 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.  Step 4: Check your Neutral-out connection.

 +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).
  
 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.

   - 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.   - The most likely cause is a cable-related communication issue on the VE.Bus network: \\ __Solution__: First check the network cables sockets.

   - 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.   - DC fuse blown.

 +==== Error 19 - Slave does not have AC input! ====
 +
 +Common cause - System is configured with multiple synchronised inverter/chargers but AC input (e.g. from a generator) is only connected to one of the Inverter/Chargers.
 +
 +Solution: Either connect the AC input to all units, or change the configuration of the synchronised units in VE.Bus System Configurator (note not VEConfigure), and disable the 'Switch as Group' Function. This setting will allow only a single Inverter/Charger to charge without error. Note this setting is not adjustable in an ESS system.
