*** Backwoods recommends that Aurora inverters and products only be purchased for installation by a certified electrician. While operational tech support is available to any user/operator, parent company ABB and Aurora limit in-field tech support for hardware changes/upgrades only to installations that are supported by a certified electrician that is on site. ***
**Reduced Price, one unit only. Power One is transitioning their Aurora string inverter product line to add Arc Fault Protection compliance with the NEC 2011 requirements.
As of this time only 14 states have adopted the Arc Fault requirements. Check your local electric code requirements. If not yet adopted, this lower priced unit may be perfectly suitable for your application.**
The Aurora PVI series are some of the most flexible string inverters available. PVI inverters have two separate MPPT inputs, allowing for two sub-arrays to be configured with differing string lengths, orientations, or even different PV modules. Conditions on one string will not affect the other. Additionally, the PVI inverters have two input terminals for each separate MPPT section allowing as many as four strings of modules (two on each MPPT) to be connected without separate string fusing. Both MPPT inputs can also be paralleled for use with a single array. A wide input voltage range allows for low wattage installations with reduced string sizes where needed.
An integrated LCD displays real-time operating parameters, and RS-485 and USB interfaces can connect remote monitoring systems. An integrated DC disconnect is standard on all “S” models.
Aurora PVI inverters can produce full-rated power at ambient temperatures up to 122°F (50°C). The fan-less design and NEMA 4X enclosure provide a water
and airtight seal.
Output voltage can be set for 240 VAC split-phase, or 208 VAC or 277 VAC (480 VAC WYE) for 3-phase systems (3 inverters required for phase balancing). All PVI inverters are Listed to UL1741/IEEE1547 and CSA-C22.2 N.107.1-01 for the U.S. and Canada.
