Installation

Unpack and inspect contents. Ensure all components are present and undamaged.

Mounting: Use provided mounting brackets on a stable, load-bearing surface (roof or ground).
Orientation: Position panel facing true south (northern hemisphere) at optimal tilt angle.
Electrical Connection: Connect MC4 connectors in series or parallel per system design.
Grounding: Attach grounding lug to frame and connect to earth ground.

WARNING! Panel is heavy and fragile; use proper lifting techniques and safety gear. Do not install in wet conditions.

First-Time Setup

After installation, verify electrical connections before exposing to sunlight.

Check polarity: Ensure positive and negative cables are correctly connected to charge controller/inverter.
Verify voltage: Use multimeter to confirm open-circuit voltage matches specifications.
System integration: Connect to compatible charge controller (MPPT recommended).
Monitor output: Confirm power generation via monitoring system or inverter display.

CAUTION! Cover panel with opaque material during wiring to prevent live voltage. Use insulated tools.

Controls and Settings

Panel has no active controls; performance is managed through connected system components.

System Integration: Connect to MPPT charge controller for optimal power point tracking. Configure inverter settings for grid-tie or off-grid operation.

Monitoring: Use compatible monitoring software (web or app) to track real-time power, voltage, current, and energy production. Alerts for performance drops or faults.

Connecting Devices

Series Connection: Connect positive of one panel to negative of next to increase voltage. Parallel Connection: Connect positives together and negatives together to increase current.

Turn off all system components before making connections.
Use MC4 compatible cables and tools for secure connections.
Install appropriate fuses/breakers for overcurrent protection.
Route cables neatly, avoiding sharp edges and direct sunlight exposure.

Tip: Label all cables for easy identification during maintenance or troubleshooting.

Monitoring & Maintenance

Regular monitoring ensures optimal performance and early fault detection.

Daily: Check monitoring system for consistent power output.
Monthly: Visually inspect for physical damage, dirt, or shading.
Seasonally: Adjust tilt angle if using adjustable mounting system.
Annually: Perform detailed inspection of connections, frame, and glass.
Data Logging: Review monthly and yearly energy production reports.

WARNING! Do not walk on panels. Perform maintenance during low-light conditions or cover panels.

Safety Features

Integrated bypass diodes minimize hot spots during partial shading. IP67 junction box provides water and dust ingress protection. Frame includes pre-drilled grounding holes for proper earthing.

Care & Cleaning

Clean only when necessary and during cool, overcast conditions.

Use soft brush or sponge with mild soap and water. Rinse with low-pressure water. Do not use abrasive materials, harsh chemicals, or high-pressure washers.

CAUTION! Never spray cold water on hot panels - thermal shock can cause glass breakage.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power output	Shading, dirty surface, disconnected cables	Remove shading objects, clean panel surface, check all connections.
Low power output	Partial shading, soiling, mismatch with other panels	Clean panel, ensure uniform orientation, check for damaged cells.
Hot spots on panel	Bypass diode failure, cell damage	Contact authorized service for diode replacement or panel repair.
Water in junction box	IP67 seal compromised	Disconnect from system, dry thoroughly, replace seal or entire box.
Cracked glass	Impact damage, thermal stress	Stop using immediately. Contact support for replacement.

Reset: Disconnect and reconnect cables if monitoring shows faults.
