2 Product Introduction
2.1 Intended Usage
SG36KTL-M (It will be referred to as inverter hereinafter unless otherwise specified)
which is a 3-phase string inverter without transformer, is a crucial unit between the
PV strings and utility grid in the PV power system.
Inverter is dedicated to converting direct current power generated by the PV
modules into alternating current, which conforms to parameters of local utility grid,
and feeds it into the utility grid. The intended usage of the inverter is illustrated in
Fig. 2-1.
Inverter CANNOT be connected to the PV modules, the positive or negative
terminal of which needs to be grounded.
