When you measure up the space you have available on your roof or elsewhere, you may find it difficult to capture the power required to run your RVâs house systems completely off of solar power. For a large motorhome, you might need 500 to 800 watts of power.
For your RV you need 110 Volt at 30 Amp. also 3300 watts, but they are setup with two 110v receptacles with a 13 amp breaker one on each hot wire. So for 110v use you would have to split the load between the two receptacles. with a 50Amp RV you would have to limit the load to 13A.
