Quick Answer
GMRS radios can technically operate while charging in solar setups, but several factors must be considered to ensure reliable performance and communication.
Solar Panel Requirements
To power a GMRS radio while charging, you’ll need a sufficient solar setup. A minimum of 2-3 amps of charging current is recommended for most GMRS radios. Use a 12V solar panel with a minimum 10W rating, such as the Renogy 10W Solar Panel. This setup will provide a stable 12V power source for your GMRS radio.
Charging Circuit and Battery Considerations
When designing a solar-powered charging circuit for your GMRS radio, ensure it’s a simple, low-voltage circuit that won’t compromise the radio’s charging efficiency. Use a 12V, 2-3A charge controller like the Renogy 12V 10A Charge Controller. Connect the solar panel to the charge controller, and then to the battery. Use a deep cycle battery with a minimum Ah rating of 20, such as the Odyssey 20Ah Battery. This setup will ensure reliable charging and prevent overcharging the battery.
Powering a GMRS Radio from a Solar Panel
To power a GMRS radio from a solar panel, you’ll need to connect the solar panel’s output to a voltage regulator. Use a 12V DC-to-DC voltage regulator like the Mean Well 12V 5A Switching Power Supply. Connect the voltage regulator to the solar panel, and then to the GMRS radio. This setup will provide a stable 12V power source for your GMRS radio, ensuring reliable performance and communication.
