Manufactured Solar Controller by Heargrow	Others
Fully adopting surface mount technology (SMT) on both sides of the board	Using through-hole technology (THT) on a single-sided board
Advantages: Fully Adopting Surface Mount Technology (SMT): Utilizing SMT for all components ensures high precision in component placement, which contributes to fewer faults and enhanced reliability of the assembled boards. High Component Accuracy and Lower Failure Rate: The precision afforded by SMT leads to higher accuracy in component mounting, reducing the likelihood of defects and failures. Double-Sided Boards with Increased Copper Content: Double-sided boards contain twice the amount of copper compared to single-sided boards, offering better heat dissipation and improved electrical conductivity. This also facilitates superior circuit connections and can support more complex designs.
Using industrial standard indicator light spacers	Using heat shrink tubing
Advantages: Industrial Standard Indicator Light Spacers: The use of industrial standard spacers for indicator lights ensures that the lights are properly aligned and stand upright, providing a professional appearance and better contact with the enclosure. Dual Lead Protection: Both leads of the indicator light are protected, unlike competitors’ products that use heat shrink tubing and can only protect one lead. This dual protection increases durability and reliability. Superior Stability and Contact: The design allows for superior stability, ensuring the indicator light does not easily become misaligned or (tilted). It maintains good contact with the outer casing, enhancing electrical connection and performance.
Using surface mount tantalum capacitors	Using through-hole electrolytic capacitors
Advantage: Using Surface Mount Tantalum Capacitors: While the cost is higher, these capacitors offer excellent stability. The superior performance and reliability of surface mount tantalum capacitors make them a valuable choice for applications where stability and quality are critical.
Using sector-shaped heat sink	Using standard heat sink
Advantage: Using Fan-shaped Heat Sink: The fan-shaped design of the heat sink offers superior heat dissipation, allowing the device to operate effectively even in extremely hot environments. This design enhances cooling efficiency, ensuring reliable performance under high-temperature conditions.

Determining Whether Load Equipment is Overloaded

Determining whether load equipment is overloaded is crucial for ensuring system safety and extending the lifespan of the equipment. Below are several common methods and steps to identify if your load equipment is overloaded:

1. Check Solar Controller Equipment Performance

• Performance Degradation: If the equipment’s operational speed slows down, output power decreases, or intermittent failures occur, these could be signs of overload.
• Abnormal Heating: Overloaded equipment generates excessive heat due to overcurrent, causing the surface temperature of the device to rise. This can be detected by touch or using an infrared thermometer.

2. Check Electrical Parameters

• Current Measurement: Use a clamp meter or other current measuring tools to directly measure the working current of the load equipment. Compare the measured value with the rated current on the equipment’s nameplate. If the actual current exceeds the rated current, it indicates possible overload.
  • For three-phase equipment, also check if the currents in each phase are balanced. Unbalanced current distribution can also indicate an overload problem.
• Voltage Measurement: Monitor whether the input voltage is below the normal range. Overload can cause voltage drops, affecting equipment performance.
• Power Factor Analysis: In some cases, analyzing changes in the power factor (PF) can help identify overload conditions. A lower power factor typically means there is more reactive power in the system, which could be due to excessive load.

3. Examine Protective Device Actions

• Circuit Breaker Tripping: If the circuit breaker frequently trips, especially multiple times within a short period, this is usually a clear sign of overload.
• Fuse Blowing: In older systems, blown fuses are a common indication of overload.
• Overload Protector Activation: Many modern devices have built-in overload protection features. When overload is detected, these protectors automatically cut off power to prevent damage.

4. Monitor System Alarms

• Smart Controller Alarms: Advanced power management systems or controllers can monitor load status in real-time and issue warnings or alarms when overload is detected. Detailed alarm information can be obtained by checking the controller display or connecting to monitoring software.
• Remote Monitoring Systems: For large facilities, remote monitoring systems (such as SCADA) can be used to monitor the status of critical equipment in real-time, promptly detecting overload conditions.

5. Analyze Historical Data

• Record and Analyze Operational Data: Regularly record operational parameters (such as current, voltage, temperature, etc.) and perform trend analysis. If you notice a parameter continuously rising over a certain period, it may indicate impending overload.

6. Professional Diagnostic Tools

• Thermal Imaging Camera: Use thermal imaging technology to scan the equipment comprehensively, quickly identifying hot spots that can help detect potential overload issues.
• Power Quality Analyzer: Used to analyze power quality issues in the grid, including harmonic distortion and voltage fluctuations, which can sometimes be related to overload.

Response Measures

Once overload is confirmed, immediate actions should be taken:

• Reduce Load: Turn off unnecessary equipment or redistribute the load.
• Upgrade Equipment Capacity: If frequent overloads occur, consider replacing the equipment with higher capacity models or adding redundancy.
• Optimize System Design: Improve circuit layout or adjust power supply schemes to enhance overall efficiency.

By following these methods, you can effectively identify and address overload issues in load equipment, ensuring the safe and stable operation of the system. If you have more specific situations or need further assistance, feel free to ask.
