Anybody using these batteries?
You need to multiply by the duty cycle, the radio does not broadcast continuously. Also there is some residual power that the radio uses just being powered on.Simple Math:
12V * 20Ah = 240 Watt Hours.
240 Watt Hours / 35 Watts (the Radio) = 6.85 Theoretical Working Hours. So no, not all day at 35 Watts.
But do what I do, and either get higher voltage battery (no higher than 16V input that the radio requires) and / or lower your output power.
You could run that at 25 Watts and get 9.6 Hours and still have great radio power.
I would think you would want at least a 50 watt panel to be able to produce enough power on shady days. I would pair it with a 40Ah 12V deep cycle battery.Would it be possible to run a 10 watt radio 10-12 hours a day from a remote location using solar to charge the batteries?
How many batteries would be needed and what size solar solar?
A solar charger, WITHOUT a "Monitor", or a voltage regulator, can over volt the battery. I think the radio can handle up to 20 volts, it indicates that it is do-able, but a regulator would be a good idea.Thanks Matt. I was thinking that two 12volts in parallel with a 100w panel should be more than enough.
