Best Solar Generator for RV: EcoFlow DELTA Pro Bundle
There are many backup power options for RVs, and the EcoFlow DELTA Pro power station bundle is one of the best. It includes two DELTA Pro units for double the power. Specifically, that's 7,200 watt-hours, 7,200 running watts, and 14,400 starting watts--enough to power two 15K BTU air conditioners for your RV.
What makes this bundle even more geared toward RVs is the TT-30R receptacle, which lets you plug your vehicle in directly without needing to purchase a separate adaptor. You can recharge the Delta Pro using a wall outlet, which will charge it in under two hours, solar panels, or a car charger. If you opt for the solar option, you can connect up to four 400-watt EcoFlow solar panels (sold separately) or use an MC4 connector with other panel brands.
There are a whopping 14 output receptacles on the DELTA Pro that will accept everything from smartphones to pressure cookers to portable radios--anything you might want while on the road. If your battery needs extra power, then X-Boost technology can provide a surge of wattage (up to 4,500 watts per individual DELTA Pro unit). Just keep in mind that using the X-Boost feature will drain your battery faster.
Each DELTA Pro unit weighs less than 100 pounds, and the EcoFlow app makes it easy to control and monitor your power stations once they're running. Overall, this is a simple, clean, and powerful solution for powering your RV, but it does come with a steeper price tag.

How We Picked the Best RV Generators
*Disclaimer* Some recreational vehicles are only compatible with specific generator models, so please investigate and ensure the generator you want is compatible with your RV before purchasing.
When recommending RV generators, we take the following features into account:
Power
RV generators must have the power to run all critical appliances while in remote locations, such as running an air conditioner, shower or toilet, electric stove, lights, septic plumbing apparatuses, and more. As such, we consider each generator’s power potential, measured in running wattage, which is how many watts the generator can produce continuously at various loads. We also consider frequency and whether the generator can safely power sensitive electronics like laptops and cell phone chargers.
The important thing to remember here is that an RV generator should be sized appropriately to handle the electrical load of all appliances found in the vehicle. Most owner's manuals will list the wattage requirements of the generator they recommend (or require) for your recreational vehicle.
Noise
Increasing noise regulations around the country make “loudness” an important factor to consider when choosing the right generator. RV parks, municipalities, and national parks can all have their own decibel regulations.
Especially when you are close to neighbors on campsites, you'll want a quiet RV generator you can run all night without waking everyone up. Certain features are highly regarded for these purposes, like sound-attenuating enclosures and start mufflers, as well as engines designed with quiet in mind. Although not all manufacturers list their decibel ratings, we try to consider noise levels when recommending generators.
Usability
Certain features help ensure built-in RV generators are more user-friendly, such as remote starting capability, digital voltage regulators, and easy operation features like a one-touch start or stop button on the control panel. At the end of the day, the generator needs to work well and be simple to use so you spend less time struggling to start it and more time enjoying the equipment it powers.
Similarly, the best portable RV generators must be easy to move and operate, whether you or your elderly grandparents are using them. They can’t be so heavy or awkward that you can’t move them. If they are heavy, there should be wheels, an ergonomic handlebar, or handles on both sides for multiple movers. Features like push-button start, a large fuel tank, surge protection, and simple controls can all make the difference between a useable portable generator and an electrical headache.
Versatility
Versatility answers the question, “How adaptable is this generator to different situations?” An RV generator must be compatible with your recreational vehicle and compliant wherever you drive it. We look for models with universal mounting trays that ensure easy installation and compatibility with various requirements.
For portable camping generators, we also consider the generator receptacle outlets, which determine what and how much you can plug into the unit. You want a mix of standard household outlets, where you can plug in things like a microwave, and heavier-duty locking outlets that can handle 240 volts.
Overall Value
We prioritize performance over price, so you won’t necessarily find the cheapest RV generators on our list. That's why, instead of evaluating a generator on price alone, we look at what you're getting for the price to arrive at an overall value rating.
RV Generator FAQs
Can You Run an RV Generator While Driving?
You can run a built-in RV generator while driving to power your air conditioner and other larger appliances. Just keep in mind that, because your RV generator will likely pull fuel from the same tank as your RV, you will run out of gas faster.
If your built-in RV generator runs on propane, check your local laws because there may be safety restrictions with operating it while driving. If you have a portable RV generator, you can’t run it while driving because it must be outdoors to exhaust. Never put it in an enclosed or even partially enclosed space, as this could lead to injury or death.
What Size Generator Do I Need for My RV?
A built-in RV generator needs to fit inside the compartment on your RV. So, always measure the physical dimensions of your generator compartment before starting to shop for one. Portable RV generators don’t have this restriction, but, in practice, you’ll want a lighter-weight generator for easier transport. For more help with sizing, visit our RV generator buyer's guide.
