Dear experts, I am trying to figure out how to determine correct spacings for non-isolated inverter. According UL1741 OVC IV needs to be considered for inverter. From table 8.1 from UL840 I get a transients of 8,0kV for 450VDC input. Is that correct?
Output of inverter is connected to AC grid 120/240V. This results in 4kV transients. We have no insulation input/output. Which transient level should I then use? 8kV transient on AC output side is almost impossible for the design. Any idea?
