Section 4: Inverter/Charger Installation

gauge number indicates a smaller wire diameter (for example: a 2 AWG cable is smaller than a 00

AWG cable). Under the MCM standard, a larger number indicates a larger cable (example: a 350 MCM cable is larger than a 250 MCM cable). Wire size is usually marked on the cables for sizes this large.

DC Disconnect and Over-Current Device The DC power supply leading to the inverter/charger must also be equipped with a disconnect and over-current device. These usually consist of a circuit breaker or a fuse and disconnect. Do not confuse AC circuit breakers with DC circuit breakers. They are not interchangeable. The Prosine inverter/charger requires a DC over-current device rated at least 300-amps. This can be a fuse in the positive DC cable, or a DC breaker in the same line.

Batteries Every Prosine inverter/charger system requires a deep-cycle battery or group of batteries that provide the DC current that the inverter/charger converts to AC current. There are different types and sizes of batteries, many of which are discussed in ”Section 7: Batteries”. Automotive-type batteries are not recommended for use with the Prosine inverter/charger, except for temporary emergency use only. The Prosine inverter/charger utilizes 12-volt or 24-volt battery banks, depending upon the model purchased. Read the label on the side of the inverter/charger to determine the correct battery voltage to use.

Generator When a generator is included as a secondary AC power source, a manual or automatic AC source selector switch must be installed ahead of the circuit breaker in the line leading to the inverter/charger. In marine and RV applications, the AC cabling from the generator to the circuit breaker must be composed of stranded cable. Both the Line (Hot) conductor and the Neutral conductor must be protected by circuit breakers. If the generator is the only AC shorepower source, no source selector switch is needed.

Ground Fault Circuit Interrupters (GFCIs) A GFCI is a device that de-energizes a circuit when a current to ground exceeds a specified value that is less than that required to blow the circuit breaker. GFCIs are intended to protect people from electric shocks.

Installations in marine and recreational vehicles may require GFCI protection of branch circuits connected to the AC output of the inverter/charger. In addition, electrical codes require GFCI protection of certain receptacles in residential installations.

While the true sine wave output of the Prosine inverter/charger is equivalent to the waveform provided by utilities, compliance with UL standards requires that Xantrex test and recommend specific GFCIs. Xantrex has tested the GFCI-protected 15A receptacles listed in Table 2 and found that they function properly when connected to the AC output of the Prosine 2.0.

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.
