Applications and use cases
- SolisCloud monitoring for a Solis inverter with the specified compatible 4-pin interface.
- Remote fault and operating-data review for a commissioned PV installation.
Equipment scope / supply scope
- The V4.0 guide lists one Wi-Fi stick, one Wi-Fi antenna and one quick installation manual. Confirm the delivered hardware revision.
- Confirm the exact inverter interface before ordering: this guide describes a 4-pin COM connection, not a universal USB logger.
- The inverter, site internet connection and any additional RS485 cabling are project items unless explicitly quoted.
Installation considerations
- Fit the antenna and connect the logger to the compatible inverter COM port; tighten only the connector ring as instructed.
- Create the SolisCloud plant, bind the logger serial number and configure the site Wi-Fi network.
- For multiple inverters, follow the inverter manual for RS485 wiring and assign a unique address to each device.
