Solar Gear On Your RV?
Nice.
Whether it came from the factory, a previous owner, or your own DIY hustle, we’re here to take it to the next level. At Great Outdoors Solar, we specialize in RV solar installations and flexible RV electrical upgrades that work with what you’ve got—not against it. Need a better inverter? More solar panels? A serious RV battery upgrade? We’ve got you. These services are perfect for travel trailers, fifth wheels, toy haulers, and motorhomes that just need a boost—not a full-blown overhaul.

Inverter-Only Installation
Power your RV appliances—even when you’re nowhere near a plug.
Looking to run your microwave, coffee maker, or RV AC while off-grid? An inverter transforms 12V DC battery power into the 120V AC power your RV appliances need. This install is perfect if you want to avoid firing up your generator every time you want toast. Whether you’re connecting to an existing solar setup or just want more freedom on RV travel days, we’ll install the right inverter to match your system, your goals, and your gear.
Solar Panel(s) - Only Installation
More solar = more freedom.
Sometimes your RV just needs a little more sunshine. Whether you’re replacing older panels, adding to your current RV solar array, or working around a tricky RV roof layout, we’ll help you find the right setup to keep your batteries charged and your adventure rolling. We match panel size and wattage to your RV’s available roof space—so you get the most power without wasting a single inch.


Battery Bank - Only Installation
Ditch the old batteries and upgrade your off-grid game.
If you’re still running lead acid batteries, you’re missing out. Upgrading to lithium means more usable power, less weight, faster charging, and no maintenance headaches. These smart batteries protect themselves, take up less space, and last way longer. Whether you're expanding an existing bank or starting fresh, we’ll design a setup that works for your RV’s layout, your energy needs, and your travel style.
Still not sure if lithium is worth it? Keep scrolling—there’s a quick comparison chart that breaks it all down.
Lithium batteries have built-in management systems which they utilize to protect themselves from damage, and require zero user maintenance. Upgrading and/or expanding your batteries is the best way to get more power from your RV.

Disclaimer
We try to keep it simple, but RVs love surprises.
Our prices cover typical installations—but let’s face it, no two rigs are exactly alike. If your RV needs extra materials, wiring, or time to get things done right, we’ll let you know as early as possible. We aim to catch everything up front, but if your RV throws us a curveball mid-install, we’ll keep you in the loop and work out a solution together.
