Section 4: Inverter/Charger Installation

For best performance, the wire sizes shown in the table below will allow the Prosine to operate properly. Please note that regulatory requirements may not allow you to use the wire size given for 5 foot and 10 foot distances. Also, increasing the wire size will provide longer inverter performance.

DC Disconnect

If a DC circuit breaker is used to provide over-current protection for the battery circuit, it will also meet the requirement to provide a disconnect. If a DC fuse is used to provide over-current, however, a separate DC disconnect switch or a combined “fusible disconnect” will be required. As with the AC disconnects, the DC disconnect is not intended for disconnection under load.

Battery Cable Routing

When a distance separates positive and negative battery cables, they have much more inductance than if they are close together, and when the high current drawn by the inverter is flowing, strong magnetic fields are generated. These fields may interfere with sensitive equipment, so it is very important to route the positive and negative cables in parallel, as close together as possible.

DC Cabling Connections

Color-code your battery cables with colored tape or heat shrink tubing. The standard is red for positive (+) and black for negative (–).

Use crimp-on ring terminals or set-screw type pressure connectors (i.e., “box lugs”).

For marine installations, you must use a wire protector between the set-screw and stranded wire.

If you are using crimp-on terminals, use the manufacturer’s recommended crimping tool to install them.

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.
