American Electric Technologies Develops New Utility-Scale Solar Inverters

Houston-based American Electric Technologies Inc. (AETI), a provider of power delivery products for the traditional and renewable energy industries, has added two new models to its 1,000 V Integrated Solar Inversion Station (ISIS) product line.

AETI's ISIS 1000 V product line now includes both 1.0 MW and 1.5 MW solar inversion platforms as inverter-only solutions, or as integrated solutions with a medium-voltage 15 kV or 38 kV class step-up transformer and utility interconnect systems. All ISIS inverters incorporate a master combiner, a DC and AC disconnect switching system, and the inverter system in a NEMA 3R enclosure.

Utilizing the industry's first 1.0 MW solar inverter architecture witness-tested to UL 1741 at 1000 V, the new 1.5 MW ISIS inversion system with the new 38 kV utility interconnect system enables optimization of DC and AC solar performance while meeting ANSI C.37 codes and NFPA safety requirements, according to the company.

The ability to run solar farms at 1,000 V rather than 600 V with the new 1.5 MW UL 1741 platform and 38 kV interconnect system enables utility-scale project developers to implement DC and AC designs at the highest voltage levels, thus reducing balance-of-system cabling costs and power losses from the PV panel through the grid connection point, AETI says.
