Batteries

NiCad and NiFe Batteries

The Xantrex C-Series is compatible with NiCad (nickel-cadmium) NiFe (nickel-iron) and alkaline-type batteries, which must be charged to a higher voltage level to achieve a full charge.

To use the C-Series with NiCad batteries, clip the wire on the resistor labeled “R46” in the middle of the C-Series circuit board by cutting it. See “Setting Voltage Parameters for Alkaline Batteries” on page 26 for instructions on how to clip this wire.

Avoid damage to neighboring components.

Important: In all applications the BULK voltage setting should be adjusted to a level below the maximum operating voltage of the DC loads. This may be as low as 15 volts for some types of electronic loads. Undercharging may occur in this instance, but DC equipment will be protected. Check with the manufacturers of the DC equipment being powered for its maximum DC input voltage tolerance. If equalization is expected to occur, then the DC equipment being used must tolerate the voltages which will occur during the equalization process.

Battery Sizing

Batteries are the fuel tank of the system. The larger the batteries, the longer the system can operate before recharging is necessary. An undersized battery bank results in short battery life and disappointing system performance.

To determine the proper battery bank size, compute the number of amp-hours that will be used between charging cycles. Once the required amp hours are known, size the batteries at approximately twice this amount. Doubling the expected amp-hour usage ensures that the batteries will not be overly discharged and will extend battery life.

C35, C60, C40 specifications

Xantrex Technology is a renowned name in the field of renewable energy solutions, particularly known for its robust line of solar charge controllers. Among its flagship products are the C-Series models: C40, C60, and C35. These charge controllers are specifically designed to optimize the use of solar panels, ensuring efficient energy conversion and battery management for off-grid renewable energy systems.

The C40 model stands out with its impressive 40-amp rating, making it suitable for larger solar installations. It features advanced microprocessor technology, enabling precise control over battery charging and discharging processes. This model supports multiple battery types, including flooded lead-acid, gel, and sealed batteries, allowing users to customize their energy systems according to their specific requirements. One of the key characteristics of the C40 is its easy-to-read LCD display, which provides real-time information on system performance, battery voltage, and charging status.

Moving to the C60, this model offers a higher capacity, rated at 60 amps. The C60 is designed for larger applications, such as RVs, boats, and remote cabins, where higher power requirements are common. It shares many features with the C40 but is equipped with additional capabilities to enhance its versatility. One notable characteristic is the built-in load control, which allows users to manage power distribution to connected devices intelligently. The C60 also incorporates a temperature sensor that adjusts charging parameters according to the battery’s temperature, protecting it from overcharging and extending its lifespan.

The C35, while a bit smaller with a 35-amp rating, is designed to cater to medium-sized applications. It offers similar functionalities as its counterparts, including support for multiple battery types and an intuitive LCD display. The C35 is an ideal solution for homeowners and small businesses looking for reliable performance without the need for extensive power management.

All three models feature a durable design, built to withstand the rigors of outdoor use. With a focus on user-friendly operation, these charge controllers come equipped with straightforward installation processes, making them accessible to both seasoned professionals and newcomers to solar energy. Additionally, their capability to integrate with various solar panel systems makes them a flexible choice for diverse renewable energy applications. With Xantrex’s C-Series charge controllers, users can reap the benefits of solar energy while ensuring their battery systems remain healthy and efficient.
