IV curve scanning is a technique used to measure the current (I) and voltage (V) characteristics of solar panels. . Therefore, for the conversion efficiency of the system, we need to check the status of the PV modules frequently to diagnose any issue in the very early stage. However, the photovoltaic panels are installed in open areas and are easily affected by the surrounding environment. You can use an I-V curve tracer as. . The results confirm that Huawei-developed Smart I-V Curve Diagnosis technology reaches Level 4 (L4 for short), according to the CGC/GF 180:2020 "Technical Specifications for PV String I-V Scanning and Smart Diagnosis Evaluation" and IEC 62446-1: 2016 "Photovoltaic (PV) systems - Part 1: Grid. . An IV curve represents the relationship between the current (I) and voltage (V) of a solar panel: Open Circuit Voltage (Voc): The maximum voltage available from a solar panel when no current is flowing. Short Circuit Current (Isc): The maximum current available when the terminals are shorted.

On the QR code scanning screen, align the QR code with the scanning box to automatically scan and connect to the WLAN of the inverter. The WLAN name of a product consists of "Device name-Product SN. ". Connect to the inverter WLAN. If you are unable to scan the barcode, you can insert the inverter connection. . You are advised to log in to the FusionSolar app to commission devices using method 1. Navigate to and open the Camera app, and make sure PHOTO is selected at the bottom.
