We are excited to announce the new External Transfer Switch feature for MultiPlus-II.

This feature improves versatility, cost-effectiveness, and reliability, especially in larger systems of 60kVA and above.

Advantages:

• Saves on costs and installation time, especially for large systems that have multiple units in parallel. Eliminating the need to wire each unit by no longer having to wire each unit both on its AC input as well as AC output terminals.
  
  
• Reduce equipment costs by using MultiPlus-II 8kVA, 10kVA and 15kVA in larger, parallel systems, instead of the more expensive Quattro 48/15kVA.  
  
  
• Multis and batteries can be installed up to 20 meters away from the main distribution board, without having to run power wiring back and forth.
  
  
• Eliminates the need for a separate bypass switch.

Key details: 

• Compatible with all MultiPlus-II models rated 5000VA and above.

• Works with both generator-based and grid-tied systems. See this announcement for details on its use in grid-tied systems.

• Requires Venus OS v3.33 and VE.Bus firmware version v551-S99, available on Victron Professional.

• Refer to the MultiPlus-II External Transfer Switch application manual for more information.
