Occasionally, we receive some calls to ask how to modify the energy yield. Although the energy yield is not a key parameter, many power plants need to be appraised every month. Therefore, the energy yield becomes a very critical data. In fact, if the inverter is running properly and the data is normal, the energy yield does not need to be changed. However, in many cases, the inverter has a certain failure rate. If a fault occurs occasionally, the energy yield changes greatly. In this case, you need to change the energy yield. Let me give you a brief introduction: First, log in to the SmartLogger. The method is described in the previous content. Log in to the SmartLogger as an advanced user or a special user. The password is Changeme. During maintenance, you can find the energy yield correction and change the energy yield.
