How to Perform a Test with the Seaward Solar Utility Pro

Ready to ensure your solar PV system is performing at its peak? Follow these straightforward steps to conduct a test with the Seaward Solar Utility Pro. It’s easier than you think, and the insights you’ll gain are invaluable.
Step 1: Connect Your Equipment

- Secure the Connection: Start by connecting the Solar Utility Pro to the PV module(s) or system using the supplied test leads. Ensure the connections are secure to prevent any inaccuracies in the readings.
Step 2: Power On and Initial Check
- Power Up: Turn on the Solar Utility Pro. Once you do, it will detect any DC voltage automatically, which is connected to the PV test socket inputs and show the voltage (Voc).
- Check Polarity: If you reverse the PV voltage polarity, there will be flash across next to the voltage icon on polarity indicator, alerting you to adjust the connection.
Step 3: Safety First
- Voltage Alert: If the voltage incoming is higher than 30V, the shock hazard icon will flash as a safety warning. Always ensure you’re taking the necessary precautions when handling high voltages.
Step 4: Conduct the Test

- Press the TEST Button: With everything connected and checked, press the TEST button. The Solar Utility Pro will automatically measure the short circuit current (Isc), providing you with accurate and crucial data about your system’s performance.
Step 5: Interpret the Results

- Understand Your Data: The device will display the results on its clear digital display. Use this data to assess the health and efficiency of your solar PV system. If you encounter any issues or unexpected readings, it may be time for a more thorough inspection or maintenance.
Step 6: Data Management

- Save and Analyze: Remember, the Solar Utility Pro can store up to 999 datasets. Make sure to save your results for future reference and analysis. This data is key to tracking the performance and health of your system over time.
Pro Tip: Always ensure the DC voltage polarity is correct and within the operational range (5V to 1500V) before initiating the test. If the voltage is outside this range or if the polarity is incorrect, the Test key will be disabled until the issue is resolved.
By following these steps, you’re not just conducting a routine check; you’re taking a proactive approach to maintaining the efficiency and longevity of your solar PV system. The Seaward Solar Utility Pro is your ally in this journey, providing the precision, reliability, and ease of use needed to keep your system running smoothly.
