Solis S2-WL-ST Data Logger (4-Pin) | WiFi & LAN | Up to 10 Inverters

Solis S2-WL-ST (4-pin) is a 2-in-1 data logger that sends system data to SolisCloud via either WiFi or an Ethernet cable. It connects to the inverter's external 4-pin COM port and is secured with the locking ring.

• WiFi and LAN in one device
• Monitors up to 10 inverters connected in series via RS485
• 5-minute data interval with fault alerts
• Commissioning via Bluetooth 4.2 or browser
• IP65: operating range from −30 °C to +65 °C
• 2-year standard warranty for Solis accessories

WiFi or LAN without a second device

If WiFi at the inverter is unreliable, connect an Ethernet cable instead. The WiFi connection uses the 2.4 GHz band; 5 GHz networks are not supported. For LAN, use an RJ45 plug without a bulky protective housing so that the seal closes correctly.

Up to ten inverters with one logger

Up to ten inverters can be linked via RS485 and monitored with one data logger. Each device in the communication chain requires its own slave address.

Quick fault diagnosis

Three LEDs separately indicate power, network and inverter communication. The reset button can send data immediately, open configuration mode or reset the connection.

Compatible devices with a 4-pin COM port

• S6-GR1P(0.7–3.6)K-M and S6-GR1P(2.5–6)K single-phase grid-tied inverters
• S5-GR3P(5–20)K, S5-GC(25–40)K and S5-GC(50–60)K three-phase inverters
• S5-EH1P(3–6)K-L single-phase hybrid inverters
