4. Connecting to Battery or Power Station
Connect the charge controller to your battery or power station using the appropriate cable:
- For direct connection to a power station, use the 3-meter extension cable with MC4 connectors.
- For direct connection to a LiFePO4, AGM, Gel, or Lead-Acid battery, use the cable with crocodile clamps.
Ensure correct polarity when connecting to batteries (positive to positive, negative to negative).
Operating Instructions
Once set up, the solar panel will begin generating power. The charge controller manages the charging process and protects your battery from overcharging or deep discharge.
Charge Controller Operation
The 20A charge controller is compatible with Lead-Acid, Gel, Flooded, and Lithium batteries. The default setting is for Lithium batteries. Refer to the charge controller's specific manual for instructions on adjusting battery type settings if needed.
The display on the charge controller will show charging status, battery voltage, and current. Monitor these readings to ensure proper operation.
Maximizing Efficiency
The monocrystalline cells provide an impressive efficiency of 24%. To achieve maximum power output, ensure the panel is positioned directly facing the sun and is free from shadows or obstructions.

Maintenance
Regular maintenance ensures the longevity and efficiency of your solar panel set.
- Cleaning: Periodically clean the surface of the solar panel with a soft, damp cloth to remove dust, dirt, or debris. Avoid abrasive cleaners or harsh chemicals that could scratch the surface.
- Connections: Regularly inspect all cable connections (MC4, crocodile clamps, charge controller terminals) to ensure they are tight and free from corrosion. Loose connections can lead to power loss or damage.
- Storage: When not in use, fold the solar panel and store it in a dry, cool place, away from direct sunlight and extreme temperatures. The integrated bag provides convenient storage for cables.
- Physical Inspection: Check the panel for any physical damage, such as cracks, dents, or frayed cables. Do not use the panel if it is damaged.
