How to Choose Solar Generators for RVs
Power Output and Capacity
Your power needs determine the minimum wattage and battery capacity required. Calculate the total wattage of devices you’ll run simultaneously, then add 20% buffer for surge power.
Small RVs with basic needs (lights, phones, laptops) work fine with 300-500W generators. Full-time RVers running refrigerators, microwaves, and air conditioning need 1500-1800W minimum with 1000Wh+ battery capacity.
Battery Type and Lifespan
LiFePO4 (lithium iron phosphate) batteries last significantly longer than standard lithium-ion. They provide 3000+ charge cycles compared to 500-1000 cycles for regular lithium batteries.
This translates to 6-10 years of daily use versus 2-3 years. While LiFePO4 units cost more upfront, they deliver better long-term value for frequent RV travelers.
Solar Input Capability
Higher solar input wattage means faster recharging from the sun. Look for at least 200W solar input for weekend trips, or 400-500W for extended off-grid camping.
Check compatibility with your existing solar panels or factor in panel costs. Some generators include solar panels while others require separate purchases, significantly affecting total investment.
Charging Speed and Methods
Fast AC charging gets you powered up quickly at RV parks. Look for generators that reach 80% capacity in under an hour if you frequently move between campgrounds.
Multiple charging options (AC, DC car port, solar) provide flexibility. The ability to charge while driving via your RV’s 12V system maximizes convenience on travel days.
Weight and Portability
Lighter generators are easier to move in and out of your RV. Units under 10 pounds work great for small campers, while 20-30 pound models suit larger RVs with more storage space.
Consider folded dimensions for storage alongside weight. Compact designs maximize precious RV cabinet and compartment space when not in use.
Frequently Asked Questions
What size solar generator do I need for an RV?
Most RVers need 1000-1500Wh capacity with 1500-1800W output to run essential appliances like refrigerators, laptops, and lights. Weekend campers can manage with 300-500Wh units for basic electronics.
Can a solar generator run an RV air conditioner?
Standard RV air conditioners require 2000-3000W to start and 1500W to run continuously, exceeding most portable solar generators. Only the largest units with 2000W+ output and X-Boost technology can handle AC units.
How long does it take to charge a solar generator with solar panels?
A 1000Wh generator with a 400W solar panel charges in 3-4 hours of direct sunlight. Smaller 200W panels take 6-8 hours while cloudy conditions can double these times.
Are LiFePO4 batteries better for RV solar generators?
Yes, LiFePO4 batteries last 3000+ cycles versus 500-1000 for standard lithium, providing 6-10 years of service. They’re safer, more temperature-stable, and offer better long-term value despite higher initial costs.
Can I use a solar generator while it’s charging?
Most modern solar generators support pass-through charging, letting you use devices while the battery recharges. This feature is essential for continuous power during extended RV stays.
Final Thoughts
The EcoFlow DELTA 3 Classic offers the best overall performance with 1800W output and 45-minute fast charging for serious RVers. Budget-conscious campers should consider the Grecell 330W complete kit with included solar panel.
Choose based on your power needs, travel frequency, and budget. LiFePO4 batteries and higher solar input justify premium prices for full-time RV living, while smaller units serve weekend adventures perfectly.
Investing in quality solar power transforms your RV experience with true off-grid freedom. Match your generator capacity to your lifestyle and you’ll enjoy reliable power wherever your travels take you.
