The Solis S3-WiFi-ST data logger links a Solis inverter to the SolisCloud monitoring platform over Wi-Fi. It allows remote commissioning, real-time monitoring, fault alerts and ongoing performance checks without a site visit.

Key features

• Connectivity, Wi-Fi link to the SolisCloud monitoring platform
• Inverter connection, RS485 port on compatible Solis inverters
• Monitoring, real-time data with fault alarm notifications
• Installation, plug and play setup
• Status LED, visual confirmation of working state
• Reset button, one-key data transmission and debugging

How it works

The S3-WiFi-ST connects to the inverter through the RS485 communication port and sends performance data to SolisCloud over the local Wi-Fi network. Once linked, the system can be commissioned, monitored and maintained remotely, cutting down on installer call-outs and giving owners visibility of their generation data at any time.

Key inverter parameters are tracked in real time, and the logger triggers fault alarms if the inverter reports an error, so problems can be spotted quickly. The reset button lets engineers resend data or restart communication with the inverter during commissioning or troubleshooting, without needing to access the inverter directly.

Applications

• Remote monitoring of Solis grid-tied and hybrid inverters
• SolisCloud commissioning and ongoing performance management
• Residential and commercial solar installations

Installation notes

The logger connects to the inverter RS485 port with the supplied cable. A stable Wi-Fi signal must be available at the inverter location before fitting. The data logger itself is a low-voltage communications device, but the inverter must only be installed and serviced by a qualified electrician or MCS-accredited solar installer.
