Solis S3 Wi-Fi Data Logger for Solar Inverter Monitoring – S3-WIFI-ST(4PIN)

The Solis S3-WIFI-ST 4-Pin Wi-Fi Data Logger is a compact wireless monitoring accessory designed to connect compatible Solis solar inverters to the SolisCloud monitoring platform. Featuring a convenient plug-in design, 4-pin communication interface, and 2.4GHz Wi-Fi connectivity, the S3-WIFI-ST enables users and installers to remotely monitor solar system performance, review operating data, and access inverter information through the SolisCloud mobile application or desktop website.

Designed for simple installation, the S3-WIFI-ST connects externally to the inverter's compatible communication port and transmits operating information to SolisCloud through an available Wi-Fi network. Once configured, users can access supported system information, including inverter voltages, currents, operating conditions, and fault alarms.

The logger also supports remote inverter firmware updates and compatible inverter setting adjustments through SolisCloud, providing additional convenience for system maintenance and troubleshooting.

For installations with multiple compatible inverters, the S3-WIFI-ST supports monitoring of up to ten inverters through an appropriately configured RS485 daisy-chain connection, allowing multiple devices to communicate through a single data logger.

Built for demanding installation environments, the logger features a NEMA 4X-rated enclosure, three LED status indicators, and a low-power design. Its straightforward connection method makes it a practical accessory for compatible residential and larger solar photovoltaic installations.

Important Compatibility Note: The S3-WIFI-ST is not compatible with certain Solis S6 hybrid inverter models. For S6-EH1P(3.8-11.4)K-H-US hybrid inverters, Solis specifies the S4-WIFI-ST logger or another compatible Solis data logger. Always verify the inverter's communication port and logger compatibility before purchasing.

Wi-Fi Requirement: The S3-WIFI-ST supports 2.4GHz Wi-Fi networks only and does not support 5GHz-only wireless networks.
