Victron Interface MK2-USB (VE.Bus to USB) — Legacy, for Phoenix Charger
Free shipping over $49
60-day hassle-free returns
The legacy VE.Bus-to-USB interface — kept for older Phoenix Chargers. The MK2-USB connects a Victron VE.Bus device to a computer over USB so you can configure it and update firmware with Victron's VE Configure tools. It has largely been replaced by the MK3-USB — Blue Marine stocks the MK2-USB mainly for older Phoenix Charger units that still require it.
- What it does. Bridges a VE.Bus port to a PC via USB for configuration and firmware updates using VE Configure.
- Check this is the one you need. For a MultiPlus, MultiPlus-II, Quattro, EasySolar, EasyPlus, or any current VE.Bus inverter/charger, use the MK3-USB instead — it's the current interface and supports those units. Reach for the MK2-USB only when an older Phoenix Charger calls for it.
- Galvanically isolated. Protects your computer from the DC system during configuration.
- Genuine Victron Energy interface — full 5-year Victron warranty.
- Not sure which interface fits your gear? Our ABYC-certified Advisors can confirm before you buy.
For current VE.Bus products, see the MK3-USB; for VE.Direct devices like MPPTs and battery monitors, see the VE.Direct to USB interface. Book a system consultation if you'd like a hand.
