Product Introduction
2.1
Intended Usage
SG2K5TL-31, SG3KTL-31 and SG4KTL-31(They will be referred to as inverter
hereinafter unless otherwise specified), single-phase without transformer string
inverters, are crucial units between the PV arrays and 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 show 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.
