Safety Precautions

Read all instructions before installation. Solar panels generate DC electricity when exposed to light.

Work during low-light conditions or cover panels to reduce electrical hazard.
Use insulated tools and wear appropriate PPE (gloves, safety glasses).
Ensure mounting surface is structurally sound and can support panel weight and wind loads.
Follow local electrical codes and obtain permits if required.

WARNING! Risk of electric shock. Disconnect all power sources before making connections. Panels are live when exposed to sunlight.

Installation Planning

Proper planning ensures optimal performance and safety.

Site Selection: Choose a location with maximum sun exposure (south-facing in Northern Hemisphere).
Shading Analysis: Avoid shadows from trees, chimneys, or other obstructions.
Roof Inspection: Check roof condition and integrity. Consult a professional if unsure.
Layout Planning: Arrange panels to fit available space, allowing for airflow and maintenance access.

CAUTION! Do not install during inclement weather. Ensure stable footing when working at heights.

Mounting the Solar Panels

Follow these steps to securely mount the solar panels.

Assemble Rails: Attach mounting rails according to layout, ensuring level alignment.
Attach to Surface: Secure rails to roof or ground mounts using provided lag bolts and seals.
Install Panels: Place panels on rails and secure with end clamps and mid-clamps.
Grounding: Connect grounding lugs to rails and run grounding wire to system ground point.

Tip: Do not overtighten clamps. Leave a small gap for thermal expansion.

Electrical Connections

Connect panels, controller, and batteries in correct order.

Panel Wiring: Connect panels in series or parallel per kit instructions using MC4 connectors.
Controller Connection: Connect PV input wires to charge controller, observing polarity (+/-).
Battery Connection: Connect controller to battery bank using provided cables.
Load Connection: Connect DC loads to controller load terminals if supported.

WARNING! Reverse polarity can damage equipment. Double-check all connections before applying power.

System Setup & Configuration

Configure the charge controller for your battery type.

Power On: Expose panels to light; controller display should activate.
Battery Type: Set controller to match battery chemistry (Flooded, AGM, Gel, Lithium).
Charge Parameters: Adjust voltage set points if necessary (defaults are usually optimal).
Load Settings: Configure timer or low-voltage disconnect for DC loads.

Note: Refer to controller manual for detailed menu navigation.

Operation & Monitoring

Monitor system performance regularly.

Controller Display: Shows PV voltage, battery voltage, charge current, and load status.
Performance Check: Ensure panels are clean and producing expected power during peak sun.
Battery Health: Monitor battery voltage to prevent over-discharge.

Tip: Log performance data to detect issues early.

Maintenance Guidelines

Regular maintenance ensures long-term reliability.

Panel Cleaning: Clean glass surface with water and soft cloth every 3-6 months.
Connection Check: Inspect and tighten connections annually.
Mounting Inspection: Check rails and clamps for corrosion or loosening.
Battery Maintenance: Follow battery manufacturer guidelines for watering (if flooded).

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

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power output	Shading, dirty panels, blown fuse	Clean panels, check for obstructions, inspect fuses.
Low charge current	Poor sun, incorrect wiring, faulty controller	Verify sun exposure, check series/parallel wiring, test controller.
Battery not charging	Wrong battery type setting, low voltage	Reconfigure controller, charge battery with alternate source.
Controller display off	No PV input, dead battery, loose connection	Check PV connections, battery voltage, and wiring.
Overheating components	Poor ventilation, overloading	Ensure airflow, verify load is within controller rating.

Reset: Consult controller manual for factory reset procedure.
