This inverter is a three-phase transformerless string grid-connected inverter, a crucial component of photovoltaic (PV) power generation systems.

The inverter converts the direct current (DC) generated by the PV strings into alternating current (AC) that meets grid requirements and feeds it into the grid.

WARNING:

Do not connect any local load other than the tracking axis between the inverter and the AC-side circuit breaker.

Note:

• The PV modules used in the system must meet 61730-1 Class II.
• When designing the system, ensure that all devices connected to the inverter meet the inverter's specifications.
• This inverter is only suitable for the scenarios described herein and should not be used in other applications.

A typical application scenario for the inverter is shown in the figure below.
