  • Page 11: Description Of The System

    Operation and installation manual Page 11 of 82 (PVI-10.0/12.5-OUTD-xx Rev:1.2) DESCRIPTION OF THE SYSTEM The AURORA inverter is capable of feeding a power grid using the power generated by photovoltaic panels. Photovoltaic panels transform the sun-radiated energy into electrical energy in the form of direct (DC) current (through a photovoltaic field, also known as PV generator).
  • Page 12 Operation and installation manual Page 12 of 82 (PVI-10.0/12.5-OUTD-xx Rev:1.2) Fig.2 - Array Composition WARNING: Aurora DC voltage input shall not exceed 850 Vdc or damages to the equipment could result. Overvoltage up to 900 Vdc is allowed for 2 hours per day. At any rate, exceeding 850 Vdc input causes an alarm warning by AURORA.
  • Page 13 Operation and installation manual Page 13 of 82 (PVI-10.0/12.5-OUTD-xx Rev:1.2) The total current of an array must also be within the capability limits of the inverter. For AURORA, the maximum current from any input can never exceed 18 Adc. AURORA PVI-10.0/12.5-OUTD-xx models can serve two separate arrays. If the photovoltaic system exceeds the capacity of a single inverter, it is possible to add more AURORA inverters to the system and connect every one of them to a suitable section of the photovoltaic field on Dc side, as well as to distribution grid on...

    Operation and installation manual Page 72 of 82 (PVI-10.0/12.5-OUTD-xx Rev:1.2) SPECIFICATIONS Input values WARNING: the photovoltaic field and system wiring shall be set up so that PV input voltage is lower than maximum limit, regardless of the model, number and operating conditions of the chosen photovoltaic panels. Since panel voltage also depends on operating temperature, choose the number of panels for each string considering the minimum ambient temperature foreseen for that specific area (see table A).

    Operation and installation manual Page 77 of 82 (PVI-10.0/12.5-OUTD-xx Rev:1.2) Power Derating To allow safe inverter operation both from a thermal and electrical point of view, the unit automatically decreases power input into grid. Derating can occur in two cases: Power derating due to ambient conditions Derating entity and the temperature at which derating will start depend on many operating parameters, apart from the ambient temperature.
