How Large a Generator Should I Purchase for My RV?

Power Everything in Your RV

People who take their RV to remote locations and want to power the RV as it was designed can calculate the size generator they need. Consult the RV documentation to determine the total electrical load needed. Purchase a generator that will supply that load. Keep in mind that each appliance has a starting electrical load that is higher than the load needed for continuous operation. Generators to power an entire RV can require over 3000 W.

Charge Your Batteries

Some RV owners who travel to remote locations are willing to only use the RV systems that run from the batteries and from propane. This only requires a generator that is large enough to power a charging system to keep the batteries full. A 400 W generator powering a smart charger is generally large enough to accomplish this task.

Bottom Line

The size generator needed to power an RV depends on the power requirements of the user. If the camper plans on using the television, microwave and air conditioner, then a large generator will be needed. If the camper will only be using DC lighting, water pumps and a propane refrigerator, then a much smaller generator will fulfill their needs.
