AN ALTERNATIVE POWER SOURCE is essential for extending camping trips. While traditional generators and battery power stations are common, they have drawbacks compared to RV solar generators.
Gas or propane-powered generators produce noise and emissions and require fuel storage. Portable power stations typically need recharging from an AC outlet and often lack the capacity for larger RV appliances. Meanwhile, solar generators provide quiet, emission-free power at a higher wattage rating and can recharge directly from sunlight instead of relying on LP or gas.
Many RVers will use a combination of these portable power sources, so let’s explore if a portable solar power generator is a worthy addition to your camping checklist.
Key Takeaways
- RV solar generators provide quiet, eco-friendly power for camping and are ideal for recharging electronics and running small to mid-size appliances without noise, fumes, or fuel dependency.
- Top solar generator picks vary by use case, from budget-friendly and compact models like the ACOPOWER and EcoFlow River 2 to high-capacity options like the EcoFlow DELTA Pro that can power entire RV systems.
- Compared to inverter generators, solar generators offer clean operation with minimal maintenance. However, inverter generators remain better suited for high-wattage demands like air conditioning, making a hybrid power setup ideal for most RVers.
What Is a Solar Generator?
A solar generator is a portable power system that uses solar panels to charge a battery, which then supplies electricity through built-in A/C outlets, DC ports, or USB connections. It typically includes four main components: solar panels, a battery, a charge controller, and an inverter.
For RVers, solar generators offer a quiet, eco-friendly alternative to gas-powered generators. They allow for off-grid camping without fumes or fuel costs.

Solar Generator vs Inverter Generator
Images by Camping World
Many campers struggle to decide between a solar generator and an inverter generator.
A solar generator consists of a battery bank, an inverter, a charge controller, and one or more solar panels. The system converts sunlight into electrical power, which is stored in the battery and later used to power devices and appliances. Because no fuel is burned, solar generators operate silently and emit no exhaust — a considerable advantage in quiet campgrounds and national parks.
An inverter generator, on the other hand, runs on gasoline or propane and produces A/C power through an internal combustion engine coupled with an inverter. It offers continuous, reliable power at higher wattage levels, making it well-suited for running energy-hungry RV systems like air conditioners.
Key Differences
| Feature | Solar Generator | Inverter Generator |
| Noise Level | Silent | Moderate (50-70 dB) |
| Fuel | Solar-powered | Gasoline or propane |
| Maintenance | Minimal | Regular oil/filter changes |
| Emissions | None | CO2 and fumes |
| Power Output | Lower overall | Higher for large loads |
| Cost | Higher upfront | Lower upfront |
Suitability for Different RV Lifestyles
Solar generators excel for campers who prioritize quiet, eco-friendly operation. They’re ideal for powering electronics like phones, laptops, lights, and CPAP machines, and they allow RVers to camp in sensitive areas where fuel generators may be restricted. With no ongoing fuel costs, solar generators can also pay off for full-timers who frequently boondock. Solar generators are unmatched for quiet, clean power during daytime use and overnight device charging.
Inverter generators shine when you need robust power on demand. A fuel-powered inverter generator will likely be more practical if you plan to run your RV air conditioner, microwave, or other high-wattage appliances for extended periods. They also recharge instantly with a full gas tank, whereas solar generators depend on available sunlight. For high-wattage, whole-RV backup, an inverter generator remains the more versatile choice, especially in poor weather or heavily shaded camping locations.
Many RVers employ a hybrid approach: using a solar generator for everyday power and keeping an inverter generator on hand for backup or air conditioner use. This gives you the flexibility to enjoy the best of both worlds.
Can I Run My RV AC With a Solar Generator?
Only a high-capacity solar generator like the EcoFlow DELTA Max or DELTA Pro can run average RV air conditioners. Running a 13,500 BTU RV air conditioner typically requires 2,500-3,00 surge watts and 1,300 to 1,500 running watts. A larger air conditioner will pull more power when starting up and running.
Look for a generator with at least a 2,000-watt-hour capacity and a surge rating above 3,000 watts. Even then, sustained air conditioner use will drain batteries quickly unless paired with high-output solar panels and optimal sun exposure.

What Size Solar Generator Do I Need for My RV?
In addition to choosing a solar generator with the correct output to run your air conditioner, you’ll also need to look at capacity to ensure you have enough stored power to meet your needs. Here’s a quick guide:
- Weekend Warriors (Phones, Lights, Fans): 150Wh–500Wh
- Digital Nomads (Laptops, Routers, Small Appliances): 500Wh–1,000Wh
- Full-Timers (Fridge, Microwave, Coffee Maker): 1,000Wh–2,000Wh
- Whole RV Backup (AC, TVs, etc.): 2,000Wh+
Calculate your needs by adding the wattage of all devices you want to run, then multiply by the hours of daily use to get your Wh/day estimate.
