Features at a Glance

Key components: 120W Monocrystalline Solar Panel, Solar Charge Controller, DC Output Cables, USB Ports, Carrying Handle, Adjustable Kickstands.

Installation

Unpack and inspect contents. Ensure all parts are present.

1. Unfold the solar panel: Lay flat on ground or mount surface.
2. Adjust kickstands: Set desired angle (approx. 30-60°) facing direct sunlight.
3. Connect to charge controller: Use provided cables from panel to controller input.
4. Connect to battery/device: Use output cables from controller to battery/device.
5. Secure connections: Ensure all connectors are firmly attached and dry.

WARNING! Do not install near flammable materials. Keep panel surface clean and unobstructed. Avoid shading on cells.

First-Time Setup

Position panel in direct sunlight; follow connection sequence.

1. Connect panel to controller first (INPUT ports).
2. Connect controller to battery/device (OUTPUT ports). Observe polarity (+/-).
3. Check controller display: Should show battery voltage and charging status.
4. Adjust panel angle: Maximize sun exposure throughout the day.
5. Test outputs: Connect USB device to verify charging.

CAUTION! Never connect panel directly to battery without controller. Ensure battery voltage matches (12V).

Controls and Settings

Charge Controller Interface: LCD display shows battery voltage, charging current, and status icons.

Controller Buttons: MODE (cycle display), ON/OFF (enable/disable output).

Display Modes: Battery voltage (V), Charging current (A), Charging power (W), Charging status (bulk/float). Protections: Over-current (auto shut-off), short-circuit (auto recovery), reverse polarity (alarm), over-temperature (reduction). Settings: Low voltage disconnect (LVD) preset for 12V battery. No user password required.

Connecting Devices

Compatible with 12V batteries (lead-acid, LiFePO4), power stations, DC devices (fans, lights), USB devices.

1. Ensure panel is in sunlight and controller is off before connecting.
2. Connect to battery: Match red (+) to positive, black (-) to negative.
3. Connect USB devices: Plug directly into USB-A or USB-C ports.
4. Connect DC devices: Use appropriate adapter to 5521 DC output.

Tip: For best performance, use cables shorter than 10 feet and of adequate gauge.

Charging & Operation

Supports charging 12V batteries and powering USB/DC devices simultaneously.

1. Optimal placement: Face panel directly toward sun, adjust every 2-3 hours.
2. Monitoring: Check controller display for real-time voltage/current.
3. Charging stages: Bulk (constant current), Float (constant voltage).
4. USB charging: Devices draw current as needed (up to port max).
5. Disconnecting: Turn controller OFF, disconnect battery/device, then panel.
6. Storage: Fold panel, store in dry, cool place away from direct sun.

WARNING! Do not attempt to charge devices beyond specified voltage. Do not disassemble controller. Keep away from children.

Safety Features

Built-in Protections: Over-current, short-circuit, reverse polarity, over-temperature. Waterproof: Panel rated IP65 (controller is water-resistant only). Low Voltage Disconnect (LVD): Prevents battery over-discharge.

Care & Cleaning

Disconnect all cables before cleaning. Use soft, damp cloth to wipe panel surface. Do not use abrasive cleaners or high-pressure water.

CAUTION! Do not expose controller to heavy rain or submersion. Store in dry condition when not in use.
