Sunjack SJ-PANL2-120W Quick Start Manual

The Sunjack SJ-PANL2-120W is a portable, foldable 120W solar panel designed for charging power stations, laptops, phones, and other USB devices. It features high-efficiency monocrystalline solar cells, a built-in kickstand, multiple output ports (USB-A, USB-C, DC), an integrated charge controller, and a durable, weather-resistant design. Below are key sections for safety, features, setup, operation, and troubleshooting.

Features at a Glance

Key components: Foldable solar panel array, Integrated kickstand, Charge controller with status LED, Output ports, Carrying handle.

Unpacking & Inspection

Unpack and inspect all contents. Ensure no damage occurred during shipping.

1. Open the box and remove the solar panel and all accessories.
2. Check contents: Solar Panel unit, user manual, warranty card, and any included cables (USB, DC).
3. Visually inspect the solar panel surface for cracks or defects. Inspect ports and the kickstand.
4. Unfold the panel fully to ensure hinges and fabric are intact.

WARNING! Do not use if the panel surface is broken or damaged, as this can pose an electrical hazard.

First-Time Setup

Position the panel and connect your device to begin charging.

1. Choose Location: Place the panel in direct sunlight, away from shade.
2. Unfold Panel: Lay the panel flat or use the kickstand to angle it towards the sun.
3. Connect Device: Using the appropriate cable, connect your device (power bank, phone, etc.) to one of the output ports.
4. Check Status: The status LED should illuminate, indicating power is being generated and transferred.
5. Monitor: Allow time for charging to begin. Actual charge rate depends on sunlight intensity.

CAUTION! Avoid pointing the lens of cameras or other optical devices at the reflective panel surface.

Controls and Ports

All user interfaces are located on the charge controller module or panel edge.

Controller Module: Contains all output ports and the status LED.

Status LED Indicators: Solid Green - Normal operation/charging. Blinking Green - Low sunlight or partial shade. Red/Blinking Red - Fault (overload, short circuit, over-temperature).

Output Ports: Clearly labeled USB-A, USB-C, and DC Output. Use manufacturer-recommended cables.

Kickstand: Flip out to adjust panel angle. Ensure it is fully locked in place before releasing the panel.

Connecting Devices

Connect compatible devices to the appropriate output port.

1. Ensure the panel is in sunlight.
2. Identify the correct cable for your device (USB-A to Micro-USB, USB-C to USB-C, DC to DC).
3. Plug the cable into the correct port on the solar panel's controller.
4. Connect the other end to your device.
5. The status LED will activate. Your device should indicate it is charging.

Tip: For fastest charging of a power station, use the DC output port with the correct cable. Charge phones directly via USB.

Charging Operation

Maximize efficiency by understanding charging behavior.

1. Sunlight is Fuel: Output power is directly dependent on sunlight intensity. Full sun yields maximum (or near maximum) output.
2. Partial Shade: Even slight shading on one cell can significantly reduce total output. Keep the entire panel surface in sun.
3. Device Compatibility: The panel auto-negotiates voltage/current with USB-C PD devices. For older USB-A devices, it provides standard 5V.
4. Simultaneous Use: You can typically charge multiple devices at once, but total output will be shared and may not exceed 120W.
5. Weather: The panel will still generate some power on cloudy days, but at a reduced rate.

WARNING! Do not attempt to disassemble the controller or panel. There are no user-serviceable parts inside.

Optimal Positioning

For best performance, angle the panel perpendicular to the sun's rays.

General Rule: Angle the panel so that sunlight hits it directly, not at a glancing angle. Use the kickstand to adjust.

Time of Day: Reposition the panel every few hours to follow the sun for all-day charging.

Clearing Obstructions: Ensure trees, buildings, or other objects do not cast shadows on the panel.

Care & Storage

Proper care extends the life of your solar panel.

1. Cleaning: Wipe the solar cell surface with a soft, damp cloth to remove dust, dirt, or bird droppings. Do not use abrasive cleaners.
2. Storage: Fold the panel neatly. Store in a cool, dry place away from direct sunlight when not in use for extended periods.
3. Transport: Ensure the panel is fully folded and secured before moving. Use the carrying handle.
4. Water Exposure: While splash-resistant, do not submerge the panel or controller in water. Dry thoroughly if it gets wet.

CAUTION! Do not place heavy objects on the panel or fold it with cables caught in the hinges.
