In large-scale utility PV applications, Sungrow's 1+X Modular Inverter can assist with its intelligent branch diagnosis function, particularly beneficial when a system solution does not contain a combiner box or if the combiner box lacks communication capabilities. This innovative solution accurately identifies faulty branches within the inverter, providing real-time alerts for timely Operation and Maintenance (O&M). This proactive monitoring minimizes power plant losses and maximizes the customer's profitability.

By collecting current and voltage parameters from each branch of the DC inputs, the 1+X Modular Inverter uses AI algorithms to analyze the operational status of each branch. In the event of a fault, it promptly signals the monitoring system, notifying the O&M staff to take necessary measures.

Key advantages

1. More Accurate Diagnosis: The 1+X Modular Inverter leverages a vast database compiled from real-world data across various industries and time periods. This, coupled with factors such as inverter output power, ensures highly accurate diagnostic results.

2. More Diagnostic Types: The 1+X Modular Inverter can diagnose the combiner box offline, and the PV string offline, offering a comprehensive diagnostic solution for enhanced system reliability.

Sungrow’s commitment to technological innovation is evident in the 1+X Modular Inverter, providing users with a sophisticated tool to optimize performance, reduce downtime, and ultimately elevate the returns on investment for stakeholders of utility-scale PV installations. Sungrow stated in its semi-annual report that the Company has contracted a total of 16 GW of orders for its 1+X Modular Inverter globally, which is a testament to its success and credibility.
