String issues can be caused by poor connections within the string, or one or more Power Optimizers malfunctioning. . Learn how to troubleshoot and fix the SolarEdge V-String too high issue effectively. The SolarEdge inverter is designed to monitor the voltage of each string connected to it. If the voltage exceeds the manufacturer's specified limits, the inverter triggers a fault to protect itself and the entire. . It is causing my string inverter to shut down. Sometimes it goes up to 650volts and inverter shuts down. The key is to achieve a precise match with the rated input parameters of the inverter, while comprehensively considering system safety, power generation efficiency, and overall cost. . Excessive PV modules are connected in series in the PV string, and therefore the PV string open-circuit voltage exceeds the maximum operating voltage of the device.
