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 current 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 en-
ergy 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 ac-
cordance with IEC 61730, application class A. It is not allowed 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 cov-
ered by warranty.
• Any use other than the one described in this document is not permitted.
• During the installation and operation of the inverter, please ensure that the posi-
tive or negative polarities of PV strings and those of batteries do not short-cir-
cuit to the ground. Otherwise, an AC or DC short-circuit may occur, resulting in
equipment damage. The damage caused by this is not covered by the warranty.
• Do not short-circuit the Backup port during operation. Otherwise, the inverter
or power distribution system will be seriously damaged. The loss is not covered
by the SUNGROW warranty.
• Do not connect any local load between the inverter and the AC circuit breaker.
• 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 can-
not guarantee backup power in all circumstances.
• The inverter applies only to the scenarios described in this manual.
