Thus as a practical matter the vast majority of rv owners will never be able to set up their rv in a way that solar could power an ac unit.
Solar rv ac unit.
And the air conditioner is on a 20 amp breaker not a 15 amp.
Kingtec solar powered air conditioner for rv.
For example many rv air conditioning units require somewhere between 1 700 and 3 500 starting watts and 600 to 1 500 running watts.
So the air conditioner pulls 150 amps from the 12v batteries the inverter transforms that current into 15 amps 120v and then sends it on to power the air conditioner.
We are talking rv solar here the power source is a 12v battery bank.
It takes a minimum of 750 watts to do it and 10.
You can just drop it over the roof vent hook up the power and enjoy the cool air in your rv.
These two factors along with the size of the panels you install will dictate how many panels you need to effectively use solar power for rv air conditioner power supply.
However the number of panels needed to power the rest of the rv let alone keep the ac unit running all day would be pretty high.
While it is technically possible to power an rv air conditioner with solar panels to generate enough power a large amount of solar panels and upgrades to the electrical system would be required.
