Logger installation guide for KSTAR Inverter
Make:
KSTAR
Type
Solar on Grid string inverter
Available models:
KSG-30K,KSG-36K,KSG-50K,KSG-60K
CONNECTION DAIGRAM:
The communication terminals (RS485) are located at the bottom of the inverter. And there are
two connection terminals on the configuration circuit board: ++ - - terminal blocks.
Figure 1: KSTAR string inverter communication port and connections
Connection Steps
➢Please unscrew the RS485 terminal as shown in A part of Figure 1.
➢Please make the connections from the Terminal Block to Holmium Dlog as mentioned in Table 1
Connect the cables from Holmium Dlog to communication port of inverter as shown below

Multiple Inverter
Pin 2 & 4 of Inv-1 is connected to Pin 1 & 3 of next inverter in Daisy Chain.
When two or more inverters are in parallel communication, 2P DIP switch beside RS485 of the last one
should be “ON”. Or else, it may cause communication interruption. That 2P DIP switch is on, means
connecting a 120Ω communication terminal resistance between the R/T + and R/T - )
DEFAULT CONFIGURATION IN HOLMIUM Logger
Inverter ID: 1, 2, 3, 4 .... Continuous numbering starting with 1, (Range: 1 to 247)
Baud Rate: 9600 (Default) (Values: 9600, 19200, 38400)
Data Bits: 8, Stop Bit: 1, Parity: None
CONFIGURATION AT THE INVERTER END
Press Enter on LCD panel and get into settings menu, After entering into the setup interface, the system will
ask to input password, the default password is “00000”.
Setting the BAUD RATE
Option 6 under Settings Menu- 485 Baud rate
If you connect multiple inverters via RS485, set the same baud rate on each inverter.
Set Inverter Baud rate to 9600
Press UP and DOWN to move correcponding options. Confirm
selected option and return back the setup interface by
pressing ENTER button. Press ESC button to cancel choice and
return back the setup interface.

Setting the Inverter ID
The inverter ID is used to identify the inverter in a RS485 connection.
We set a different inverter ID for each inverter in the PV plant to identify the inverters correctly. On the last
inverter in the RS485 connection, switch on the RS485 termination resistor.
Option 5 under Settings Menu- 485 address
Set Date and Time of Inverter
Date and time have to be correct for a precise calculation of the statistics in the inverter itself and in a
monitoring system.
Option 10 under Settings Menu- Date/Time
Set communication protocol
Option 7 under Settings Menu- 485 Protocol
NOTE: The above details are mentioned in the Installation & Operation Manual for Kstar KSG
30K/36K/50K/(60K- HV)/60K on Page 28.
Set correct Inverter IDs
Set correct Date and Time
Press UP/DOWN to increase or decrease the input figure,
confirm input and return back setup interface by pressing
ENTER button, press ESC button to cancel input and return
back setup interface.l value is between 1 and 32.
The input numerical value is between 1 and 32.
Press UP/DOWN to increase or decrease the input figure; press
ENTER button to move the cursor backwards, confirm input
and return back setup interface and move the cursor
frontward and return back setup interface by pressing ESC
button.
Press UP and DOWN to move corresponding options. Confirm
selected option and return back the setup interface by
pressing ENTER button. Press ESC button to cancel choice and
return back the setup interface.

HOLMIUM WORKING:
Ensure correct connections as detailed in the installation guide.
Connection Diagram:
Insert SIM card: Insert the sim card in
data logger. It must not be a JIO SIM
CARD. Required internet data for
uninterrupted operation is 1GB/Month
2G/3G preferred.
Plug antenna: Connect the antenna in
data logger.
Connect power supply: Connect the
power adapter in data logger.
Check functionality:
NOTE: Holmium Dlog will only be able to send data if the GPRS network is available at the installed location.
