Temperature Compensation Based on Battery Type

The C-Series controller uses the battery type to determine the temperature compensated voltage settings. The temperature compensated charging voltage is normally based on a Lead – Acid types of battery.

If using Alkaline-type batteries, the R46 resistor on the circuit board inside the controller will have been clipped as shown in “Setting Voltage Parameters for Alkaline Batteries” on page 26. If the R46 resistor is cut, the temperature compensation charging voltage will be based on Alkaline-type batteries.

See the battery type below to determine the temperature compensation value change per temperature or refer to the temperature compensation calculations for a Lead-Acid type battery as show in Table 2-2.

Lead-Acid Type Batteries:

5 mV per cell per degree Celsius

Alkaline -Type Batteries (NiCad or NiFe): 2 mV per cell per degree Celsius

Table 2-2describes approximately how much the voltage may vary depending on the temperature of the batteries.

Automatic Battery Temperature Compensation

Temperature compensation can be accomplished automatically by using a Battery Temperature Sensor (BTS). The sensor attaches directly to the side of one of the batteries in the bank and provides precise battery temperature information.

See “Installing the Battery Temperature Sensor” on page 51 for detailed instructions on how and where to install the BTS.

If a BTS is installed, the charge controlling process will be automatically adjusted for the battery temperature. When using a BTS, set the Bulk and Float voltage for a battery at normal room temperature for 77 °F (25 °C).

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.
