The total current of an array must also be within the capability limits of the
inverter. The 2000W model of AURORA is capable of handling a single array. For
AURORA the maximum input current shall not exceed 10Adc.
In case the photovoltaic system exceeds the capabilities of a single AURORA
inverter, additional inverters can be added to the system, each connected to a
suitable section of the photovoltaic field on the Dc side, and to the grid on the Ac
side. Each AURORA inverter will work independent of the others and will transfer
to the grid the maximum power available from its own section of the photovoltaic
panels.
The actual decisions on the way the photovoltaic system is structured and wired
depend on a number of factors and considerations, such as type and model of
panels, available area, location, energy targets, as well as on good design practices.
Power-One provides a system configuration tool
on its website (www.power-one
.com) that can assist in modeling the system.

2.2 Data Transmission and Check
In case multiple inverters are used, they can be monitored remotely by using an
advanced communication system based on the serial interface RS485 or on the
Power Line Modem (PLM) technology. For further information, refer to the
corresponding sections of this manual.
