Ensuring Exceptional Performance and Customer Confidence

 

 

1. Troubleshooting AC Output Flickering: Causes and Solutions

One of the most common issues reported by users is intermittent flickering of the AC output indicator or unstable power supply. While such occurrences are rare, they can be triggered by various factors—most of which can be easily resolved with proper usage.

✅ Common Causes:

• Overload or Inrush Current: Devices like refrigerators, compressors, or power tools can generate surge currents that exceed their rated power during startup.
• Incompatible Load Types: Certain motor-driven or inductive loads can create electromagnetic interference, affecting system stability.
• Low Battery Voltage: When the battery level drops below 20%, the device may trigger a protection mechanism, leading to automatic shutdown or output fluctuations.

🔧 Recommended Solution – “AC Reset Procedure”:

1. Completely power off the device using the main power button.
2. Disconnect all connected AC, DC, and USB devices.
3. Fully charge the device to 100% using the original charger or solar panel.
4. After charging, let it sit for 10 minutes.
5. Press the power button to restart the system.
6. Gradually reconnect devices, ensuring the total load does not exceed the rated power.

💡 Practical Tip: Always verify the continuous and peak power requirements of the appliances you are using. For compressor-type refrigerators, consider adding a soft starter to reduce inrush current.

⚠️ If the issue persists after following these steps, please prepare diagnostic materials and contact our technical support team.

2. Understanding Output Specifications and Interface Capabilities

To ensure safe and efficient use of FlashFish products, it is essential to understand their multi-port output architecture. Below is a general parameter table based on our popular model, the FlashFish E200:

Output Type	Voltage/Current	Max Power	Notes
AC Outlet (AC)	230V ~ 50Hz	200W (Peak 250W)	Modified sine wave output; overload protection included
DC5521 Interface	12V / 10A (max per port)	120W per port	Suitable for car refrigerators, lighting devices
USB-A Interface	2x USB Output QC3.0 (5V/2.4A + 9V/2A + 12V/1.5A) <br> 1 x USB Output 5V/2.4A	Up to 18W	Supports fast charging for phones/tablets
Car Cigarette Lighter	12V / 10A	120W	Compatible with car accessories

🔋 Important Note: All output ports can operate simultaneously within the battery capacity and inverter rating. If the total load exceeds the limit, the system will automatically cut off power.

⚠️ Warning: Do not connect multiple high-power devices in series without calculation. It is advisable to use the built-in LCD display to monitor input/output power and remaining usage time to avoid unexpected power outages.

3. Complete Charge and Discharge Cycle Recovery Process (Battery Calibration)

Lithium-ion batteries require regular complete charge and discharge cycles to calibrate the state of charge (SoC), improve runtime prediction accuracy, and extend overall lifespan. Under normal usage conditions, FlashFish recommends performing a complete charge and discharge calibration every three months.

🔄 Detailed Steps:

1. Fully discharge the device until it automatically shuts down (all indicator lights off).
   • It is advisable to keep a small load (e.g., an LED light connected via USB) to prevent the device from entering deep sleep mode.
   • Do not leave the device in a fully discharged state for more than 72 hours.
2. Charge continuously to 100% using the original AC adapter or solar array.
   • Do not use the device while charging during this process.
   • Typical charging time: approximately 4–5 hours for the E200 (using the charger).
3. After charging, let it sit for 30 minutes to allow the battery management system (BMS) to complete voltage balancing and stabilization, enhancing accuracy for subsequent use.
4. Verify display accuracy by observing whether the percentage matches actual performance. A calibrated system can significantly improve issues like "false drop in battery level" or "low battery misjudgment."

📌 Additional Note: This process helps resolve typical issues such as:

• Sudden drops in battery percentage or unexpected shutdowns
• Discrepancies between displayed remaining time and actual measurements
• Frequent restarts or inability to power on at low battery thresholds

4. Fault Reporting Material Submission Requirements: Video and Production Code Guidelines

If you have followed the troubleshooting steps but still experience issues, you will need to submit valid evidence for our technical support team to assess. To expedite the review process and avoid delays, please adhere strictly to the following submission guidelines:

🎥 Fault Video Must Include (Duration: 60–90 seconds):

• A close-up of the device screen clearly showing error messages or abnormal states.
• A demonstration of the actual problem (e.g., inability to start, AC light flickering, unresponsive buttons).
• A panoramic view of all connected cables and external devices (to rule out external faults).
• The process of restarting or charging attempts as per the manual.
• A clear shot of the product's back or bottom label (including model and serial number).

🔢 Required Information:

• Production code example format: QSFJ2409T300Pr0050
• Purchase date and retailer name
• Purchase order number

📌 Submission Method:

Please send all materials to our official email: info@flashfishtech.com.
Use the following subject format:
[Support Request] – [Model Name] – [Serial Number]

📁 File Upload Recommendations:

• Video files should preferably be in MP4 format as attachments.
• If the file is large, you may provide a download link via Google Drive or WeTransfer.
• ❌ Do not post sensitive information on social media or public platforms.
