Best Solar Generators for RVs and Campers of 2026
A solar generator is the fastest way to add power to an RV without drilling the roof: it is a battery, an inverter, and a solar charge controller in one box that you recharge from a wall outlet, the tow vehicle, or a fold-out panel. For most rigs, a 1,000Wh to 2,000Wh LiFePO4 unit runs the fridge, lights, fans, and devices for a weekend and refills in a few hours of sun. Below are four I would actually buy, sorted by how you camp: a light do-everything unit, a value pick for vans, a big-battery model that can start an air conditioner, and a max-capacity rig for long boondocking. Size yours against your real daily watt-hours with the solar panel calculator.

EcoFlow Delta 2
Who it is for: Weekend and long-trip RVers who want one light unit that runs the fridge, lights, and devices and recharges fast.
- +1,024Wh of LiFePO4 and an 1,800W AC output cover an RV fridge, lights, fans, a laptop, and phone charging for a day or two between charges.
- +At about 27 pounds it is light enough to lift in and out of a storage bay, and it recharges to 80% from a wall outlet in under an hour.
- +Takes up to 500W of solar input, so a couple of fold-out panels top it back up in a sunny afternoon; pair it with a portable solar panel.
- +Expandable: add a DELTA 2 extra battery to reach 2,048Wh when your trips get longer.
Watch out: Its 1,800W inverter will not start most rooftop RV air conditioners. If running the AC is the goal, jump to the Bluetti AC200L below.
Anker SOLIX C1000
Who it is for: Van-lifers and small-camper owners who want a compact 1kWh LiFePO4 unit for the least money.
- +1,056Wh and 1,800W in a compact case that fits under a bench or in a cabinet, at about 28 pounds.
- +Fast wall charging (roughly 0 to 80% in under an hour) and a UPS mode that switches over in milliseconds if you plug into shore power.
- +Expandable to 2,112Wh with a bolt-on battery if you outgrow the base unit.
Watch out: Like the Delta 2, its 1,800W inverter is sized for 12V-style loads and normal appliances, not a rooftop AC. It handles everything short of that.
Bluetti AC200L
Who it is for: Big-rig owners and boondockers who want to run a rooftop AC in bursts and power a residential fridge overnight.
- +2,048Wh and a 2,400W inverter (3,600W with Power Lifting) can start and run a 13,500 BTU RV air conditioner for a stretch, especially with a soft-start installed.
- +Has a built-in 30A NEMA TT-30 outlet, so a standard RV shore-power cord plugs straight in without an adapter.
- +Expandable to 8,192Wh with two add-on batteries for multi-day off-grid stays.
Watch out: Running an air conditioner drains even 2,048Wh fast, so treat AC as short-run comfort, not all-night cooling, unless you add battery and solar. It weighs about 62 pounds.
EcoFlow Delta Pro 3
Who it is for: Full-timers who dry-camp for days and want to run heavy loads without ever touching a gas generator.
- +4,096Wh and a 4,000W output run an RV air conditioner, a microwave, and a residential fridge with headroom, and it rolls on built-in wheels and a telescoping handle.
- +Accepts a large amount of solar input, so a big fold-out array can refill it during a dry-camp day.
- +Stackable with extra batteries into the tens of kWh, so it scales toward whole-rig backup.
Watch out: It is heavy (over 100 pounds) and pricey. Overkill for weekenders; buy the Delta 2 unless you truly dry-camp for days at a time.
What actually matters when buying
What size solar generator do I need for my RV?. Match watt-hours to your daily use. A weekend van running lights, fans, a 12V fridge, and devices is happy on 500Wh to 1,000Wh. Full-timers with a residential fridge usually want 1,500Wh to 2,000Wh so they are not recharging daily, and running a rooftop air conditioner in bursts pushes you to 2,000Wh or more plus real solar to refill it. Add up the watts of what you run and how many hours, then check the total with the solar panel calculator and the runtime math in what a 100Ah battery can run.
Can a solar generator run an RV air conditioner?. Only the bigger ones, and not all night. A 13,500 BTU rooftop AC pulls a large startup surge, so you need a 2,000W-plus inverter with high surge headroom, and a soft-start device makes it far more reliable. The Bluetti AC200L and EcoFlow Delta Pro 3 above can do it; 1,000Wh units like the Delta 2 cannot. Even when the inverter is big enough, an AC eats capacity quickly, so plan on short comfort runs unless you stack extra batteries and a big solar array.
How do you recharge a solar generator in an RV?. Three ways, and most owners use all three. Shore power or a wall outlet refills these units in about an hour on fast charge. The tow vehicle's 12V outlet or a DC input trickles it back while you drive. A fold-out solar panel tops it off when you are parked off-grid, which is the whole point; see the best portable solar panels and confirm your unit's maximum solar input before buying a big array.
Solar generator or a mounted RV solar kit: which should I buy?. A solar generator is a portable all-in-one you can carry between the rig, the campsite, and home, with no drilling. A mounted RV solar kit bolts panels to the roof to charge your existing 12V house bank whenever you are parked in sun. Many RVers run both: a rooftop array to keep the house batteries full and a solar generator for 120V appliances and portable power. The trade-offs for a camper are laid out in solar panels for RVs.
Does it have to be a LiFePO4 unit?. For an RV, yes, buy LiFePO4. Lithium iron phosphate cells last 3,000 to 4,000-plus cycles versus a few hundred for older lithium-ion, and they tolerate the heat of a parked rig far better, which matters when the unit lives in a hot storage bay all summer. Every pick above is LiFePO4. The chemistry differences are spelled out in LiFePO4 vs lithium-ion.
How we picked
These picks are research-based, drawn from manufacturer specs and owner feedback, not bench-tested in our own lab. Capacity, inverter output, and port layout change between model revisions, so confirm the watt-hours, the AC wattage, and whether a 30A RV outlet is included on the live listing before you buy.

Frequently asked questions
Can you run an RV off a solar generator?
Yes, for most of what you use. A solar generator easily powers the 12V-style loads (fridge, lights, fans, the water pump) and 120V devices like laptops, a coffee maker, and phone chargers, then recharges from shore power, the tow vehicle, or a fold-out panel. The one thing that separates units is a rooftop air conditioner, which only the bigger models can start and only for short runs. It is not a permanent replacement for shore power, but it covers most dry-camping needs.
What size solar generator do I need for my RV?
Weekend campers running lights, fans, a 12V fridge, and devices do fine on 500Wh to 1,000Wh. Full-timers with a residential fridge want 1,500Wh to 2,000Wh so they recharge less often, and running an air conditioner pushes you to 2,000Wh or more plus solar to refill it. Add up your watts times hours and check the total with the solar panel calculator.
Will a 2,000 watt solar generator run a refrigerator?
Yes, easily. A 12V RV fridge draws well under 100W, and a residential RV fridge runs around 100W to 200W with a brief startup surge that a 2,000W inverter absorbs without trouble. The limit is runtime, not wattage: a fridge cycling on and off will run for many hours on a 2,000Wh unit. See how many watts a refrigerator uses for the exact math.
What is the best solar generator for an RV?
For most rigs the EcoFlow Delta 2 is the pick: 1,024Wh of LiFePO4 and an 1,800W output in a 27-pound case that recharges fast and takes 500W of solar. If your goal is running a rooftop air conditioner, step up to the Bluetti AC200L (2,048Wh, 2,400W, with a built-in 30A RV outlet). Van-lifers on a budget should look at the Anker SOLIX C1000.
Is there a federal tax credit for a solar generator?
No. The 30% federal residential solar tax credit (Section 25D) expired for systems placed in service after December 31, 2025, and it never covered RVs or portable power stations as home equipment anyway. Treat a solar generator as a straight purchase with no federal credit. See our disclaimer for how we handle incentive claims.
