The Solis S2-WL-ST (4-Pin) is a high-performance hybrid data logging adapter engineered for comprehensive PV system oversight via both WiFi and LAN connectivity. This system enables real-time data communication with SolisCloud for up to 10 inverters simultaneously through an RS485 chain. Featuring an IP65 protection rating and Bluetooth BLE4.2 support, the stick provides a robust solution for precise energy management in demanding industrial environments.

  • Hybrid Connectivity: Flexible support for wireless WiFi (2.4G) and wired LAN connections for maximum network uptime.
  • Multi-Inverter Support: Capability to monitor <10 inverters simultaneously via a professional hand-in-hand RS485 link.
  • Ethernet Performance: Equipped with a 10/100 Mbps adaptive port with a communication distance of up to 100 meters.
  • Bluetooth Debugging: Integrated BLE4.2 allows for rapid local configuration and troubleshooting via the mobile application.

Engineering-Grade Data Management for Solis PV Systems

The S2-WL-ST (4-Pin) is a critical component within the Solis inverters portfolio, offering network redundancy for mission-critical installations. The adapter is externally mounted to the 4-pin COM port using an Externally Insert + Twist Lock mechanism for a secure, vibration-resistant connection. With a power consumption of ≤2W and a 5-minute data interval, it delivers consistent insights into system status. Three diagnostic LEDs provide immediate visual feedback on network link, communication, and power status, facilitating efficient on-site commissioning.

Note: For LAN connections, use only an RJ45 plug without a protective shell due to limited installation space within the IP65 enclosure.
