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 MPPT 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 smaller 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 (models without a DC disconnect are available by special order). 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 UL 1741/IEEE1547 and CSA-C22.2 N.107.1-01 for the U.S. and Canada, and come with a 10-year warranty, which is extendable to 15 or 20 years.
