reconnection time;
Step 4:
when the inverter enters the normal mode, the power will be fed into the grid, and the
LCD will display the power generation.
5. Communication and Monitoring
5.1. Summery
KY3GT-20K/KY3GT-17K/KY3GT-15K/KY3GT-12K/KY3GT-10K inverter provides RS-485,
WIFI, GPRS and other communication interfaces, and is equipped with a monitoring system,
which can remotely browse the output voltage, current, grid frequency, fault and other
information. At the same time, these parameters are stored in the local PC to facilitate the
query of historical records.
5.2. Communication
Users can browse the data of the inverter remotely through the communication interface, and
the inverter provides two kinds of communication interfaces.
5.2.1. RS-485 Communication
RS-485 is usually used for local monitoring or connecting to the third-party data collector:
when connecting to the local monitoring, the RS-485 interface of the inverter can be
connected to the USB interface of the computer through the USB to RS-485 converter, and
the maximum length of the RS-485 cable should not exceed 1200m. Users can view and
record the current power generation, working status and error information of the photovoltaic
power station through the PVCs software installed on the computer.
Be careful:
1. The wiring sequence of 2 terminals of 1 RS-485 cable shall be
consistent.
2. If the customer needs RS-485 to communicate with inverter,
they need to purchase USB to RS-485 converter.
5.2.3. WiFi / GPRS Communication
KY HYBIRD series
inverter can be configured with a WiFi / GPRS communication module to
realize communication networking.
5.3. Monitoring
1. Local monitoring system
The local monitoring software is connected to the inverter through USB to RS-485
