What's Included
- (1) Yoshino SP200 200W solar panel
- (1) Standard MC4 solar connection cable
- (1) User Manual (this document)
Setup
- Unfold the Solar Panel: Carefully unfold the Yoshino SP200 solar panel completely on a flat, stable surface.
- Position for Sunlight: Place the solar panel in an area with direct sunlight, free from shadows.
- Adjust Kickstands: Utilize the three adjustable kickstands on the back of the panel to angle it directly towards the sun. Optimal angle is typically between 30-45 degrees from the ground, depending on your latitude and the time of day/year. Adjusting the angle maximizes energy harvesting.

Operating Instructions
- Connect to Power Station: Connect the MC4 connector from the solar panel to the solar input port of your compatible portable power station. The SP200 is designed for seamless compatibility with Yoshino B330, B660, B2000, and B4000 SST solid-state portable solar generators.
- Monitor Charging: Once connected, your power station should begin charging. Monitor the charging status on your power station's display.
- Optimize Performance: For best results, ensure the panel remains in direct sunlight throughout the charging process. Periodically adjust the angle of the panel as the sun moves across the sky to maintain optimal efficiency. The monocrystalline silicon solar cells offer a 23% efficiency rating for superior energy conversion.

Maintenance
- Cleaning: Regularly wipe the surface of the solar panels with a soft, damp cloth to remove dust, dirt, or debris. Avoid using abrasive cleaners or harsh chemicals that could damage the ETFE lamination.
- Inspection: Periodically inspect the panel and cables for any signs of damage, wear, or loose connections.
- 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 built-in handle grip makes it easy to transport and store.
The SP200 features enhanced durability with ETFE lamination for protection in harsh environments and an IP67 water-resistant rating. It is designed to operate in temperatures ranging from -10°C to 70°C (14°F to 158°F).

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output from panel. | Not enough sunlight; Panel is shaded; Loose connection; Damaged panel/cable. | Ensure panel is in direct sunlight; Remove any obstructions causing shade; Check all cable connections; Inspect panel and cable for visible damage. |
| Low power output. | Panel not optimally angled; Dirty panel surface; Partial shading; Overcast weather. | Adjust panel angle towards the sun; Clean panel surface; Ensure no partial shading; Output will naturally be lower in cloudy conditions. |
| Panel not recognized by power station. | Incorrect connection; Incompatible power station; Faulty cable. | Verify MC4 connection is secure and correct; Ensure your power station is compatible with MC4 solar input; Try a different MC4 cable if available. |
