Prosol has increased its initial order for Bidirex inverters and has accelerated inverter deliveries.

The Sonnenbatterie line of solar based residential and commercial management systems will be introduced to the North American market for the first time at the Inter-solar North America Exhibit at Moscone Center in San Francisco, California, from July 9 - 11. Sustainable Energy personnel will be on hand at the Sonnenbatterie booth (Booth #8245) to provide technical background and support on the features and functionality of the Bidirex inverter that is powering Sonnenbatterie products.

"We are pleased with these developments and proud to be able to play a role in contributing to the Sonnenbatterie success everywhere. Prosol Invest's decision to standardize on the Bidirex energy storage inverter validates our core design philosophy to deliver a globally certified platform that is software configurable for multiple market applications," said Justin Holland, COO of Sustainable Energy. "The result is lower cost, higher reliability, and the ability to quickly develop and deploy integrated product solutions in response to changing market conditions."

About Bidirex

The Bidirex inverter is a high efficiency, bi-directional, grid-interactive inverter, specifically designed to connect distributed low voltage generation and storage systems to smart grids and micro-grids. The Bidirex inverter combines the highly flexible "AC coupled" design, which enables complete flexibility to retrofit or build out system incrementally, with the highest round trip electrical conversion efficiencies in the power industry. Bidirex moves seamlessly from grid-interactive to grid-independent operating modes and is easily integrated with most advanced battery technologies.
