LensunSolar 400W Foldable Solar Panel

Unfold four 100W sections for a 400W rated portable solar setup at camp or beside your RV. The LensunSolar OP400W combines a folding format, kickstands and a listed 5m/16ft solar cable to help you position the panel in sunlight while keeping compatible equipment nearby.

Check Voltage Compatibility First

This panel's listed operating voltage is 48V and open-circuit voltage is 56.64V. Confirm your power station or charge controller accepts the panel's voltage and current, including the equipment manufacturer's required allowance for cold-weather voltage rise. It is not suitable for every portable power station.

An adapter changes the physical connection, not the panel's voltage. Do not assume that a matching XT60, Anderson or DC plug makes a device electrically compatible. For battery charging, use a suitable charge controller configured for the battery system; no controller is listed as included.

Portable Panel Features

• 400W rated peak power: Actual output depends on sunlight, shading, temperature, angle and connected equipment.
• Four-section folding format: Listed folded dimensions of 31.4 × 29.2 inches (797 × 741mm).
• Kickstands: Help position the panel toward sunlight, without a guaranteed percentage gain over flat placement.
• Supplier-described ETFE and multilayer lamination: Construction intended for portable outdoor solar use.
• Supplier-listed IP67 panel rating: Does not establish the rating of adapters, connectors or connected devices. Protect connections and follow the manufacturer's exposure instructions.

Listed Electrical Specifications

• Model: OP400W
• Rated peak power: 400W (4 × 100W sections)
• Optimum operating voltage (Vmp): 48V

Ratings are specified at standard test conditions: AM1.5, irradiance 1000W/m² and cell temperature 25°C. Field output and charging time vary.

Details to Confirm

The source lists cell efficiency as both 25% and 23.7%. Confirm the correct cell specification; neither figure establishes complete-panel efficiency. Weight is listed as 9.5kg in the feature copy and 9.55kg in the specifications, both approximately 21 lb. Confirm the exact net weight when planning transport.

The four-in-one adapter is described as Anderson, XT60, DC5521 and DC7956 in the feature copy, but the packing list instead names an unspecified 8mm DC connector. Verify exact connector dimensions, polarity and electrical ratings before ordering.

What's Included

• 1 x LensunSolar 400W foldable solar panel
• 1 x four-in-one adapter cable, with exact DC ends to confirm

A power station, battery and charge controller are not listed in the package contents. This panel does not store energy for use after sunset.
