Wireless communication gateway for Sigma Solar Server and solar tracker networks<\/span><\/strong><\/span><\/p>\n

The RS485 to LoRa Master Converter provides a reliable wireless communication link between the Sigma Solar Server and compatible SAT CONTROL solar tracker positioning devices. The converter replaces long RS485 communication cables by converting half-duplex RS485 communication using the SAT CONTROL modified MODBUS-based protocol into a LoRa-based wireless network operating in the 433 MHz frequency band. Communication is bidirectional. RS485 data received from the Sigma Solar Server is transmitted wirelessly to the connected solar tracker devices, while responses from the field devices are converted back into wired RS485 communication. The Master Converter is installed on the Sigma side of the communication network and is designed primarily for installation inside electrical and control cabinets.<\/span><\/p>\n

Reliable wireless communication for solar power plants<\/span><\/strong><\/span><\/p>\n

The converter is particularly suitable for medium-sized and large solar power plants where conventional RS485 cabling would be difficult, expensive or exposed to electrical disturbances. By replacing long communication cables with a LoRa wireless connection, the system can:<\/span><\/p>\n

    \n
  1. Reduce communication cable installation costs.<\/span><\/li>\n
  2. Simplify solar plant installation and expansion.<\/span><\/li>\n
  3. Bridge long distances between the control room and solar tracker fields.<\/span><\/li>\n
  4. Reduce problems caused by ground potential differences between different sections of a solar power plant.<\/span><\/li>\n
  5. Limit the propagation of surge and lightning-related damage through communication cables.<\/span><\/li>\n
  6. Provide communication with solar trackers located in areas where cable installation is impractical.<\/span><\/li>\n
  7. Support communication routing to devices without a direct line of sight.<\/span><\/li>\n<\/ol>\n
