 This guide should be followed as a pre-cursour to escalation and potential RMA of the GX device and/or the Inverter/chargers. Ideally the advice here should be implemented pre-emptively by Victron Installers  on new installations to prevent these issues occurring in the first place, and to speed up troubleshooting or replacement if VE.Bus errors arise.  This guide should be followed as a pre-cursour to escalation and potential RMA of the GX device and/or the Inverter/chargers.

 Use Manufactured Cables! Always use manufactured cables rather than crimping them onsite. A lot happens at the point of contact. Attempting to crimp cables on site will increase the odds of these issues. The amount of noise to signal goes up dramatically on a less than perfect crimp that visually looks fine and tests ok for continuity. Use Manufactured Cables!

 The network quality counters in the VE.Bus system track the number of frame retransmissions required after a VE.Bus device receives an invalid frame. These counters can be accessed via VRM by adding /diagnostics to the VRM URL for a site. They are reset after you ‘reset' the VE.Bus system on the GX device in the Multi Advanced menu. The network quality counters in the VE.Bus system track the number of frame retransmissions required after a VE.Bus device receives an invalid frame.

-**Small Systems:** In smaller setups with a single unit, delays and retransmissions from a Multi to a GX device may not even have noticeable effects. However, there is a known bug that can cause energy meter counts to stop that will be addressed in a future firmware update.+**Small Systems:** In smaller setups with a single unit, delays and retransmissions from a Multi to a GX device may not even have noticeable effects.
  
 **Large Systems:** In larger configurations with numerous VE.Bus devices, the impact of errors grows exponentially, potentially leading to "Error 3 - Not all, or more than, the expected devices were found in the system.” And alike. Current is also higher, so more interference is created, so more attention is required. **Large Systems:** In larger configurations with numerous VE.Bus devices, the impact of errors grows exponentially, potentially leading to "Error 3 - Not all, or more than, the expected devices were found in the system.” And alike.

-The use of Ferrite core noise suppressing cable clips can also help filter out noise. These are a widely available part and available very cheaply. Some Ferrite core clips are supplied with GX devices and should be attached to the GX power supply cables with a loop to reduce in-line noise and interference. +The use of Ferrite core noise suppressing cable clips can also help filter out noise. These are a widely available part and available very cheaply. Some Ferrite core clips are supplied with GX devices and should be attached to the GX cables to reduce in-line noise and interference. The GX power supply ferrite can be installed with a loop to keep it secure. 
  
 +While not normally necessary, if VE.Bus network errors persist install ferrites on each communications cable in the system at each point of connection. This includes the comms cables between each inverter, between the master inverter and the GX, and the battery comms cables.
