2.1 Intended Use

SG5KTL-MT/SG6KTL-MT/SG8KTL-M/SG10KTL-M/SG12KTL-M; a transformerless 3-
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. The
intended usage of the inverter is illustrated in
system".
Inverter cannot connect the PV strings whose positive and negative terminals
need to be grounded.
Do not connect any local load between the inverter and the AC circuit breaker.
Inverter is applicable only to the grid-connected PV system. Any other usage is
strictly forbidden.
