best solar generator for rv (2026)

I don't live in an RV full-time. But I've spent enough weekends out in mine over the last three years to figure out which solar setups actually work and which ones make you wish you'd brought the gas generator instead. This is the guide I wish someone had written for me when I started.

Here's the core truth about solar power in an RV: the math matters more than the marketing. You need to know what your rig actually pulls, how many hours you need to cover, and how much sun you're realistically going to get. Get that right and a solar generator transforms your RV life. Get it wrong and you've got a $2,000 paperweight that runs your lights for six hours before it quits.

how to pick the right size

Every RV is different but most of them pull power in the same basic pattern. Here's what typical RV loads look like:

Add up what you actually run. Most RVers without AC land between 1,200Wh and 2,500Wh per day. With AC running even for a couple of hours, you're looking at 4,000Wh+ per day.

The math is: daily usage + 30% buffer = minimum battery capacity. Then figure out how many hours of good sun you'll get (4-6 in most US locations most months) and size your solar panels so they can refill what you used each day.

our picks by size

Three picks, one for each size category. I'll tell you what each one actually does and who should buy it.

best overall: ecoflow delta 2 max

Capacity: 2,048Wh LiFePO4
AC output: 2,400W continuous, 3,100W with X-Boost
Solar input: 1,000W max
Charge time (wall): ~1 hour to 80%
Weight: ~51 lbs
Price: ~$1,900 (unit) or ~$2,700 with 400W panels

This is the one I'd buy for 90% of RVers. It has enough capacity for most off-grid weekends, enough inverter output to run almost anything short of a rooftop AC continuously, and the solar input is high enough to actually refill the battery in a reasonable amount of time.

What I like:

• LiFePO4 chemistry means 3,000+ cycles to 80% capacity. That's 8+ years of heavy daily use.
• X-Boost lets it handle tools and high-surge loads that other 2,400W inverters reject.
• Expandable with an extra battery if you outgrow it.
• 1,000W solar input is excellent at this price point.
• Charges fast from shore power. Plug it in at the dump station for 30 minutes and top it off.

What I don't love:

• It's heavy. 51 pounds is a lot to move around inside an RV.
• The fan gets loud under high load. Not a dealbreaker but noticeable.
• Won't reliably run a rooftop AC for more than a short burst.

best for running ac: ecoflow delta pro

Capacity: 3,600Wh LiFePO4 (expandable to 25kWh)
AC output: 3,600W continuous, 4,500W with X-Boost
Solar input: 1,600W max
Weight: ~99 lbs (with wheels)
Price: ~$3,200 (unit) or ~$4,299 with 400W panels

The only unit on this list that reliably runs an RV rooftop AC for a meaningful amount of time. I've run my 13,500 BTU AC off a Delta Pro for nearly 2 hours on a single charge. That's not forever, but it's enough to get through the hottest part of the afternoon without cranking up the onboard propane generator.

The Delta Pro is also the right pick if you're in a larger Class A or toy hauler with higher daily power needs, or if you plan to boondock for more than a weekend at a time.

What I like:

• 3,600Wh is enough capacity to run a normal RV setup for 2-3 days without AC.
• 3,600W inverter handles rooftop AC, microwaves, electric kettles, induction cooktops.
• Expandable to 25,000Wh with extra batteries if you go all-in.
• Wheels make it manageable despite the weight.
• 1,600W solar input is the highest in this category.

What I don't love:

• 99 pounds. You're not carrying this in and out of the RV casually.
• Expensive. $3,000+ before panels.
• Overkill for anyone who doesn't run AC or large appliances.

best value: bluetti ac200l

Capacity: 2,048Wh LiFePO4
AC output: 2,400W continuous, 3,600W with Power Lifting
Solar input: 1,200W max
Weight: ~62 lbs
Price: ~$1,700 (unit) or ~$2,400 with 350W panels

If you want capacity close to the Delta 2 Max but want to save a few hundred bucks, the AC200L is a legitimate alternative. Same 2,048Wh capacity, similar output, slightly higher solar input, cheaper price. Bluetti's build quality has gotten significantly better in the last two years and the LiFePO4 cells in this unit are solid.

What I like:

• Best price-to-capacity ratio in this list.
• 1,200W solar input beats the Delta 2 Max at a lower price.
• LiFePO4 chemistry with 3,500+ cycles rated to 80%.
• Expandable with B300 batteries if you need more capacity.

What I don't love:

• Heavier than the Delta 2 Max (62 lbs vs 51 lbs).
• App is less polished than EcoFlow's.
• Power Lifting mode works but is less refined than EcoFlow's X-Boost.

what about smaller units?

A lot of RVers ask me about smaller solar generators like the Jackery Explorer 1000 Plus (1,264Wh) or the EcoFlow River 2 Pro (768Wh). Here's my honest take:

They work for weekend warriors with light power needs. If you're in a small travel trailer or van with a 12V fridge, LED lights, and some device charging, 1,000Wh will get you through a weekend. I won't tell you not to buy one.

But the problem with smaller units is the ceiling. The moment you want to run anything beyond the basics — a microwave, a coffee maker, a small space heater, a CPAP with a humidifier — you're hitting the inverter limit or burning through the battery in a few hours. Buying a 1,000Wh unit today means buying a 2,000Wh unit in 18 months when you get tired of managing your watt budget.

My recommendation: skip the small units unless your needs are genuinely small. The extra $500 to $700 for a 2,000Wh unit is the best money you'll spend on backup power.

mounting and storage

Two practical things nobody mentions in solar generator reviews:

Where it lives in the RV. A 50+ pound battery box needs a secure home. I keep mine strapped in a lower cabinet where it can't shift in transit and where the ventilation vents at the top aren't blocked. Pass-through storage in a fifth wheel or travel trailer works if you can protect it from dust and temperature extremes. Don't put it under the bed where airflow is zero.

Panels on the road. Portable panels are the easiest for beginners. Unfold them outside the rig, angle at the sun, plug in. The downside is you have to set them up every stop. If you're staying in one place for days, fine. If you're moving every morning, the setup gets old fast.

The alternative is roof-mounted panels wired directly to the solar generator through an MC4 adapter. That's more expensive and requires drilling into your roof, but it means the battery charges while you drive and while you're parked without any setup. A lot of serious RVers end up doing both — a small permanent roof array plus portable panels for when you need more.

what i'd buy in each situation

• Weekend camper, small travel trailer, no AC needed — Bluetti AC200L with 350W panels. Good capacity, best price.
• Full-time RVer, medium rig, no rooftop AC on solar — EcoFlow Delta 2 Max with 400W panels. Best balance of features and capacity.
• Class A, toy hauler, or anyone who wants to run AC for a few hours daily — EcoFlow Delta Pro with 400W panels, possibly expanded with a second battery. The only unit that handles rooftop AC reliably.
• Van life, stealth camping, weight and size matter — EcoFlow Delta 2 (1,024Wh) or Bluetti AC180 (1,152Wh). These are the right size for a van setup where every inch and every pound counts.
