-Error 11 indicates a failed automatic self-test of the MultiPlus-II or EasySolar-II relays. It is often a result of an installation or wiring issue, though it can also be triggered by a hardware failure.+Error 11 indicates a failed automatic self-test of the MultiPlus-II or EasySolar-II relays. It is often a result of an installation or wiring issue, though it can also be triggered by a hardware failure ​(eg inoperable relays).
  
 If a grid code is selected in VEConfigure,​ then the backfeed relays are tested every time before connecting to the mains. If a grid code is selected in VEConfigure,​ then the backfeed relays are tested every time before connecting to the mains.
  
-The other tests that raise Error 11 when they fail concern the Ground Relay. During inverter operation, disconnected from mains, the relay is continuously tested to be closed. And it is tested to open properly during switchover to mains. The ground relay tests are always performed: with or without a configured grid code. Unless the relay is disabled in VEConfigure. See product manual for more information regarding the ground relay.+Ground relays are also tested and can trigger an Error 11.

The ground relay tests are always performed: with or without a configured grid code. Unless the relay is disabled in VEConfigure.

There have been various VE.Bus error 11 related improvements in the firmware. This may correct the error, and if it does not, it will provide additional information to assist troubleshooting.
  
-Step 2: Verify that system is properly wired to your installation and your local codes. Remember to check the earth connection on the unit AC input. Earth should be grounded according to your local grid rules. Do not connect Earth to Neutral ​on the unit. This will create a safety hazard and will prevent RCD devices from working. Contact ​licensed electrician if in doubt. ​+Step 2: Verify that system is properly wired to your installation and your local codes. Remember to check the earth connection on the unit AC input. Earth should be grounded according to your local grid rules. Do not connect Earth to Neutral ​in the unit itself. This will create a safety hazard and may prevent RCD devices from working. Contact ​another ​licensed electrician if in doubt. ​
  
-Step 3: Disconnect the wiring from the ACout terminals on each inverter/​charger. Which, in case of a parallel or three phase system, isolates the ACout connections for each unit. If the system then starts normally there might be a problem with a connected load (e.g. a leakage between load neutral and ground).+Step 3: Disconnect the L and N wiring from the ACout terminals on each inverter/​charger. Which, in case of a parallel or three phase system, isolates the ACout connections for each unit. If the system then starts normally there might be a problem with a connected load (e.g. a leakage between loadneutral and ground).
  
-Step 4: Check your Neutral-out connection. ​There should be no external connection ​from Neutral-out to Neutral-in or to Earth. ​If your local grid code requires ​bypass ​between Neutral-in and Neutral-out, ​contact your Victron representative for a solution.+Step 4: Check your Neutral-out connection. ​In most cases there should be no external connection ​between ACin-Neutral ​to ACout-Neutral, ​or to Earth. ​ 
 + 
 +In Australia, it is possible if required to install with connection ​between Neutral-in and Neutral-out ​using AS4777.2:​2015. Select either design configuration in the grid code section while programming the MultiPlus-II with firmware 466 and above. After configurationalways confirm that the system is safe with routine electrical safety checks in both modes (eg test RCD operation with AC input connected and disconnected).
  
 Step 5: Neutral and line input might be inverted. Check the input connections,​ swap them if needed and retry. In this case, “Failing step: 8” will show. Step 5: Neutral and line input might be inverted. Check the input connections,​ swap them if needed and retry. In this case, “Failing step: 8” will show.

-  * PE2 open error or GND Relay Error: check that AC-out Neutral is not wired to Ground. Short circuiting them is not allowed. Also, check that there is no leakage between Neutral and ground, for example because broken consumer.
