2 Product Introduction
2.1 Intended Usage
SG3KTL-M, SG4KTL-M and SG5KTL-M (They will be referred to as inverter hereinafter
unless otherwise specified), single-phase without transformer string inverter, is a
crucial unit between the PV arrays and the utility grid in the small-scaled 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 the alternating current into the utility grid. An example about intended
usage of the inverter is shown in Fig. 2-1.
Where the positive or negative terminal of PV strings needs to be grounded,
inverter cannot be connected to PV modules of this type.
