GoodWe solar inverters are widely known for their reliability and user-friendly interface. Understanding the information displayed on your GoodWe inverter helps you monitor the performance of your solar power system and ensure it’s functioning efficiently. In this guide, we’ll walk you through how to read the key features of a GoodWe solar inverter display and what the information means.
Step 1: Locate Your Inverter and Display
The display on your GoodWe solar inverter is typically located on the front of the unit. Depending on the model, the display may be an LCD screen or a series of LED indicators. Ensure the inverter is powered on to access the necessary information.
Step 2: Key Parameters on the GoodWe Inverter Display
When navigating your GoodWe inverter display, you’ll typically encounter the following information:
1. Power Output (Current Power):
• What It Shows: This shows the real-time power output of your solar system, usually in watts (W) or kilowatts (kW).
• What It Means: It tells you how much electricity your system is generating at that exact moment based on sunlight conditions. On sunny days, this value should be higher.
2. Daily Energy (Today’s Output):
• What It Shows: This is the total energy your solar system has produced so far for the day, measured in kilowatt-hours (kWh).
• What It Means: It gives you a sense of how much energy your system has generated throughout the day.
3. Total Energy (Cumulative Output):
• What It Shows: The total amount of energy your system has produced since installation, usually measured in megawatt-hours (MWh) or kilowatt-hours (kWh).
• What It Means: This value reflects the long-term productivity of your solar system.
4. Grid Voltage (V):
• What It Shows: The voltage of the grid connection, typically displayed in volts (V).
• What It Means: This indicates the current grid voltage level. Your inverter needs to match the grid voltage to ensure proper power feed into the system. If the voltage is too high or low, the inverter may temporarily shut down.
5. Frequency (Hz):
• What It Shows: The frequency of the electricity being produced, measured in Hertz (Hz).
• What It Means: The grid typically operates at 50 Hz in Australia. If the frequency is outside the accepted range, your inverter may not be able to feed power into the grid.
6. Temperature:
• What It Shows: The internal temperature of the inverter, measured in degrees Celsius.
• What It Means: The inverter’s temperature is crucial for efficiency. Excessively high temperatures could indicate a need for cooling or ventilation improvement. If the temperature exceeds safe limits, the inverter may automatically shut down to prevent damage.
Step 3: Understanding Error Messages
GoodWe inverters are designed to alert you if there’s an issue. Common error codes or indicators might include:
• Grid Fault: This indicates that there is an issue with the grid connection, such as unstable voltage or frequency.
• Overvoltage/Undervoltage: This happens when the grid voltage is too high or too low for safe operation.
• Overtemperature: The inverter’s internal temperature is too high, possibly due to inadequate ventilation or a hot environment.
• Isolation Fault: This could indicate a grounding issue within the solar panel array.
Step 4: Navigating the Display (For LCD Models)
GoodWe inverters with an LCD screen often have navigation buttons below the display to allow users to switch between different parameters:
• ESC/Back: Takes you back to the previous screen.
• Up/Down Arrows: Scroll through the various display pages that show different performance metrics.
• Enter: Confirms your selection or opens up more detailed information.
Step 5: Using the GoodWe Monitoring App (Optional)
If your GoodWe inverter is connected to Wi-Fi, you can access real-time data through the GoodWe SEMS Portal or GoodWe App:
• SEMS Portal: This platform provides more detailed insights into the inverter’s performance, including graphical representations of power generation over time.
• GoodWe App: The app allows you to track your solar energy system’s performance remotely. It shows all the key metrics such as daily output, total energy produced, and real-time power generation.
Conclusion
Reading your GoodWe solar inverter display is an easy and effective way to monitor the performance of your solar system and ensure everything is working correctly. By understanding the key information such as power output, energy production, and grid connection, you can optimise the efficiency of your system and address any issues promptly. For more detailed monitoring, consider using the GoodWe SEMS Portal or App, which provides additional features and insights into your solar power generation.
