Well did some size testing, the dry box i picked up is a bit larger than expected (good thing). I am able to fit my radio, meter, dipole antenna as well as my 40ah lifepo4 battery from my first go box plus an inverter that i picked up. This will allow me to have a power station for cells and laptops etc. If i go with this larger battery in the box, what size panel would i need to keep it topped off during field use? I think i have my calculations down but not sure as this is my first dive into solar. Here it goes:
40Watt Panel/ 12 Volts= 3.3 Amperes
40 amp hour Battery/ 5Amperes=12.1 hours of charge time approx.
I know that there are discharge factors that would reduce this overall charge time, but then again i am only looking at keeping this battery topped off.
As far as power draw, i am going legal limit cb/ssb so 12amps max and that would be only on TX...
Does this sound like it would work?
