Quick Answer
When selecting an RV solar kit, look for features such as sufficient wattage for your energy needs, a charge controller that matches your panel's voltage, and a wiring system that meets or exceeds RV fire safety standards.
Choosing the Right Solar Panel Wattage
When selecting an RV solar kit, the first consideration is the total wattage of the solar panels. A good rule of thumb is to choose an RV solar kit with a minimum of 100 watts of solar panel power per 10-12 volt deep cycle battery, and 300-400 watts for larger systems. Consider the energy needs of your RV or cabin, taking into account the number of devices you’ll be powering, such as lights, fans, and appliances. For example, a small RV might require 200-300 watts, while a larger cabin might require 600-1000 watts or more.
Charge Controller Compatibility
Another crucial consideration is the charge controller. Make sure it matches the voltage of your solar panels, typically 12 or 24 volts. Renogy solar panel kits often come with a charge controller, but it’s essential to verify compatibility. A mismatch can lead to reduced system efficiency, overheating, or even damage to the controller. Look for a charge controller with a high surge capacity (such as 60 amps) to handle peak solar panel output.
Wiring and Safety Considerations
Finally, consider the wiring system. RV solar kits often come with a pre-assembled wiring harness, which can be a convenient option. However, it’s essential to inspect the wiring and ensure it meets or exceeds RV fire safety standards, such as those set by the National Fire Protection Association (NFPA). Look for wiring with a minimum of 12 AWG (American Wire Gauge) for 12-volt systems, and ensure that it’s properly secured and protected from damage. This will help prevent electrical fires and ensure a safe and reliable solar power system.
