KSTAR WIFI-PLUG5E Stick Logger (Wi-Fi + Ethernet)

The KSTAR WIFI-PLUG5E is a stick logger for KSTAR inverters. It sends inverter data to the cloud platform over Wi-Fi (IEEE 802.11 b/g/n, 2.4 GHz) or through a 10/100 Mbps Ethernet port. It talks to the inverter over RS-485 at 9600 bps and reads one device.

The logger twists onto the inverter with a 4-pin aviation connector. You configure it through the Bluetooth app or from the remote server, and firmware updates arrive over the air. Data uploads every 5 minutes, and a hardware and software watchdog monitors operation.

The IP65 housing measures 150 × 48 × 37 mm and weighs 120 g. It runs on 5 VDC, draws up to 2 W and works from -30 °C to +60 °C.
