System Introduction
The inverter is a transformerless 3-phase PV grid-connected inverter. As an integral compo-
nent 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 to feed the AC current
into the utility grid.
Do not connect any local load between the inverter and the AC circuit breaker ex-
cept for the tracking axis.
•
When designing the system, ensure that the operating ranges of all devices that
are connected to the inverter meet the requirements of the inverter.
•
The inverter is only applicable to the scenarios described in the manual and
cannot be used in other situations.
The intended usage of the inverter is illustrated in the following figure.
