Introduction

Battery Temperature Compensation

The optional Battery Temperature Sensor (BTS) automatically adjusts the charging process of the C-Series controller. With the BTS installed, the C-Serieswill increase or decrease the battery charging voltage depending on the temperature of the battery to optimize the charge to the battery and maintain optimal performance of the battery.

If not using the BTS, the voltage settings for charging will need to be adjusted based on the temperature of the environment around the batteries and on the type of batteries being used.

See “Temperature Compensation” on page 33 for information on how to set the voltage.

Manual or Auto Equalization Charge

The C-Seriescontroller can be used to manually or automatically provide the battery bank with an equalize charge. Factory default setting is for MANUAL Equalization charging. Be sure to be familiar with all the cautions and warnings concerning equalization charging batteries or damage to batteries can occur.

Load Control Mode

In the Load Control mode, the C-Seriescontrols when to remove a load or loads from the system when an over-discharge or over-load situation occurs. The C-Seriescontroller uses the user-adjustable setpoints to determine when to connect or reconnect loads depending on battery voltage. A load controller prevents damage to the battery from over-discharge during periods of poor weather or excessive loads. The unit does not charge the batteries when in this function.

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.
