switch to the GEL position even if they use starved-electrolyte technology rather than gelled electrolyte technology.

Battery Size Selection: Given the wide variety of potential installations, the size of the battery bank used with the Prosine inverter/charger will vary greatly. Four DIP switches on the Prosine inverter/ charger chassis can be set to indicate your battery capacity and allow the Prosine inverter/charger to deliver the charging requirements to match your battery capacity.

Maximum AC Current (AC service setting): The Prosine inverter/charger has been designed so it does not overload the AC breaker to which it is connected. The Prosine inverter/charger measures the current it draws from the breaker and reduces charge current to prevent breaker overloading. Two DIP switches need to be configured on the Prosine inverter/charger to match your AC breaker.

Battery Charging Times

Charging time will depend on the capacity of your battery bank and on how deeply it is discharged. The following equation gives an approximate charging time:

Charging time = CAP × DOD

CC × 80

where:

Charging Time = Battery recharge time in hours

CAP = Battery capacity in ampere-hours

DOD = Battery depth of discharge in % (A fully discharged battery has 100% DOD)

CC= Charge current, the current output of the charger in amps. (charge current depends on battery size and breaker size settings)

Example for 12V model:

The battery bank is made up of two 8D Group size batteries with a rated capacity of 200 amp/hours each. The bank is 80% discharged (i.e. DOD = 80). The approximate charging time with the Prosine inverter/charger will be:

400 × 80 =4 hours

100 × 80

Operating Limits for Charger Operation

Output Current: The maximum output current for the Prosine 2.5/12 is 100 amps and the Prosine 3.0/12 can deliver 120 amps. The maximum output current for the 24V Prosine 2.5/24 is 50 amps and the Prosine 3.0/24 can deliver 60 amps. The total output can be reduced by changing the battery size or maximum AC input current (breaker) selection switches.

Input Voltage: The wide input voltage range specification allows the Prosine inverter/charger to deliver a precise charge to your batteries even when incoming AC voltage is less than ideal. The Prosine inverter/charger maintains the correct charging voltage for your battery when the AC line voltage drops as low as 90VAC, or rises as high as 135VAC. A built in surge protector in the Prosine inverter/charger protects it, and your DC circuits, from surges and spikes on the AC power line.

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.
