So if you have a 100ah rv battery you can charge 50 of it in a little over 8 hours 50ah 6a 8 33.
How many watt solar panel do i need to charge deep cycle battery.
Typically a 300 watt solar battery charger can recharge deep cycle lead acid or lethem ion battery.
Solar charge deep cycle battery use multi stage solar charge controller which send as much available solar energy as possible to the deep cycle batteries bank for recharging.
This means that on that scenario the solar panel delivered 60 watts of power to charge the battery.
If you were using 200 watt panels you would need only three panels and four 300 amp batteries.
50 is 50 of our 100ah battery and 6 is how many amps the 100w solar panel is generating.
In this video i show the renogy 100w panel and how to connect it to a camper.
A typical panel can put out 120 watts so it would take about 20 hours of sunlight to charge the battery.
100 amp hours useable or 1280 watts of battery in 6 hours you will need 213 watts of solar panels.
That is about 2400 watt hours.
Well add about 50 for things like charging losses and clouds.

213 watts of solar x 6 hours 1280 watts of stored power 213 watts of solar x 6 hours 1280 watts of stored power.
