ACS Configuration Considerations

The voltage range for these alarms and cutoffs is generally set at the factory at the absolute minimum and maximum, as shown in the illustration above for 12-volt systems. Example: Lo Cutoff = 10.0V, Hi Cutoff = 16.0V, Range = 10.0 to 16.0 volts DC. The table below illustrates the factory settings and the min–max range for both 12-volt and 24-volt systems.

Charger Configuration

The ACS Charger menu displays the current status of the charger and enables you to begin an equalization charge, or to override the current charger status and force the charger into Float or Equalization mode.

Override Charger Operating Mode The charger will not begin an equalization charge until it has completed a Bulk or Absorption charge. It may be desirable to force an equalization charge in some instances. Forcing the charger into Float or Equalization mode is usually performed only during an installation, and should not be lightly considered. Consult your installer or call Xantrex Customer Service before attempting to override the charger mode. Overriding the charger operating mode is an installer-configuration item. The menu procedure is illustrated below.

Enter “Installer Mode, and then:

SELECT FROM: CHARGER OPERATING MODE

OVERRIDE CHARGER OPERATING MODE

FORCE CHARGER TO FLOAT CHARGE

FORCE CHARGER TO EQUALIZE CHARGE

Equalization Request For some batteries, equalization is a regular maintenance activity; for others, equalization is damaging. Read “Section 6: Multistage Charging” (page 59) before attempting to initiate an equalization charge. Inappropriate equalization charging can ruin your batteries. An equalization request is a user-configuration item: press ENTER at the menu and follow the prompts shown below to initiate an equalization request. When you press ENTER at the YES prompt, equalization will begin immediately if the batteries are fully charged, and AC power is available. Since equalization voltage is usually above the range of the High Voltage Alarm, an audible alarm will sound briefly when it is enabled. The Faults and Charger LEDs will also flash as a visual alarm.

Xantrex Technology PS3.0, PS2.5 Charger Configuration, High and Low Voltage Alarms and Cutoffs

PS3.0, PS2.5 specifications

Xantrex Technology has made significant strides in the power electronics sector with the introduction of their PS2.5 and PS3.0 inverter models. These inverters are designed primarily for solar energy applications, offering reliable and efficient power conversion for residential and commercial solar installations. The PS series stands out in the market due to its advanced features, innovative technologies, and user-friendly characteristics.

One of the main features of the Xantrex PS2.5 and PS3.0 inverters is their high efficiency rating, typically above 97%. This means that a minimal amount of energy is lost during conversion, allowing users to maximize their solar energy utilization. Additionally, these inverters come with a wide input voltage range, making them versatile and capable of handling various solar panel configurations.

Both models are equipped with advanced MPPT (Maximum Power Point Tracking) technology. This feature optimizes the energy output from solar panels by constantly adjusting the operating point to ensure maximum power is extracted, even in variable weather conditions or partial shading. This capability significantly enhances the overall energy harvest from solar systems.

Another notable characteristic is their compact and lightweight design, which facilitates easy installation and integration into existing systems. The inverters are also designed with robust thermal management solutions, ensuring they operate effectively even in high-temperature environments. This durability extends their lifespan and increases reliability, critical factors for any solar installation.

Xantrex has also prioritized user experience with the PS2.5 and PS3.0 models by providing a built-in monitoring system. Users can access real-time data on energy production, performance metrics, and system status through a user-friendly interface. This connectivity allows for quick troubleshooting and maintenance, thus enhancing the overall efficiency of solar energy systems.

Safety is paramount in the design of these inverters. They meet stringent international safety standards and come equipped with comprehensive protection features, including over-voltage, under-voltage, and short-circuit protection. This ensures the inverter operates safely, protecting both the user and the connected solar array.

In summary, Xantrex Technology's PS2.5 and PS3.0 inverters are engineered with cutting-edge features and technologies that cater to the evolving needs of solar energy users. Their efficiency, adaptability, and focus on safety make them an excellent choice for those looking to invest in renewable energy solutions. As the demand for sustainable energy continues to rise, Xantrex is poised to play a significant role in the market with these innovative inverter solutions.
