Renogy 220W / 400W Lightweight Portable Solar Panel Suitcase

The Renogy Lightweight Portable Solar Panel Suitcase is a foldable, kickstand-supported solar panel designed for overlanders, van dwellers, RV travelers, and off-grid cabin users who need deployable solar power without a permanent roof mount. The 400W variant weighs 30.2 lbs and folds to 27.9 × 33.7 × 3.2 in for transport; the 220W variant is lighter still at 15.87 lbs. Both variants use monocrystalline cells with ETFE coating and fiberglass reinforcement, and connect via IP68-rated solar connectors. A charge controller is required and sold separately.

Ready in One Minute, Built for Years of Field Use

The suitcase format means setup is a matter of unfolding the panel, extending the aluminum kickstands, and plugging in. No tools, no roof work, no drilling. For an overlander who moves camp daily or a van traveler who parks in shifting sun, that speed matters: the panel goes from packed to producing without eating into the day. The rust-resistant aluminum kickstands hold the panel at a fixed angle for consistent output and fold flat against the panel for transport, so nothing rattles loose on rough roads.

ETFE Coating and Fiberglass Reinforcement for Harsh Conditions

The panel surface uses an ETFE (ethylene tetrafluoroethylene) coating rather than standard glass, which reduces weight while maintaining weather resistance. The fiberglass-reinforced frame adds structural rigidity and resistance to light hail and trail debris. Corner protection guards the most impact-prone edges during loading and unloading. The panel carries a protection rating of ≥IP67, meaning it is rated to resist dust ingress and temporary water immersion; the solar connectors themselves are rated IP68. Together these materials mean the panel can stay deployed through rain without being pulled. That is a real-world convenience on trips where weather changes fast.

Parallel Wiring for Consistent Output in Partial Shade

The 400W suitcase uses parallel wiring between its internal panel sections. In a series-wired panel, a shadow on one cell drags down output across the entire string; parallel wiring limits that effect so that a shadow on one section does not proportionally reduce the output of the others. For camp setups under trees or near a vehicle's shadow, this wiring approach sustains more usable power through the day than a single-string design would.

Features

• Monocrystalline cells: 400W variant rated at up to 23% cell efficiency
• ETFE coating: lightweight weather-resistant surface layer with enhanced durability over standard glass
• Fiberglass reinforcement: structural frame rated to withstand light hailstorms
• IP68 solar connectors / ≥IP67 panel protection: dust-tight and water-resistant for outdoor deployment
• Aluminum kickstands: rust-resistant, fold flat for transport, deploy without tools
• Parallel wiring (400W): limits shade-induced output loss across panel sections

Who This Is For and Isn't

This solar suitcase suits overlanders, van travelers, RV users, and off-grid cabin owners who need portable, ground-deployable solar power that sets up without tools and packs away quickly. The 400W variant is sized for meaningful daily charging of house batteries or compatible portable power stations; the 220W variant suits lighter loads or weight-sensitive setups. Both work as a supplement to an existing solar system, provided the PV input voltage stays below the charge controller's rated solar input voltage.

A charge controller is not included and is required for battery charging. The panel cannot connect directly to a battery without one. Pairing with a portable power station requires that the station's DC input voltage rating exceeds 48V; stations rated below that threshold are not compatible. Electrical specifications for the 220W variant are not fully confirmed.

Common Questions

Does this solar panel include a charge controller?

The Renogy Lightweight Portable Solar Panel Suitcase does not include a charge controller. A charge controller is required to regulate current between the panel and a battery bank. The panel ships with the solar panel itself, a user manual, and an eWarranty card only.

Can this panel connect directly to a portable power station?

The Renogy Lightweight Portable Solar Panel Suitcase can pair with a compatible portable power station for plug-and-play charging, but the power station's DC input voltage rating must exceed 48V. Stations rated below that threshold are not compatible with this panel's output voltage.

What battery types can this panel charge?

The Renogy 400W Portable Solar Panel Suitcase is compatible with 12V lithium-ion, sealed lead-acid, flooded lead-acid, and gel batteries when paired with an appropriate charge controller. The charge controller must be matched to the panel's output voltage and the battery bank's voltage.

Is this solar panel waterproof enough for rain?

The Renogy Lightweight Portable Solar Panel Suitcase carries a ≥IP67 panel protection rating, meaning it is rated for dust ingress resistance and temporary water immersion. The solar connectors are rated IP68. The ETFE coating and fiberglass reinforcement add further weather resistance, making the panel suitable for deployment in rain.

How does parallel wiring help in partial shade?

The 400W Renogy Portable Solar Panel Suitcase uses parallel wiring between its internal panel sections. In a parallel configuration, a shadow falling on one section does not drag down output from the remaining sections the way it would in a series-wired design, so the panel sustains more usable output when part of its surface is shaded.

Can this panel be added to an existing solar system on an RV or shed?

The Renogy Lightweight Portable Solar Panel Suitcase can supplement an existing solar system. When doing so, the panel's PV input voltage must remain lower than the charge controller's rated solar input voltage to avoid damaging the controller or reducing system performance.
