CALGARY — Sustainable Energy Technologies Ltd. will speed up production of its solar energy inverters for the German market with a $500,000 investment from Doughty Hanson Technology Ventures (DHTV).

Sustainable Energy Technologies Ltd. will speed up production of its solar energy inverters for the German market with a $500,000 investment from Doughty Hanson Technology Ventures (DHTV).

The Calgary developer and manufacturer of intelligent power inverters said the PARALEX inverters, which provide high efficiency conversion of low voltage direct current, will be delivered under a previously announced multi-year deal with an unidentified European developer of solar battery systems.

“Sustainable Energy’s inverter is a natural fit for the energy storage market with distinct efficiency, cost and integration advantages that make it compelling. We believe this market presents a large opportunity for the company and we continue to work with management to help make it a reality,” said George Powlick, managing director of UK-based DHTV in a release.

Solar batteries store solar power for use during peak demand periods, reducing demands on the power grid and helping to create “smart grids” that can react to sudden power swings and free up stored energy when needed.

Sustainable Energy’s energy storage inverters manage the connection of the battery to the power grid and to the homeowner, transitioning from charging to discharging the batteries, to optimize use of the solar energy.

PARALEX connects solar panels in parallel, eliminating losses from module mismatching. Each module in a photovoltaic array operates at its optimum power level, independent of the others. The result is a higher total system yield of between 5% and 15% per kilowatt installed, which educes losses from shading, dust coverage and obstructed sunlight.

There’s also a safety factor. The lower voltage reduces the risk of fire and arc faults.

The company’s website says Sustainable Energy has the capacity to manufacture 900 units per month in Guelph, Ont. but it can “easily” double production.

Germany and Italy are seen as “explosive markets” for residential storage and the company expects tens of thousands of systems to be installed in Germany alone this year many as 9,000 megawatts to be installed in Europe over the next six years, according to Italian energy consultant BIP.

Sustainable Energy is forecasting delivery of a minimum 10,000 inverters to Germany over the next 30 months with the potential for more than double that amount over the same period.
