3. Product Overview
3.1 Components
The ATEM POWER 300W Portable Foldable Solar Panel kit typically includes:
- 300W Foldable Solar Panel
- 20A MPPT Solar Charge Controller
- MC4 to Multi-connector Adapter Cable
- Battery Clamp Cable
- Carry Bag
3.2 Key Features
- HPBC Cell Technology: The panel utilizes HPBC (Heterojunction with Back Contact) cells, which relocate metal contacts to the rear. This design minimizes shading on the front surface, enhancing sunlight absorption and contributing to a high power conversion efficiency of 25.8%.
- Durable ETFE Coating: The panel features an anti-crack, flexible ETFE film. This coating provides strength, thermal stability, and resistance to physical stress, protecting the cells. It is corrosion-resistant, stain-proof, and has a self-cleaning, non-stick surface that improves light transmission.
- Integrated MPPT Charge Controller: The included 20A MPPT (Maximum Power Point Tracking) controller optimizes charging for 12V/24V batteries, including Lead Acid, AGM, GEL, Calcium, and LiFePO4 types. It also features USB-A (18W Max) and USB-C (60W Max) ports for charging small electronic devices.
- Portability: The 300W solar panel weighs approximately 7.8kg (17.2 lbs) and folds into a compact size of 500x610x75mm (19.68"x24"x2.95") for easy transport and storage. It includes a sturdy carry handle and hanging loops.
- Safety Protections: The system includes protection against reverse polarity, overcurrent, undervoltage, overvoltage, and short circuits.

4. Setup Instructions
4.1 Unfolding the Solar Panel
- Place the folded solar panel on a flat, stable surface.
- Carefully unfold the panel sections until it is fully extended.
- Position the panel to face the sun directly for optimal performance.
4.2 Connecting the MPPT Controller
The MPPT controller is typically integrated or connected via MC4 connectors. Ensure the controller is connected to the solar panel before connecting to a battery or power station.
4.3 Connecting to a Battery or Power Station
The solar panel system offers wide compatibility for various charging scenarios:
- For 12V/24V Batteries: Connect the MPPT controller's battery terminals to your 12V or 24V battery using the provided battery clamp cable. Ensure correct polarity (positive to positive, negative to negative).
- For Power Stations: Use the MC4 to multi-connector adapter cable to connect the solar panel directly to compatible portable power stations. The adapter typically includes various DC plugs (e.g., DC7909, DC5525, DC35135, DC5521, Anderson Plug, XT60).

4.4 Selecting Battery Type (MPPT Controller)
To ensure optimal charging and battery longevity, select the correct battery type on the MPPT controller:
- Locate the 'BATTERY TYPE' button on the MPPT controller.
- Press and hold the button until the indicator light begins to flash.
- Cycle through the battery types (Lead Acid, AGM, GEL, Calcium, LiFePO4) by short-pressing the button.
- Release the button when the desired battery type's indicator light is solid. The controller will save the setting.

5. Operating Instructions
5.1 Optimal Panel Placement
For maximum power generation, position the solar panel directly facing the sun. Adjust the angle periodically throughout the day to track the sun's movement. Avoid shaded areas, as even partial shading can significantly reduce output.

5.2 Monitoring Charging
The MPPT controller features indicator lights for solar input and load status. Refer to the controller's specific LED indicators to monitor charging activity and battery status.
5.3 USB Output Usage
Connect compatible USB devices (smartphones, tablets, etc.) to the USB-A or USB-C ports on the MPPT controller for direct charging. Ensure the solar panel is receiving sufficient sunlight for stable power output.
6. Maintenance
6.1 Cleaning the Solar Panel
The ETFE coating is designed to be self-cleaning. However, for optimal performance, periodically clean the panel surface with a soft, damp cloth to remove dust, dirt, or debris. Do not use abrasive cleaners or harsh chemicals.

6.2 Storage
When not in use, fold the solar panel and store it in its carry bag in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure all cables are neatly coiled to prevent damage.
7. Troubleshooting
If you encounter issues with your solar panel, refer to the following common troubleshooting steps:
- No Power Output:
- Ensure the panel is in direct sunlight and not shaded.
- Check all cable connections for tightness and correct polarity.
- Verify the battery type setting on the MPPT controller is correct.
- Inspect cables and connectors for any visible damage.
- Low Charging Current:
- Ensure the panel surface is clean and free of dirt or debris.
- Adjust the panel's angle to face the sun more directly.
- Check for partial shading from trees, buildings, or other objects.
- Consider ambient temperature; extreme heat can reduce panel efficiency.
- Controller Not Responding:
- Disconnect and reconnect all power sources (solar panel first, then battery).
- Ensure the battery voltage is within the controller's operating range.
