Installation

Unpack and inspect contents. Choose optimal location.

Select Site: Place in direct sunlight, avoid shading from objects.
Mount Panel: Use provided grommets to secure to roof, rack, or stand.
Orientation: Angle panel towards the sun (typically 15-45 degrees).
Connect Cables: Attach MC4 connectors to charge controller or battery.
Secure Wiring: Route cables safely to prevent damage.

WARNING! Do not install during rain or thunderstorms. Ensure mounting surface is stable.

First-Time Setup

Connect panel to system; verify operation.

Connect to Charge Controller: Attach panel's MC4 cables to controller's solar input.
Connect Battery: Link controller to 12V battery following polarity (+/-).
Check Connections: Ensure all connections are tight and corrosion-free.
Verify Output: Use multimeter to confirm open-circuit voltage (~17-18V).
Position for Sun: Adjust angle for maximum sunlight exposure.

CAUTION! Always connect battery before solar panel to avoid controller damage.

Controls and Connections

Panel has no active controls. All regulation via external charge controller.

Connections: MC4 output cables (red positive, black negative). Junction box contains bypass diodes.

Charge Controller Settings: Set to "12V" battery type. Configure absorption/float voltages per battery specs. Use PWM controller for basic systems.

Monitoring: Check controller LED indicators or display for charging status.

Connecting to Devices

Connect only through a suitable charge controller to protect battery.

To Battery: Always use charge controller between panel and battery.
To Load: Connect load to controller's load terminals or directly to battery.
Multiple Panels: Connect in parallel (same voltage) to increase current.
Disconnecting: Disconnect battery first, then solar panel.

Tip: Use 10-12 AWG solar cable for runs under 10 feet to minimize loss.

Operation & Performance

Performance depends on sunlight intensity, angle, and temperature.

Daily Output: Expect 25-40 Watt-hours per day (varies with location/season).
Monitoring: Check controller regularly for charging status.
Seasonal Adjustment: Tilt angle steeper in winter, shallower in summer.
Cleaning: Keep glass surface clean for maximum efficiency.
Shading: Avoid even partial shading—it drastically reduces output.

WARNING! Do not short-circuit the panel outputs. Do not disassemble junction box.

Safety Features

Integrated blocking diode prevents battery discharge at night. Weatherproof IP65 rating for outdoor use. Tempered glass resists hail impact. MC4 connectors are touch-safe.

Care & Maintenance

Inspect periodically. Clean glass with water and soft cloth; avoid abrasive materials.

CAUTION! Do not use harsh chemicals. Disconnect before cleaning. Check for cracks or delamination.

Regulatory Information

Troubleshooting

Symptom	Possible Cause	Corrective Action
No output voltage	Shading, bad connection, diode failure	Check sunlight; inspect cables/connectors; test diode in junction box.
Low charging current	Dirty panel, wrong angle, cloudy day	Clean panel; adjust tilt; verify weather conditions.
Battery not charging	Wrong controller settings, faulty battery	Verify controller configuration; test battery health.
Hot spot on panel	Cell damage or shading	Remove shading source; inspect for physical damage.
Water in junction box	Seal failure	Disconnect, dry thoroughly, reseal or replace box.

Reset: Disconnect and reconnect all cables in correct order.
