Generators are the most practical way to have enough power to run very high-wattage appliances like the air conditioner, microwave oven and of course power all of your 120-volt AC devices (laptop, tvs, etc.).
If you must have air conditioning when not plugged in, you will have to use a generator, and it will need to be capable of at least 3,000 watts.
However, if you can live without your air conditioner and microwave oven, solar panels become a very attractive option.
Solar panels are silent, don’t require you to carry fuel, and are virtually maintenance free (other than washing them once in a while).
They work without any intervention from you and can keep the batteries in your RV charged while it’s in storage.
If you want to get a generator, do yourself and your neighbors a favor and get one of the quieter models specifically made for RV use.
Solar’s big advantage is in recharging batteries. It can take up to 12 hours to fully charge your RV battery.
Rather than pumping out large amounts of power in short time periods like a generator, solar provides a steady all-day charge and will have a much better chance of getting your batteries up to 100%.
With batteries, slow and steady wins the race.
