2.1 Intended Use
SG2K-S / SG2K5-S / SG3K-S / SG3K-D / SG3K6-D / SG4K-D / SG4K6-D /
SG5K-D / SG6K-D, a transformerless single-phase PV grid-connected inverter,
is an integral component in the PV power system.
The inverter is designed to convert the direct current power generated from the
PV modules into grid-compatible AC current and feeds the AC current to the
utility grid.
Any use other than the intended use is not permitted.
The inverter must only be operated with PV strings of protection class
II in accordance with IEC 61730, application class A. It is not permitted
for the positive pole or the negative pole of the PV strings to be
grounded. This can cause the inverter to be destroyed.
Damages to the product due to a faulty or damaged PV installation are
not covered by warranty.
The intended use of the inverter is illustrated in Fig. 2-1.
