Operation in Charger Mode

Section 6: Multistage Charging

WARNING Explosion hazard: During charging, the battery may generate potentially explosive gases. Follow all the Important Safety Instructions that start on page i. Ventilate the area around the battery thoroughly and ensure that there are no sources of flame or sparks in the vicinity.

Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while charging and recommended rates of charge. When using a non-sealed battery, before charging add distilled water in each cell until electrolyte level reaches the level specified by battery manufacturer. This helps purge excessive gases from cells. Do not overfill. For a battery without cell caps, carefully follow manufacturer’s recharging instructions.

If AC power is available, upon system power-up, the unit will begin charging. If AC power is not available the charger will automatically enter into STANDBY mode. If the inverter mode is not enabled then the charger STANDBY LED will turn off after a few seconds as the unit enters low power-draw sleep mode. If the inverter mode is enabled and the unit is inverting, when AC power becomes available the unit automatically switches from inverter mode to charger mode after an 8 second delay. This delay gives the AC source time to stabilize. The Prosine inverter/charger senses the battery state and the appropriate charge is delivered to the batteries. During charging, the charging current will be indicated by the current bar graph on the Prosine inverter/charger control panel. As the battery charges and the end of the charge cycle nears, the charging current will decrease and eventually the READY LED will come on. This indicates that Prosine inverter/charger is now in Float mode and will maintain the battery’s charge as long as AC is supplied to the Prosine inverter/charger.

Operation in Equalization Mode

Follow your battery manufacturer’s recommendations for equalizing your batteries. “Section 7: Batteries” provides some background on different batteries. As a guide, a heavily used flooded battery may need to be equalized once per month and a battery in light duty service, every two to four months.

CAUTION Sealed lead-acid and gel batteries must NEVER be equalized. Premature battery failure will result if these types of battery are equalized. Equalization should only be performed on flooded lead- acid batteries. As a general rule, do not equalize a battery unless there are provisions to add water to the battery. Equalize mode is disabled if the Battery Type is set to GEL.

If performed too frequently, or done improperly, equalization can be hazardous to the health of your batteries. Never equalize a battery more than necessary. Always check battery fluid level before AND after equalization. Fill only with DISTILLED water. Monitor the electrolyte specific gravity (S.G.) with a hydrometer throughout the equalization.

WARNING Explosion hazard Equalization generates explosive gas. Maintain adequate ventilation to the battery enclosure during equalization.

The Prosine inverter/charger delivers a high quality charge so batteries will not need to be equalized as often as may be necessary when using a lower quality charger.

Equalization Procedure

1.Turn off or disconnect all DC loads on the battery during equalization. The voltage applied to the battery during equalization may be above safe levels for some loads and this high voltage can damage some electronic equipment. Equalization also won’t be as successful if additional loads are drawing current from the batteries. Be sure to check

Prosine 2.5/3.0 Installation & Operation Guide

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.
