Major PV inverter manufacturer, Sungrow Power Supply, has used its 1,000Vdc SG30KU string inverters for the first time in Canada, making the rooftop project the first 1,000Vdc system deployed there.
According to Sungrow, all rooftop PV system installations in Canada have been 600Vdc.
As with the move by large utility-scale PV power plants to higher voltages to reduce LCOE costs, notably in cabling and secondary equipment such as combiner boxes, the same benefits are expected in the commercial rooftop segment.
“There is a perception that the Chinese are not innovative. The fact that our 1,000V string inverters are the first to be used in Canada shows that we are on the cutting edge,” said Mizhi Zhang, the CEO of Sungrow Canada.
Sungrow said that it expected that 1000Vdc and higher voltages would become increasingly popular and that advanced features such as arch flash detection would be integrated into inverters to reduce the risk of fires.
