-This error only applies to the MultiGrid, ​MultiPlus-IIEasySolar-II ​and other inverter/​chargers with a dual backfeed relayAs part of grid-code compliance; the device tests verifies that its internal relays function properly.+Error 11 indicates a failed automatic self-test of the MultiPlus-II ​or EasySolar-II ​relaysIt is often a result ​of an installation or wiring issue, though it can also be triggered by a hardware failures.
  
-The relays are tested when a grid code is selected in VEConfigure. When the grid-code is set to None, the tests are not performed.+If a grid code is selected in VEConfigure, then the backfeed relays are tested every time before connecting ​to the mains.
  
-When VE.Bus error 11 shows, either ​the back-feed relay test, ground relay test, or measurement redundancy tests has failed. The tests are automatically ​performed ​every time before connecting to mains.+The other relay tested by Error 11 is the ground relay. It is tested to be closed during inverter operation. 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.
  
-The three root causes of the error can be (from most common ​to least common):+=== Steps to take===
  
-1) In most cases, when you see Error 11, its due to an installation error:\\  +Step 1: Make sure that the units have been [[updating_firmware:​updating_ve.bus_products|updated ​to the latest firmware version]]There have been various VE.Bus error 11 related improvements ​in the firmware.
-  * Please verify ​that the neutral is connected ​to earth on the supply sideIn many countries this is done by the utility ​in the transformer cabinet (a TN network). +
-  * Line should be connected to the corresponding Line input on the inverter/​charger,​ same for Neutral. A swapped connection results in Error 11. +
-  * There should be no external connection between N-out and GND+
  
-2) For Australiacontact ​your distributor.+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 a licensed electrician if in doubt
  
-3) Hardware defect; ​contact your distributor ​for a replacement.+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 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 a bypass between Neutral-in and Neutral-out, ​contact your Victron representative ​for a solution. 
 + 
 +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. 
 + 
 +=== Unable to solve? === 
 +When the error persists after the all above steps, or when any other Failed step or extra explanation shows, then the unit is most likely faulty. Follow the support procedure. 
 + 
 +Make sure to provide a photo of the error details shown on the GX Device menu.

 +==== Error 12 - Config mismatch with 2nd mcu ====
  
 +Some Multi models (e.g. MultiPlus-II) have two microcontrollers.
 +
 +Certain configuration settings, as done with VEConfigure,​ have to be stored in both microcontrollers.
 +In very rare situations it can happen that the stored configurations do not match and that the mismatch cannot be handled automatically. In this case error E12 will be generated.
 +
 +To solve this error, connect the device to VEConfigure 3, verify/​correct the settings and press 'Send Settings'​.
 +
 +Make sure to select the option 'all settings'​ instead of '​modified settings'​.

-If after all above steps you are still experiencing a VE.Bus Error 17, contact your dealer whom will contact Victron repairs; please provide photos of the installation and network cabling. Depending on the situation, they might advice to replace the [[venus-os:​start|GX device]] and the inverter/​chargers. We advise to replace only the GX device first since that is less work.+=== Systems with multiple slaves per phase === 
 +Error 17 can show on one or more slaves in a phase (visible by looking at the LEDs, not on VRM or GX Device). If the slaves can still communicate with each other; then the error will only show on one slave: all slaves that can see on the network that another slave is already showing Error 17 will not show the error as well.
