Building a case that has 5 Handheld radios with a 50W mobile radio on the top. I have a 12V solar panel. Is it possible to wire the solar panel to the radio and put it on a switch so that you can change from uninterrupted power (house current) to the solar panel to power the radio? Looking for the easiest and cheapest way to do this.
You have a battery basically. Probably a deep cycle marine or golf-cart type batter, maybe 100 to 150Ah.
The battery will have enough capacity to power your load for an adequate time, to power the mobile radio, and charge the hand held radios. Depending, you may need an inverter to run the chargers, but good handhelds should have 12V charging options. The radios would take their power from the battery continuously, regardless of AC power, solar power, or lack of either.
The AC supply and solar panel will basically be paralleled.
The AC will be a supply suitable to charge your battery type and power a load. A 10A 13.8V regulated supply will do most likely.
Solar might be 40W of panels (more if needed), and a charge controller.
If it were me, I would add a circuit that would give preference to solar charging of the battery.
