\"SSE<\/p>\n

The Clean Energy Council has announced the de-listing of all Shanghai Surpass Sun Electric Co Ltd’s (SSE) solar inverters from its approved products list, citing potential safety issues.<\/p>\n

The de-listing occurred after the failure in testing by the CEC of an SPS5KTL-ED model grid-connect inverter for compliance with AS 4777-2 (Grid connection of energy systems via inverters).<\/p>\n

“As a result of failing the Passive Anti-islanding test when programmed for Australia and other issues, all of SSE’s inverters were de-listed on 29 January 2019,” states the CEC. “This failure is regarded by the CEC as a potential safety issue as the inverter may not shut down under some grid fault conditions and may potentially damage other equipment.”<\/p><\/blockquote>\n

In its announcement the CEC didn’t provide any further detail as to what the “other issues” were.<\/p>\n

Anti-islanding is an important safety feature that detects the loss of grid power in a fraction of a second and switches off the solar inverter automatically. This not only protects grid equipment, but also those who may be working on rectifying a fault.<\/p>\n

All SSE solar inverters were de-listed as it isn’t practical for the CEC to test all models, so it is taking the results of the SPS5KTL-ED test as indicative of other devices until such time it is demonstrated otherwise.<\/p>\n

While the CEC’s web interface<\/a> no longer lists SSE models, a PDF version of the approved inverters list dated January 25 notes other models approved at that time were:<\/p>\n
