   - This error often follows VE.Bus Error 1. Solution: solve the cause for VE.Bus Error 1. Note that when using an older CCGX (version before v1.40), ​ it can be that the first error is not reported on the Alarm log on VRM. So even when it only lists VE.Bus Error 3, it can very well be that that error was preceeded by VE.Bus Error 1.   - This error often follows VE.Bus Error 1.

-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 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. 
 + 
 +Ground relays are also tested and can trigger an Error 11. During inverter operation, disconnected from mains, the relay is continuously tested to be closed. And it is tested to open properly ​during switchover to mainsThe 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. 
 + 
 +=== Steps to take: ===
  
-The relays are tested when a grid code is selected ​in VEConfigureWhen the grid-code is set to Nonethe tests are not performed.+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 firmwareThis may correct ​the errorand if it does not, it will provide additional information to assist troubleshooting.
  
-When VE.Bus error 11 shows, either ​the back-feed relay test, ground relay test, or measurement redundancy tests has failedThe tests are automatically performed every time before connecting ​to mains.+Step 2: Verify that system is properly wired to your installation and your local codesRemember to check the earth connection on the unit AC inputEarth 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
  
-The three root causes ​of the error can be (from most common to least common):+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 load, neutral and ground).
  
-1) In most cases, when you see Error 11, its due to an installation error:\\  +Step 4Check your Neutral-out connection. ​In most cases there should be no external connection between ​ACin-Neutral to ACout-Neutral,​ or to Earth. ​
-  * 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). +
-  * 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 Australia: ​contact your distributor.+In Australia, it is possible if required to install with a 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 configuration,​ always confirm that the system is safe with routine electrical safety checks in both modes (eg test RCD operation with AC input connected and disconnected).
  
-3) Hardware defect; contact your distributor for a replacement.+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.

-Error 17 will only appear ​on slavesYou'll see it when its phase-master ​is no longer ​communicating ​on the VE.Bus network.+Steps to take: 
 +  - In some cases this error can be seen temporarily while using Remote VEConfigure to write a new configuration. \\ __Solution__:​ ignore the error; the system ​will recover by itself. 
 +  - The most likely cause is a cable-related communication issue on the VE.Bus network: \\ __Solution__:​ First check the network cables sockets. If that doesn't solve it, replace all network cables, including the cable to the [[venus-os:start|GX Device]]. Make sure to also inspect the female RJ-45 sockets, instead of only the cabling: sometimes badly mounted RJ45 cable connectors prevent the spring-contacts in the female RJ45 connectors on the Multis to properly make contact. Make sure to machine-made cabling. Do not use self-crimped cables. 
 +  - DC fuse blown. In this case, all units can in some situations seem fine and work well as long as mains is available. And then when there is no longer ​AC available ​on the input (mains fails or generator is stopped) the non powered units are disconnected from the system\\ __Solution__:​ Check the fuse in all units; replace the broken one. 
 +  - Update firmware and Assistants of the inverter/​chargers. And of the GX Device. \\ __Solution__:​ [[updating_firmware:​updating_ve.bus_products|Update the Inverter/​charger firmware]] - [[assistants:​how_to_update_an_assistant|Update the Assistants]] - [[ccgx:​firmware_updating|Update the GX Device firmware]].

 +=== 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.
  
-  * In some cases this error can be seen temporarily while using Remote VEConfigure ​to write new configuration. +=== Unable ​to solve it? ===

Depending ​on the situation, they might advice to replace the [[venus-os:start|GX device]] ​and the inverter/​chargersWe advise ​to first replace cablesand if that doesn'​t help then thereafter ​only the GX device at first, since that is less work than replacing ​the inverter/​chargers.
