1.General Information
1.1. About this Manual
This manual is to provide the explanation and procedures for installing,
operating, maintaining, and troubleshooting the below solar inverters:
RPI M6A/ RPI M8A/ RPI M10A
1.2. Product Description
This device is a 3-phase grid-tied solar inverter which does not support off-
grid functionality.
The operation of solar inverter is shown as Figure 1-1.Inverters convert the
DC input power supplied from the PV Array into 3-phase AC output power to
Grid.
