Specifically, the PV array’s monitoring system checks: Managed and unmanaged switches integrate and protect the network, while FL mGuard security devices provide firewall security and user management. The array is networked by Phoenix Contact’s Radioline wireless modules that communicate with PV module temperature and soiling sensors via RS-485, while its Power over Ethernet (PoE) devices transmit data and power at the same time.

Meanwhile, an industrial PC runs SCADA software that gathers data for history and long-term trending, and its Solarworx software manages solar power data and supports communications. For example, PV functions are managed by its PLCnext controller, which aggregate data from its I/O modules and EMpro meters, and transmit it to a cloud-computing service for analysis by the company or third-parties. Phoenix Contact also has more than 20 years of solar power experience, so its PV array also highlights its related products and services. To monitor and control its PV array, provide alerts, and collect and analyze data, Phoenix Contact’s facilities management team looked in-house to its own engineering services department. The array is integrated with the company’s building management system (BMS). Its I/O points gather information on the PV system’s inverters, cameras, string currents and voltage, PV module soiling, temperature and weather (Figure 1). Similar to any large distributed energy resources (DER), the array requires continuous, segment-level monitoring and control to maintain day-to-day efficiency and plan predictive maintenance. It cost about $1 million, but received government grants that were key to securing corporate buy-in. For instance, Phoenix Contact installed a 960-kilowatt photovoltaic (PV) array in 2021 with more than 2,600 panels on the roof of its logistics center at its U.S. It can also give some much-needed solidity to less-tangible promises and plans. One of the best ways to get some sustainability experience is to take on a roll-your-own, do-it-yourself project that teach about unfamiliar processes and solutions.
