Section 7: Batteries

Monthly Battery Maintenance

WARNING Wear appropriate attire and eye protection. Use caution when working with metal tools around batteries. Do not allow any metal object to come into contact with both battery terminals at the same time. Battery explosion or failure can occur.

At a minimum, check the level of the electrolyte in each battery cell once a month (for non-sealed batteries). It should be above the top of the plates, but not completely full. Most batteries have a plastic cup that, when full, just touches the electrolyte. Don’t overfill the batteries or the electrolyte will spill out of the batteries when they are being charged. Refill the batteries with distilled water only— “spring” water and regular tap water may have high levels of minerals that can poison the battery chemistry and reduce battery life.

It is also good to periodically check the battery connections for tightness and corrosion. If any corrosion is found, disconnect power from the Prosine, disconnect the cables, and carefully clean with a mild solution of baking soda and water. Do not allow the solution to enter the battery. Rinse the top of the battery with clean water when finished.

To reduce the amount of corrosion on the battery terminals, after reassembly, coat them with anti- corrosion grease or liquid neoprene (liquid electrical tape) available from automotive parts stores or battery suppliers. Do not apply anything between the terminal and the cable lugs. The connection should be metal to metal. Apply the protective material only after the bolts have been tightened.

Cleaning Batteries

Dirty batteries may leak current, and tend to run warmer. Cleaning the batteries, when necessary, is easy and safe when the instructions presented here are followed.

Preparation

You will need appropriate attire, a few tools, and some equipment and supplies on hand. Read over the list and gather what you need before you begin.

WARNING Wear appropriate attire and eye protection.

Attire

Appropriate attire might include old clothes, rubber boots or old shoes. Battery acid is very corrosive and will dissolve most textiles within a few days after exposure, so wear something you can live without just in case you splash some on yourself. Be sure to wear rubber gloves and eye protection.

Tools

p½-inch and/or 9/16 wrench as required, or an equivalent socket and ratchet

padjustable and/or locking pliers

ptorque wrench (suggested, not required)

psoft-bristled brush (discarded toothbrushes work just fine)

p6-inch scrub brush

pinexpensive ½ inch chip brush or soldering brush

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.
