The IOTH2406 carries CE marking and is supplied with a 1 Year warranty.
The Felicity Solar IOTH2406 is a 0.25 kg WiFi monitoring module that puts an inverter online. Its RJ45 port is wired PIN4 RS485-B, PIN5 RS485-A, PIN6 12V DC input and PIN7 GND, it joins a 2.4G WiFi network, and it sends readings to the shine.felicitysolar.com portal. That pin-out is the IOTH2406's own: the RS485 pair sits on PIN4 and PIN5, while PIN6 carries the module's 12V DC supply and PIN7 the ground, so a single RJ45 lead brings both the data pair and the power feed to the module. Once it is powered, the IOTH2406 associates with a 2.4G WiFi network on site and forwards what it reads to shine.felicitysolar.com, which opens in an ordinary browser. At 0.25 kg the IOTH2406 belongs in the commissioning kit rather than in the switchgear cabinet. The IOTH2406 carries CE marking and is supplied with a 1 Year warranty.
