+ | The three root causes of the error can be (from most common to least common): | ||
+ | |||
+ | 1) In most cases, when you see Error 11, its due to an installation error: | ||
+ | * Please verify that the neutral is connected to earth on the supply side. In many countries this is done by the utility in the transformer cabinet (a TN network). | ||

- 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.
