or if the system is extended. In these cases the new inverters must also be provided with the extended parameters
again.
The extended parameters are only available starting from inverter firmware version 800.2.20 or higher. The firm-
ware version can be checked on the inverter menu:
► "F1" /
Numerical list / Parameters 1.1 to 1.3
Current firmware versions and update instructions can be found at
www.refu-elektronik.com/en.
Set the following parameters on the inverter's operating display:
1. Press "F1"
2.
Select Numerical list, press "ENTER".
3. Set parameter number 0407 press "ENTER"
4. Select sub parameter 0407,3, press "ENTER"
5. Enter "2"
[Communication type RS485: Solarlog], press "ENTER".31], press "ENTER".
6. Set parameter number
0420 press "ENTER"
7. Select sub parameter
0420,3, press "ENTER"
8. Enter the numerical value
9600, press "ENTER"
9. Using the installed DC isolating switch turn the inverters on and off briefly so that the settings are activated.
Note
The numerical value "2" under point 5 in the settings refers to the old Solar-Log protocol and the value
"1" to the native protocol for active and reactive power control.
The value under point 8 refers to the inverter's baud rate and is 9600 for the old Solar-Log protocol
and 57600 for the native protocol.

•
Recommendation: Continuous numbering starting with 1.
•
Setting: Using the inverter operating display
•
Procedure: Start according to the inverter's instructions
Note
To use active and reactive power management, all of the inverters need to be set to:
•
Protocol 1
•
57600 baud
•
Parameter 1164 = 2
Note
A maximum of 31 inverters can be connected per RS485 bus.
