Coachmen Beyond 22RB: Portable Solar Panels Guide

Introduction: Embracing Off-Grid Freedom with the Coachmen Beyond 22RB

The Coachmen Beyond 22RB is a lightweight, travel-friendly Class B+ motorhome that has become a favorite among tiny living enthusiasts seeking both mobility and self-sufficiency. With its compact footprint and efficient layout, this rig is designed for off-grid adventures, but its true potential is unlocked with the right solar setup. This guide focuses specifically on portable solar panels for the 22RB, offering a practical path to reliable off-grid power.

Why Portable Solar Panels Are a Smart Choice for the Coachmen Beyond 22RB?

The Beyond 22RB comes with a modest factory-installed solar system, typically a single 190-watt rooftop panel and a 100-amp-hour battery. While this handles basic needs like LED lights and the fridge on propane, it falls short for running a microwave, coffee maker, or multiple device charges during cloudy days. Portable solar panels offer flexibility—you can position them in direct sunlight while parking in shade, tilt them for maximum absorption, and even use them outside the RV while boondocking. For a 22RB owner, adding portable panels can double or triple your solar capacity without major roof modifications.

What Portable Solar Panel Size and Wattage Works Best for the 22RB?

For the Coachmen Beyond 22RB, the sweet spot lies between 200 to 400 watts of portable solar capacity. Here’s a breakdown of recommended configurations:

A 200-watt panel paired with a portable power station (like a Jackery or EcoFlow) is a common starter setup for 22RB owners. If you have the factory solar already, a 300-400 watt portable array can complement it seamlessly, especially when you need extra juice for cloudy days.

How to Connect Portable Solar Panels to the Coachmen Beyond 22RB’s Electrical System?

Connecting portable panels to the 22RB is straightforward but requires careful planning. The rig has a standard Zamp solar port (SAE connector) on the exterior, but this is rated for around 200 watts max and often lacks proper overcurrent protection. For larger portable setups, consider these methods:

• Direct to battery via solar controller: Use a high-quality MPPT charge controller (e.g., Victron SmartSolar 100/30) wired directly to the house battery bank. This bypasses the factory port and handles up to 400 watts safely.
• Portable power station approach: Instead of wiring directly, charge a portable power station (like Bluetti AC180) via the solar panels, then plug the power station into the 22RB’s shore power inlet. This adds redundancy and easy relocation.
• Using the Zamp port with an adapter: If you keep it under 200 watts, an SAE-to-MC4 adapter cable works, but upgrade the factory fuse to 25 amps for safety.

Remember: Always use a solar controller between panels and batteries to prevent overcharging. Many portable panel kits now integrate controllers, simplifying installation.

Best Portable Solar Panel Brands for the 22RB: A Comparison

Not all portable panels are created equal, especially for the 22RB’s limited storage space and 12V system. Here are top contenders:

Renogy is a budget-friendly workhorse for the 22RB, while EcoFlow offers premium efficiency for heavy users. For owners prioritizing storage, the foldable Renogy or Jackery panels slide easily under the rear bed or in the over-cab storage of the 22RB.

What Are the Best Placement and Storage Tips for Portable Solar Panels on the 22RB?

Space is tight in the Beyond 22RB, but smart planning makes portable solar manageable. Here’s how to deploy and store panels:

• Deployment: Place panels on the sunny side of the RV, tilted 30–45 degrees toward the equator. Use stakes or sandbags to secure them in wind. The 22RB’s 6.5-foot height allows panels to clear the ground easily.
• Storage: Foldable panels fit in the 22RB’s rear pass-through storage (approx. 30 inches deep x 48 inches wide). For rigid panels, use the roof rack or a custom slide-out tray under the chassis—many 22RB owners install a DIY tray for 200W panels.
• Cable management: Run cables through a passenger-side window seal or use a dedicated port like the Zamp socket. Keep 10–15 feet of cable length for flexibility.

What Accessories Do You Need for a Complete 22RB Portable Solar Setup?

Beyond the panels themselves, these accessories improve performance and safety:

• Solar charge controller (if not built-in): MPPT controllers (e.g., Victron SmartSolar 100/30) boost efficiency by 20-30% over PWM for the 22RB’s 12V system.
• Battery monitor: A Victron BMV-712 or Renogy BT-2 lets you track state of charge accurately. The 22RB’s factory panel lacks this detail.
• Extension cables: 10 AWG MC4 cables (20-30 feet) for distances from panels to controller. Avoid SAE extensions due to voltage drop.
• Fuse or circuit breaker: 30A inline fuse between controller and battery for safety.
• Portable power station (optional): A 500-1000Wh unit (like Jackery Explorer 1000) simplifies connection and adds USB/AC outlets for the 22RB’s smaller loads.

What Owners Say About Portable Solar on Their 22RB

Owner feedback from forum posts and reviews highlights consistent trends. Many praise the ability to run a small electric cooler and laptop for 3-4 days with a 200W portable setup. One owner shared, “I pair a Renogy 200W suitcase with my 22RB’s factory battery, and it keeps my fridge on DC for two days without propane.” Another said, “The Jackery 3000 with two SolarSaga 200 panels fits under the dinette seat—perfect for staying power-out free during storms.”

Common complaints include wind blowing panels over and storage challenges for rigid panels. Most recommend foldable models and using the rear storage area. For bathroom upgrades related to off-grid living, see Coachmen Beyond 22RB: Best Composting Toilets for Tiny Bathrooms.

Frequently Asked Questions

Have more questions about portable solar for the Coachmen Beyond 22RB? Here are the six most common ones with answers from experienced owners:

• Can I use portable panels without modifying my 22RB? Yes. Simply connect to a portable power station or use the Zamp port with an adapter for up to 200 watts. No permanent changes needed.
• How long does it take to charge the 22RB’s battery with 200W portable panels? On a sunny day, a 100Ah battery (1,200Wh) can fully charge in 6-8 hours from a 200W panel at peak output. Cloudy days double or triple that time.
• Should I upgrade the factory solar controller if using portable panels? If you use the factory rooftop panel alongside portable panels, yes. The factory PWM controller may limit combined input. An MPPT controller handles both efficiently.
• Can I run a roof air conditioner with portable solar on the 22RB? Only with massive solar (800-1000W) and large battery bank (200Ah+ lithium). Most owners stick to 12V fans or small window units instead.
• What’s the weight limit for portable panels stored in the 22RB? The rear pass-through storage holds up to 150 pounds safely. Most 200W suitcase panels weigh under 40 pounds, so weight is rarely an issue.
• Do I need a special solar controller for lithium batteries in the 22RB? Yes. Many newer 22RB models come with lithium-ready converters, but portable panels still need a controller with a lithium profile. Victron and Renogy models support LiFePO4.
