Quick Answer
A 100W solar kit can be connected to an RV battery, but it's essential to consider the battery type, compatibility, and system configuration.
Choosing the Right Battery
When selecting a battery for your RV, look for deep cycle batteries rated for off-grid use. A 12V, 100Ah or larger battery is recommended for a 100W solar kit. For example, a Battle Born 12V 100Ah lithium battery or a Trojan T105 12V 100Ah AGM battery would be suitable choices.
System Configuration and Safety
To connect a 100W solar kit to an RV battery, you’ll need a charge controller, wiring, and fuses. A 30A or 40A charge controller, like the Renogy 40A Rover Li, is sufficient for a 100W solar kit. Use 10AWG or 8AWG wiring to connect the solar panel to the charge controller and the charge controller to the battery. Install fuses (15A or 20A) near the charge controller and battery to protect against overcharging or short circuits.
Powering Your RV
Once your system is configured, you can start harnessing solar power to charge your RV battery. Aim for direct sunlight, and adjust the solar panel’s angle to optimize power generation. With a 100W solar kit, you can expect to generate around 1-2Ah of power per hour, depending on the sunlight conditions. This can help keep your RV battery charged, especially when boondocking or off-grid.
