- There is too much AC load connected at the moment the relay needs to switch off.

- The AC input voltage slowly drops before it is being rejected by the Multis. Typically happens in installations with a genset. Especially when combined with AC loads that increase their current draw when the AC voltage drops: at the moment the Multis or Quattros decide to switch off, the current through the relays is too high to open them.\\ \\ Solution: Make the Multis or Quattros disconnect earlier: increase lower limit of AC input voltage in VEConfigure3. For example to 210 VAC. The factory setting is 180 VAC. \\ \\ | - The AC input voltage slowly drops before it is being rejected by the Multis. Typically happens in installations with a genset.
