Common Concerns Answered
Is PWM technology the most efficient for my solar setup?
PWM technology is highly effective in stable, direct sunlight. For systems experiencing frequent low light or highly variable conditions, MPPT controllers generally offer higher efficiency, though this unit's robust protections and 3-in-1 functionality provide significant advantages for many marine applications.
Does this controller have advanced display features?
The Xantrex C35 features a standard multi-color charge status LED faceplate for clear, at-a-glance indication. For more detailed digital readouts or remote monitoring, higher-end models with integrated displays or connectivity may be considered.
Can I upgrade to a larger solar array with this controller?
The Xantrex C35 is rated for 35 Amps. If your solar array's output exceeds this capacity, you would need to consider a controller with a higher amperage rating to ensure optimal performance and safety.
Frequently Asked Questions
What is the maximum solar panel wattage this controller can handle?
To determine the maximum solar panel wattage, divide the controller's amperage rating (35A) by the system voltage (12V or 24V), and multiply by the voltage efficiency factor. For a 12V system, it can handle approximately 420W (35A * 12V) and for a 24V system, approximately 840W (35A * 24V), assuming optimal conditions. Always refer to your solar panel's specifications to ensure compatibility.
Can this charge controller be used with lithium-ion batteries?
The Xantrex C35 is compatible with various battery types, including lithium-ion, provided the voltage set points are adjusted accordingly. It's crucial to consult the manual and your lithium-ion battery's specific charging requirements for correct configuration.
What is the operating voltage range for this controller?
The controller is field configurable for 12V and 24V nominal battery systems. The maximum PV open circuit voltage it can safely handle is 100V (when used with a 24V system).
Does this controller have a remote display option?
No, the Xantrex C35 does not have an integrated remote display option. It features a multi-color charge status LED on the faceplate for system monitoring.
What types of battery systems is this controller compatible with (e.g., flooded, AGM, gel)?
This controller is compatible with a wide range of battery types, including flooded lead-acid, AGM, and gel batteries, as well as lithium-ion batteries. The specific charging parameters can be field adjusted to suit the chosen battery chemistry.
