Smaller, Lighter Solar Inverters – SolarEdge HD-Wave

SolarEdge HD Wave solar inverter

SolarEdge Technologies, Inc. says its new HD-Wave inverter represents one of the most significant advances in solar technology in the past two decades.

The company states its HD-Wave technology reduces the size of the inverter’s magnetic components dramatically through the use of advanced digital processing. A reduction in the number of cooling components required has also been achieved. Among the design improvements are thin film capacitors and standard silicon switches.

HD-Wave will provide improved reliability and efficiency of 99%+ says SolarEdge; supplying more solar electricity at a lower cost.

A side-by-side comparison provided by the company shows the new HD-Wave inverter to be less than 50% the weight and volume of an equivalent string inverter.

“Continued technological progress is required to make solar energy more competitive with fossil fuels,” said Guy Sella, CEO and Chairman of SolarEdge, “and inverters are the key component for accelerating the adoption of solar technology. We believe that our new HD-Wave technology is a significant milestone in the development of solar and further positions SolarEdge as a leader in a thriving industry.”

Lior Handelsman, VP Marketing and Product Strategy of SolarEdge, says HD-Wave is akin to the transition from large glass tube TVs to flat-screens.

HD-Wave technology will be available from December this year – whether this includes the Australian market is unknown at this point. The company states it will officially unveil the first inverter powered by HD-Wave at Solar Power International in Anaheim, California; which is taking place September 14-17.

One of SolarEdge’s previous innovations is the Power Optimizer, which won the company the prestigious Intersolar 2012 Innovation Award.

In May this year, the company announced SolarEdge inverters will be upgradeable to be compatible with Powerwall – Tesla’s home battery energy storage product.

Interest in the development of smaller inverters was cranked up in 2014 after Google offered a million dollars for the best design of a solar inverter around the size of a notebook computer. Up to 18 finalists will be chosen to have their inverters tested next month. The winner of Google’s Little Box Challenge competition will be announced and the inverter unveiled in January next year.
