Designing the Installation

All installations of the Prosine inverter/charger system share many common components, described briefly in this section. AC & DC cabling, circuit breakers, fuses, and distribution panels are more fully described in following sections. The figure below diagrams a typical residential installation showing these components and their relationship to each other in a typical installation.

AC Shorepower A source of 120-volt, 60-Hz alternating current is necessary to provide a source of energy for charging batteries, and to pass-through to AC loads. This source could be the utility grid or power company, or a gasoline-, diesel-, or natural gas-powered AC generator. Multiple sources of shorepower may also be available.

AC Disconnect and Overload Device Every system requires a method of disconnecting the AC power source, and an overload protection device (circuit breaker or fuse). These two components are often integrated into an AC circuit breaker, which provides a disconnect and protects against overload at the same time. These devices are usually installed within a protective box. Some provide a method of selecting between multiple AC sources as well as circuit protection and disconnect. You can use up to a 30-amp circuit breaker in the AC supply line feeding the inverter/charger. The current rating of the breaker or fuse must be matched to the wire size(s) involved, in accordance with the applicable installation codes.

AC Distribution Center The AC distribution center is often called a ‘main panel,’ or a ‘sub panel.’ A main panel includes a main circuit breaker, which serves as a disconnect for the AC power supply line. Additional circuit breakers serve individual circuits, one of which may serve the inverter/charger. Some systems route all AC service through the inverter/charger, in which the main AC distribution panel is fed by the inverter/charger AC output. In all systems, both the inverter/charger and the AC loads on the inverter/charger must be protected with circuit breakers.

AC Cabling AC cabling includes all of the wires and connectors between the AC source and the inverter/charger; and between the inverter/charger and the AC distribution panels, circuit breakers, and loads. The type and size of the wiring varies with the installation and the load. For marine and some RV applications, flexible multiple-strand wire known as ‘boat cable’ is required. For residential installations, solid ‘ROMEX’ cable is often used. Your installation code may specify the number of strands, the overall size of the conductors, and the type and temperature rating of the insulation around the wire.

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.
