inverter-based resources (IBR) and the response of state-of-the-art protection relays to the fault currents and voltages from GFM IBRs. Experts agree that GFM IBR dom nated systems will lead to significant impact on system protection schemes, particularly distance, directional, and power swing schemes. Expert interviews and the literature r
PDP-pro or PDP protection triggered when there is a fault signal or hardware overcurrent occurred to the driver board. Check if the AC and DC are short circuit and if the grid is abnormal. Record the PDP fault code from the HMI and contact SUNGROW. 6. Leakage current protection (I leakage-pro) Leakage current sampling value exceeds the set value.
Convert it into a voltage signal. Trigger protection and generate an alarm. As mentioned earlier, electrical fire caused by DC arcs is the most common safety accident with the greatest losses in PV systems, which seriously threatens the asset safety of owners. The key solution is to realize active and rapid shutdown in case of DC arcs.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
When detecting that the terminal temperature is high, the inverter enables the protection mecha-nism, generates an alarm, and reports the alarm to the app to prevent the fault from spreading.
