  I’ve come across various family group numbers like 18, 19, 20, 26, and 27 in the context of Victron VE.Bus products. Could someone detail what these numbers signify and how they relate to the product’s specifications?

  The family group numbers in the context of Victron VE.Bus products provide quick reference information about the device’s characteristics, particularly regarding the type of microprocessor and the voltage they operate at.

  Here’s what each number represents:

  • 18: This group number indicates products that do not have VE.Bus capability.

  • 19: This is assigned to VE.Bus products with old microprocessors that operate at 230VAC. So, if you see a firmware with ’19’ at the beginning, it is designed for 230VAC systems with older microprocessor technology.

  • 20: Similar to the ’19’ family but designed for 120VAC. This means that the VE.Bus product has an old microprocessor and is intended for regions with 120VAC electrical systems.

  • 26: This group number is for VE.Bus products that have new microprocessors and operate at 230VAC. Products in this family would be using more recent technology and are compatible with a 230VAC setup.

  • 27: This is the counterpart to ’26’ but for 120VAC systems. It indicates that the VE.Bus product has a new microprocessor and is designed for areas where the electrical systems run on 120VAC.
