Quick Answer
String inverters typically do not offer built-in monitoring capabilities, but some models can provide basic data such as production output, voltage and current readings, and fault notifications through a simple display or a web interface.
Limited Built-In Monitoring
Most string inverters come with a basic display that shows essential information like power output, voltage, and current. However, this display is usually limited and may not provide detailed insights into the system’s performance. Some string inverters might offer a web interface or a mobile app for remote monitoring, but these features are not standard and may require additional hardware or subscription fees.
Third-Party Monitoring Solutions
For more comprehensive monitoring capabilities, users often rely on third-party solutions that can connect to the string inverter through communication protocols like Modbus, BACnet, or IEC 61850. These solutions can provide real-time data on production output, energy yield, and system performance, as well as alerts and notifications for faults or anomalies. Some popular third-party monitoring platforms include Solar-Log, Reolink, and Sense.
Modbus Protocol for Monitoring
Modbus is a widely used communication protocol that enables string inverters to share data with external monitoring systems. By connecting to the string inverter’s Modbus port, users can access a variety of data points, including voltage, current, and power output. Modbus monitoring solutions can be integrated with other system components, such as weather stations and energy storage systems, to provide a comprehensive view of the solar array’s performance.
