Product Description
2.1
System Introduction
The inverter is a transformerless 1-phase hybrid inverter. As an integral component in
the power system, the inverter is designed to convert the direct current power generated
from the PV modules or batteries into grid-compatible AC current and feeds the AC cur-
rent to the utility grid.
The 1-phase hybrid inverters are applicable to both on-grid and off-grid PV systems.
With the integrated Energy Management System (EMS), they can control and optimize
the energy flow so as to increase the self-consumption of the system.
•
The inverter must only be operated with PV strings with class II protection in
accordance with IEC 61730, application class A. It is not allowed for the posi-
tive 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.
•
Any use other than the one described in this document is not permitted.
•
For the TT utility grid, the N line voltage to ground must be 30 V or less.
•
The utility grid must be a TN system for the off-grid application.
•
The system is not suitable for supplying life-sustaining medical devices. It
cannot guarantee backup power in all circumstances.
