Distributed Generation Interactive Inverter(ST6866-1)

Advanced Energy Conversion, LLC


Traditional forms of energy generation are presently a risk to the environment and ecology. Our energy-based society needs electricity, and that demand must be met without a proportional detriment to the environment and significant cost penalty to the customer. Renewable and "green" energy resources are becoming feasible, but the cost associated with converting energy into readily usable form remains too expensive for large scale applications. Developing smaller, less expensive power inverters will enable these technologies to gain wider application.

Project Description

The goal is to fabricate prototype, preproduction prototype, and manufacturing prototype inverters. Each prototype inverter will be experimentally evaluated against the regulatory requirements and used to refine the electrical performance, the manufacturability and the manufactured cost. Along the way, intellectual property issues, manufacturing relationships, and distribution relationships will be forged to ensure commercial success.


Benefits of this project include the creation of several jobs, energy savings, reduction in the use of petroleum or coal, and a more economical design.

Project Results

Part of the issue was that this was the first time AEC ever designed and built a product that had to undergo type testing by an independent lab. As a result, many changes had to be made along the way as part of the learning curve. In the end, the result was a high quality product, the ecoJoule™2500 inverter, which offers some unique features that are expected to make it attractive to the market, including higher efficiency at low input voltage levels that also allows PV panel arrangements that will be minimally affected by shading. AEC is also developing a higher output version (5kW) so the company will definitely benefit from lessons learned with the 2.5 kW inverter developed under this project. AEC’s experience in this inverter technology facilitated the capture of new partnerships and teaming arrangements for applications of its inverter for wind and battery storage systems.
