Victron Interface MK2-USB Adapter

The Victron Interface MK2-USB is a dedicated diagnostic and configuration tool designed to bridge the gap between your legacy Victron Phoenix Inverters/Chargers and a Windows PC. By converting the device's RS-485 data port into a standard USB connection, this interface allows you to fully customize device parameters, monitor performance, and update firmware using Victron’s free VEConfigure and VEFlash software tools.

This adapter is specifically engineered for the older generation of Phoenix products utilizing the RS-485/VE.9bit protocol. Whether you are adjusting charging profiles or configuring inverter setpoints, the MK2-USB provides a reliable, plug-and-play link. Note: This unit is intended for the legacy Phoenix RS-485 series. For modern VE.Bus products like the MultiPlus-II or Quattro, please use the Interface MK3-USB adapter instead.
