Product overview
Up to ten inverters on one logger.
The S2-WL-ST (4 Pin) collects data from as many as ten Solis inverters chained over RS485 and sends it to SolisCloud over Wi-Fi (2.4 GHz) or Ethernet. It keeps inverter data while the network is down — up to 30 days for a single inverter, less as more are connected — and backfills it once the connection returns. Bluetooth is available for set-up nearby, and Modbus TCP is supported.
- Wi-Fi and LAN802.11 b/g/n at 2.4 GHz, or Ethernet at 10/100 Mbps over up to 100 m. 5 GHz networks are not supported.
- One to ten invertersConnects up to ten Solis inverters that are linked hand in hand over RS485.
- Offline data storageStores up to 30 days of data for one inverter and resumes transmission after an outage.
- IP65Rated IP65 for −30 °C to +65 °C operating temperature.
