Advanced Energy® Introduces A Utility-Scale Solar Inverter With Unsurpassed 97.5 Percent CEC-Weighted Efficiency Rating (Pending)

New inverter delivers more power, faster ROI and higher energy harvests long term

Nearly 30 years of experience delivering photovoltaic power solutions culminate in the
500 kW Solaron® inverter featuring optimized balance-of-system architecture

FORT COLLINS, Colo., Oct. 7, 2008—Advanced Energy® Industries, Inc. (NasdaqGM: AEIS) today introduced its newest Solaron® offering—a 500 kW, utility-scale, transformerless, grid-tie photovoltaic (PV) inverter. Extending the Solaron portfolio beyond inverters for commercial and small-scale utility installations, the 500 kW inverter achieves similar, unsurpassed efficiencies as other Solaron models—97.5 percent CEC-weighted (California Energy Commission) efficiency rating (pending).

In addition to delivering more power per inverter for utility-scale installations, the newest Solaron model delivers previously unachievable return on investment (ROI)—from installation through decades of energy harvests. Specifically, before installation is complete, integrators can save tens of thousands of dollars per panel section because multiple Solaron inverters can be routed into a single, medium-voltage station. In operation, unbeatable Solaron efficiencies enable power producers to achieve higher energy harvests over an inverter’s lifetime, resulting in more favorable landed cost-per-kilowatt-hour ratios than was possible until now. Moreover, in addition to the savings from our transformerless design, integrators who choose particular Solaron options can save up to 50 percent on specified material costs like cables, achieving improved ROI even before installation is complete.

The AE Solaron suite of products, services and accessories deliver predictable, optimal performance for decades. Features such as AE’s Integrated Data System™ (IDS™) with instant access to Solaron data from anywhere at anytime and AE’s SafeGuardSM wholly-customizable, comprehensive service program are part of the Solaron optimized balance-of-system (BoS) architecture, which can proactively maximize system uptime, power generation and inverter life.

Solaron® 500 kW Utility-Scale PV Inverter
Designed for utility-scale installations, the Solaron 500 kW inverter features a durable, transformerless, grid-tie design, converting raw DC power from solar-cell arrays to high-quality AC-grid electricity. With its robust controls and patented, soft-switching technology, the Solaron inverter achieves 97.5 percent CEC efficiency (pending). A wide MPP (maximum power point) tracking window ensures maximum, day-long power processing. Both local and remote communications and control are always available via AE’s Solaron IDS integrated data system. Moreover, a comprehensive portfolio of services offerings—from installation assistance to long-term warranties and maintenance programs—allows integrators and power producers to continuously operate Solaron inverters at optimal performance for decades.
