1 Introduction
The inverter is only designed for operation in grid-connected
PV systems. The inverter converts direct current from PV
modules into grid-compliant three-phase alternating current.
For operation, the inverter must be connected to a utility grid
and with a sufficient number of PV modules. The inverter is
not suitable for other applications (such as operation with
batteries or wind turbine systems).
The PV system consists of four main components:
• Inverter
• PV array junction box
The PV array junction box enables the bundling of the
necessary number of PV strings for the inverter. Each
inverter requires a PV array junction box.
• SMA Inverter Manager
The SMA Inverter Manager is always required for the
operation of the inverter. Up to 42 inverters can be
connection to each SMA Inverter Manager. The
SMA Inverter Manager handles all communication of
the inverters. It serves as central interface for data
acquisition systems, upload to cloud services and
power-plant control.
• Local commissioning and service tool (LCS-Tool)
The LCS-Tool is required for commissioning and
servicing the inverter via the SMA Inverter Manager.
The LCS tool is the primary user interface for the PV
system.
