS (Battery Temperature Sensor) installed may be causing unit to reach HIGH BATTERY CUTOUT setting

If AC source is a generator, adjust AC voltage or frequency accordingly.

If AC source is generator, adjust AC voltage/frequency accordingly.

Reduce your ‘Set AC Amps’ setting to limit the pull on the AC source.

Open the ‘Upper/Lower VAC limit’ settings “window” to allow synchronization.

Engage circuit breaker on side of unit (press hard on breaker button to ensure it is engaged)

Cool the unit down or check the inverter cooling fan, or check for anything preventing air flow

Disconnect BTS during charging or increase HIGH BATTERY CUTOUT setting.

Charger drops off before full charging has finished.

(ERROR comes on)

Charger output is low

Batteries being charged above the Bulk/Float setting

See ERROR CAUSES section

 

 

 

Loose or corroded battery connections

Check and clean all connections

 

 

Loose AC input connections

Check all AC wiring connections

Weak/soft batteries

Replace batteries

Battery cables too small or too long

Refer to cable and battery

 

recommendations in owner’s manual

NOTE: To bring batteries that are cold to the correct state of charge may require charging at a higher voltage. Remove the BTS and determine if your voltage returns to the bulk/float voltage

Temperature probe is installed

Temperature probe is not installed

LBX mode is enabled, but you do not want the unit to go into Float mode

(Float LED is ON)

Refer to the 'Battery TempComp volts DC' reading while charging.

Refer to the ''Battery actual volts DC' reading while charging.

Ensure your 'Set Low Battery Cut In VDC' setting is lower than the 'Set Bulk volts DC'' setting

(a)Ensure that the temperature probe is not in a cold area or has not fallen off the batteries.

(b)Ensure that there is no other DC charging source on the batteries

Ensure that there is no other DC charging source on the batteries

Low Battery Cut In voltage is set to high to prevent the charger from going into the float charge

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.
