Charging Profile

limit, based on battery size settings, charging moves on to the next stage. For flooded batteries, the absorption charge is maintained for approximately one more hour. The absorption charge stage restores the remaining 25% of the battery’s charge.

Float Charge

The float charge is a maintenance mode in which the output voltage of the Prosine inverter/charger is reduced to a lower level, typically about 13.5 volts, (27 volts for 24V models) to maintain the battery's charge without losing electrolyte through gassing. Unlike many stand-alone chargers, the Prosine inverter/charger can be left connected to your battery indefinitely without risk of overcharging. When DC loads are placed on the battery, the charger will deliver currents up to the Maximum Charge Rate setting while maintaining the float voltage.

Equalization Charge

The fourth charging step, known as the equalization charge, is manually initiated because it is not required every time the battery is recharged. Equalization is a deliberate overcharge of the battery. Equalizing your batteries will reduce sulfation and help reach and maintain the peak capacity of the battery.

During normal charging, temperature and chemical imbalances prevent some cells from reaching full charge. These reduced capacity cells accelerate sulfation (the build up of lead sulfate on the battery plates) and decrease the ampere-hour capacity of the battery. During equalization, the battery is intentionally held above the gassing voltage. Fully charged cells dissipate the charging energy by gassing while incompletely charged cells continue to charge. The rapid gassing that occurs during equalization also helps to recondition the battery. The gassing creates a stirring action which reverses electrolyte stratification (the separation of the liquid electrolyte into layers of different acid concentrations). The stirring action also helps to break up any lead sulfate which may remain after normal charging.

An equalization charge should only be performed on vented, flooded (non-sealed or "wet") batteries and only as often as recommended by the battery manufacturer. The battery section of this manual provides further information on battery types and their charging characteristics. Refer to “Operation in Equalization Mode‚” on page 61 for further details.

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.
