The Local Commissioning and Service tool (LCS) is used to
commission the Inverter Manager and inverters, enabling
them to start injecting power into the grid. With the LCS
Tool it is possible to:
•
Perform software update of the system
•
Read out inverter values (voltage, current, etc.)
•
Display inverter event logs
•
Load custom grid code file (information about
how to obtain custom grid file see
•
Configure portal FTP upload
•
Access commissioning reports
•
Modbus gateway address list
•
Add/replace inverters
The MLX inverters and Inverter Managers must be commis-
sioned via the Local Commissioning and Service Tool (LCS
Tool). Commissioning is required before the MLX inverters
can connect to the AC grid and inject power.
The LCS Tool is available from the download area at
www.sma.de
.
The hardware requirements for the LCS Tool are:
•
PC running Windows
TM
7 and later
•
1 GB HDD
•
2 GB RAM
The LCS Tool must be installed on a local PC drive. The PC
must be connected to the plant network of the Inverter
Manager.
NOTICE
The Inverter Manager must have an IP address assigned
by a DHCP server on the LAN 1 port.
It is important that the PC running the LCS Tool is
connected to the same IP subnet as the Inverter
Manager.
Port LAN 2 is intended for MLX inverters exclusively.

5.3 I/O
Box
The I/O box is used for transmitting the relay state from a
ripple control receiver, provided by the DNO, to the
Inverter Manager over RS-485. An I/O box is required for
each Inverter Manager.
5.4 Weather
Station
Any SunSpec-compliant RS-485 weather station can be
