Monitoring Device Terminal; Drms Port - Growatt WIT 50K-A User Manual

6.5.4 Monitoring Device Terminal

The WIT inverter is equipped with a USB port that allows for remote monitoring when
connected to a monitoring device, such as a USB-to-WiFi module, ShineWiFi-X, Shine4G-
X, ShineLan-X, and others. Additionally, you can perform software updates using a USB
flash drive.
1. Remove the waterproof cover from the USB port.
2. Insert the USB-to-WiFi module, ensuring that the triangle icon is facing upward, and
then secure it by tightening the screw, as shown in Fig 6.14. If the module is working
properly, its LED indicator will light up.
NOTE: Before you leave, please ensure that the monitoring device is removed and the
protective cover should be reinstalled to avoid any water damage.

6.5.5 DRMS Port

The WIT inverter comes with a DRMS port. Users can choose to connect to this terminal if
required by local regulations. The connection procedure is as follows:
1. Connect the communication cable to the port as required. The DRMS port is a standard
RJ45 connector, so you can establish a connection following the typical Ethernet wiring
method.
2. Remove the dustproof cover from the DRMS port and check whether there is a
waterproof silica gel pad. Insert the cable and tighten the rubber ring to prevent any
loose connections.
3. Once the cable connection is complete, reinstall the dustproof cover.
Table 6.8 describes the DRM requirements.
