The Growatt 100W and 200W solar panels are designed to charge portable power stations. To ensure optimal performance, the panel must be placed in direct sunlight, kept clean, and angled correctly. Always ensure the MC4 connectors are securely attached to your power station using the appropriate adapter cable.

Setup and operation
1. Unfolding: Unfold the solar panel completely on a flat surface.
2. Positioning: Place the panel in an area with direct sunlight. Ensure the front of the panel is facing the sun.
3. Connection: Connect the solar panel to your portable power station using the MC4 to XT60 cable. Ensure the connection is secure.
Performance optimization
Solar charging efficiency is highly dependent on environmental factors:
- Angle: For best results, keep the panel angled between 45° and 90° relative to the ground.
- Sunlight: Ensure the panel is perpendicular to the sun's rays.
- Shading: Avoid any shading on the panel surface, as even partial shade can significantly reduce power output.
- Temperature: High surface temperatures can reduce efficiency.
Important safety warnings
- Do not drop the solar panel.
- Do not bend the solar panel.
- Do not strike the panel with sharp or heavy objects.
- The junction box and connectors must not be immersed in water.
- Do not use corrosive liquids to clean the panel.
- The junction box should only be opened or disassembled by qualified personnel.

Frequently asked questions
Can I connect 100W and 200W panels together? While possible, it is generally not recommended as the power output will be limited to the lower-rated panel.
Can I connect panels in parallel? Yes, you can connect panels in parallel, but the total current must not exceed 12A.
Why is my power output low? Output is affected by light intensity, surface temperature, and shading. Ensure the panel is clean and positioned optimally.

Practical help
Common problems
Low power output
Ensure the panel is perpendicular to sunlight, avoid shading, and check for surface dirt or high temperatures.
Panel damage
Do not drop, bend, or strike the panel with sharp objects. Damage to the glass will render the panel unusable.
Before use
- Unfold the solar panel completely.
- Ensure the front of the panel is facing the sun.
- Check for any shading on the panel surface.
- Verify the MC4 connection to your portable power station.
- Ensure the panel is angled between 45° and 90°.
Specs in practice
- Voc (Open Circuit Voltage)
- The maximum voltage the panel produces when not connected to a load.
- Isc (Short Circuit Current)
- The maximum current the panel produces when the output is shorted.
Images and diagrams
- The panel should be angled between 45° and 90° relative to the ground for optimal sunlight absorption.
- Connect the panel to a portable power station using the MC4 to XT60 cable.
Model compatibility
- Compatible with portable power stations that support MC4 standards.
- Parallel connection is possible but limited to a maximum current of 12A.
