O&M Related Concerns
1. How is discrete rate calculated?
Answer:
Dispersion rate = standard deviation of string current/average value of string current * 100%.
2. Why the inverter is generating power normally but dispersion rate analysis is not available?
Analysis:
1. Make sure that the date selected is correct.
2. We only calculate the power generation data between 10:00am and 14:00pm, so if the inverter power-up time is earlier than 10:00am or later than 14:00pm, then the data of that day will not be involved in the calculation. Please check the discrete rate analysis in the corresponding time.
3. What is IV curve?
Answer:
Current-voltage curve -- the shape of the IV curve is to judge the quality of the Solar panel under test.
4. How to scan and check IV curve diagnosis?
Answer:
Go to O&M -- IV Curve Diagnosis -- Start Diagnosis, and fill in the task information.
You can check the task details when it's complete.
Report can be generated as well, as shown below:
5. Why are some alarm intervals shown as "1d24h" but not "2d" straightforward?
Analysis: If it's not reaching the complete 24 hours like 23h 55mins, it will be displayed as "24h" approximately. So in this case, when the alarm duration reaches another 24 hours for a whole day, it will become "2d" then.
