EMC filters for solar applications

14th July 2016

Posted By Paul Boughton


Maintenance and repair specialist CP Automation now distributes and fits Roxburgh EMC's innovative high voltage, high performance three-phase EMC filter range. The KMF3420V is specifically designed for use with high kW inverters used in photovoltaic solar power applications.

CP Automation can help customers integrate the filters along with compatible inverters into their solar power systems.

Roxburgh's electromagnetic compatibility (EMC) filters are fitted on inverters to minimise harmful electromagnetic noise that can damage electrical equipment or cause spurious malfunctions.

The high voltage model of the KMF series operates at a voltage rating of 690V, significantly more than competing products that usually only work up to 500V. The innovation came about after a world-leading manufacturer of solar inverters got in touch with Roxburgh and asked it to develop an EMC filter that worked at 690V instead of 600V. The 690V model has the same footprint as the 600V, resulting in significant space savings.

The KMF3420V works at a temperature rating of 65 degrees Celsius, as opposed to the industry norm, 50 degrees. This makes the filters perfect for the difficult conditions of photovoltaic power applications, which present high ambient temperature challenges.

"Renewable energy now provides approximately 18% of global electricity generation," explained John Mitchell, global business development manager of CP Automation. “For that number to continue to rise, solar power generation and distribution needs to be as efficient as possible. That's why quality EMC filters are so important to the industry."
