The WebdynSun gateway is the solution for monitoring your photovoltaic systems. It monitors, collects and analyses the data from your photovoltaic plant remotely and in real time. The gateway combines all the indicators output from the inverters, electric meters and external sensors (sunshine, temperature and so on) in a single unit. It is designed for the preventive and curative remote maintenanc
e of the plant and real-time monitoring of electrical power generation. The gateway not only provides the opportunity to offer additional after-sales services to your customers, but also gives feedback on the equipment used in your architecture. The gateway optimises the range of products offered to your customers, while also maximising the output from your systems. THE PLATFORM
The Webdynsun hardware platform consists of an extremely compact unit compatible with DIN Rail standards for electric boards. This unit houses all the dedicated interfaces of the plant, the wireline network interfaces (Ethernet and STN), and the wireless network interfaces (GPRS). The basic functions of the Webdynsun gateway supervise:
• An inverter bus : up to 100 inverters (more than 200 inverters are compatible)
• Three electric meters with a French protocol TIC,
• Sunshine and temperature sensors,
• On-off inputs/outputs (4-2),
• Modbus interface (display, circuit breaker, etc.),
• Two pulse inputs for meter index. OPERATING PRINCIPLE
The WebdynSun gateway operates in advance data logging mode. From a configuration file and/or local HTML interface, which describes all the equipment comprising the plant (inverters, meters, sensors, etc.), the WebdynSun gateway scans and collects the data related to each item of equipment. This data is then formatted (csv) and sent periodically over the GPRS, Ethernet or telephone network to a central server. According to the state of some of these variables, alarms may be triggered and sent by the system in real time. Conversely, the gateway can receive command files from the central server to operate the actuators. When first powered on, the gateway connects using an IP address to a factory server and downloads the full configuration: hardware, server address, data format, collection frequency, etc. When the configuration is complete, data collection can commence automatically and periodically. The gateway configuration and firmware can be remotely updated. Gateway services
