The low network impedance of an AC network means that a small DC voltage from the grid connected inverters creates a large DC current injection. This DC current is not a fault current, but is caused by asymmetry between the positive and negative half-wave of the current. . Reason 1: The DC switch is not turned off. Solution: Check whether the DC switch of the inverter is in the "ON" position. The nominal frequency range for M190, M210 and D380 microin-verters is 59. After the inverter has switched off due to high DC ripple voltage, it waits 30 seconds and then restarts. Excessive DC current injection into an AC network can cause problems like transformer saturation, however, which will cause. . Safety First: Before checking any connections, ensure you have flipped both the AC and DC disconnect switches (if applicable) to the OFF position. Check Fuses and Breakers: Verify the main circuit breaker for the solar system on. .
