Installation

Unpack and inspect all components. Choose a location with maximum sunlight exposure.

Mount Solar Panel: Use brackets to secure panel on roof, ground, or pole facing south (in Northern Hemisphere).
Connect to Charge Controller: Attach panel cables to controller's solar input terminals.
Connect Battery: Wire battery to controller's battery terminals, observing correct polarity.
Connect Load: Attach devices to controller's load terminals if applicable.
Secure Wiring: Use cable ties to organize and protect cables from damage.

WARNING! Install during daylight only with panel covered to avoid electric shock. Ensure all connections are tight and correct.

First-Time Setup

After installation, configure system for optimal performance.

Check Connections: Verify all wiring is correct and secure.
Position Panel: Adjust angle for best sun exposure (typically 30-45 degrees).
Power On: Uncover panel; charge controller LEDs should indicate charging.
Monitor Battery: Use multimeter to confirm battery voltage increases during daylight.
Test Load: Connect a small device to ensure power delivery.

CAUTION! Do not disconnect under load. Keep panel surface clean for maximum efficiency.

Settings: None adjustable; automatic operation based on battery voltage. Monitoring: Check LED status regularly. Load Control: Controller automatically disconnects load if battery voltage drops too low.

Connecting Devices

Connect compatible 12V DC devices to load terminals of charge controller.

Ensure system is off before connecting devices.
Match device voltage to system (12V DC).
Do not exceed controller's load rating (10A).
Use appropriate cables and fuses for high-current devices.

Tip: For AC devices, use a power inverter connected directly to battery terminals.

Operation Guidelines

Optimal performance requires proper positioning and maintenance.

Sunlight: Place panel where it receives direct sunlight for 6-8 hours daily.
Angle Adjustment: Change panel angle seasonally for best exposure.
Battery Health: Regularly check battery water levels (if applicable) and terminals.
Performance Monitoring: Observe controller LEDs; green indicates full charge.
Shading Avoidance: Keep panel free from shadows of trees or structures.

WARNING! Do not attempt to repair panel or controller; contact support for service.

Maintenance & Care

Regular maintenance ensures longevity and efficiency.

Cleaning: Wipe panel surface with damp cloth to remove dust, dirt, or snow.
Inspection: Check cables and connections monthly for corrosion or damage.
Battery: Maintain proper charge; avoid complete discharge.
Storage: If storing, cover panel and disconnect battery.

CAUTION! Do not use abrasive cleaners or high-pressure water on panel.

Regulatory Information

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power output	Poor sunlight, dirty panel, loose connections	Clean panel, check all connections, ensure full sun exposure.
Battery not charging	Wrong polarity, faulty battery, blown fuse	Verify wiring polarity, test battery, check/replace fuse.
Controller LED off	No solar input, disconnected battery	Check panel and battery connections; measure panel voltage.
Low voltage output	Shading, panel damage, undersized cables	Remove obstructions, inspect panel for cracks, use thicker cables.
Overheating	Poor ventilation, excessive load	Ensure airflow around controller; reduce connected load.

Reset: Disconnect and reconnect battery to reset controller.
