Installation and Operator’s Manual Page 10 of 108 (PVI-3.0/3.6/4.2-OUTD-x-US Rev: 2.1) FOREWORD This document contains a technical description of the Aurora Photovoltaic Inverter which provides the installer and user with the information required for its installation, operation, and use.
The AURORA is capable of handling 2 separate arrays. If the output of photovoltaic system exceeds the capacity of a single inverter, additional Aurora inverters can be added to the system; each inverter will be connected to an adequate section of the photovoltaic field on the DC side and to the grid on the AC side.
The inverter is grid-connected, transformer-less, robust and of high conversion efficiency. This manual contains information about the inverter, which will provide guidelines on connecting the inverter into the PV power system and how to operate the inverter. The manual cannot include all information about the PV system.
The electrical power and signals wiring from the inverter to the AC Grid and to the photovoltaic panel are connected through the Switch Box as described in Fig.11 SB-01 – "DC Switch Box Layout" –using the access windows in pos “A” for the power cables and the windows in pos “D” for the signal cables.
Fig. 2-5 shows the main circuit of the inverter. The MPPT is utilized for DC input to ensure the maximum power from the PV array at different PV input conditions. The inversion circuit converts the DC power into AC power and feeds the AC power to the utility grid through the AC terminal.
Check the inverter’s DC side and string connections (see Par. 5.3). • Check the documentation on the sizing of the photovoltaic system and evaluate a possible change to the start-up voltage on the display (Ref. Par. 11.1). The inverter does not establish parallel connection with the grid. Insulation resistance to the photovoltaic eld <1Mohm.
