Victron VE.Bus to USB MK3 Interface Cable: Professional Configuration Tool for Victron Energy Systems

Reliable USB to VE.Bus Connectivity for MultiPlus, Quattro, and EasySolar

The Victron VE.Bus to USB MK3 Interface Cable (ASS030140000) provides a direct, stable link between your computer’s USB port and the VE.Bus communication port on compatible Victron devices. This interface enables precise configuration, firmware updates, and system monitoring using Victron’s official software suite, including VictronConnect and VEConfigure. It is an essential accessory for installers, system integrators, and advanced users managing Victron MultiPlus, Quattro, EasySolar, and other VE.Bus-enabled products.

Unlike generic USB-to-serial adapters, the MK3-USB is purpose-built for the VE.Bus protocol, ensuring reliable data transfer and full compatibility with Victron’s proprietary communication. This reduces the risk of configuration errors, communication dropouts, and potential damage to sensitive electronics. The integrated interface box features a moulded strain relief and a robust RJ45 socket, designed to withstand frequent use in workshops, marine environments, and off-grid installations.

Key Features

  • Direct USB-A connection to Windows, macOS, and Android devices (OTG cable required for Android)
  • RJ45 VE.Bus port for secure, industry-standard LAN cable connection to Victron equipment
  • Compatible with VictronConnect for streamlined configuration and firmware updates
  • Durable moulded strain relief protects internal wiring from bending and fatigue
  • Compact interface box with clear labelling for easy identification in complex setups

Broad Compatibility Across the Victron Ecosystem

This interface cable works with a wide range of Victron products that feature a VE.Bus communication port, including:

  • MultiPlus and MultiPlus-II inverter/chargers
  • Quattro inverter/chargers
  • EasySolar and EasyPlus all-in-one systems
  • ECOmulti units
  • VE.Bus BMS V2
  • Select Inverter models with VE.Bus

For connection, a standard straight RJ45 UTP cable (patch lead) is required between the MK3-USB and the Victron device. Using an industrially manufactured cable is recommended to maintain signal integrity and avoid intermittent faults.

Why Choose the Genuine Victron MK3-USB?

Third-party or generic USB-to-RJ45 adapters often lack the necessary protocol handling for VE.Bus, leading to failed firmware updates, incomplete configuration, or unrecognised devices. The genuine Victron MK3-USB eliminates these risks by providing a fully integrated, tested solution. It supports all VE.Bus commands and ensures that critical settings—such as charger voltages, inverter thresholds, and grid interaction parameters—are applied accurately.

For mobile installers and field technicians, the compact design and USB bus-powered operation mean no external power supply is needed. Simply plug into a laptop, connect to the VE.Bus network, and launch VictronConnect or VEConfigure to begin diagnostics or programming.

Software and Platform Support

The MK3-USB is compatible with VictronConnect on Windows, macOS, and Android (iOS not supported). On Android devices, an OTG cable is required to adapt the USB-A plug to micro-USB or USB-C. For advanced configuration, VEConfigure tools are available for Windows, offering deeper access to system parameters. Always download the latest software from the official Victron Energy website to ensure full functionality and security.

Take Control of Your Victron System

Equip your toolkit with the Victron VE.Bus to USB MK3 Interface Cable and unlock the full potential of your Victron energy system. Whether commissioning a new off-grid installation, updating firmware on a marine inverter, or fine-tuning a backup power setup, this interface provides the reliable connection you need. Add it to your order today and experience seamless configuration backed by Victron’s engineering standards.

My Fave Sunscreen
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 6 Ounce (Pack of 2)
I love this sunscreen. I bike ride a lot in the summer and I always bring sunscreen with me because I sweat and need to reapply. If I use a cream, my hands end up wet or greasy and I'm holding the handlbars, etc. So, using a spray is way better for me. I loooooooove the smell of this stuff. It smells of summer! The spray makes it easy to get my back while at the beach and while it's not insanely waterproof, it's certainly water resistant and lasts a long time. I like the SPF 50, because less isn't enough for me. They say going higher than 50 isn't any better, so I stick with 50 as my "go to." Buying the duo, as sold here, makes it a good value. Buying this product at a local drug store would cost twice as much. I easily go through both cans in a single summer.

IT WORKS
Style: SPF 50
I used this on my trip to Jamaica and it worked great. I was in the sun for hours and it kept me from getting any lines. I did reapply after going in the water and when I was feeling really hot. However, I did get burned on the top of my feet as the sand was all over them so I couldn't put sunscreen on them. Lesson learned put lots of sunscreen on your feet prior to arriving to the beach. It does stay on slightly when you go in water. You will see a faint white cast on your skin, but nothing extremely noticeable. Otherwise it rubs in really well and there is no white cast, (only after you go in water will you notice it slightly). If your main purpose is to protect your skin, then this is your friend. It's reef safe and does have safer active ingredients that I feel more comfortable using on my skin. Very happy. I used about 3/4 of the bottle for 3 days of use, this includes reapply applications. So if you have a family you may need to take more than one bottle for a long trip and it's a bit more pricey, but better ingredients typically do cost more.

Bought 2nd time
Style: SPF 30
I am loyal to the Hawaiian Tropic brand because they have a wonderful scent. Not like the typical sunscreen smell, but fragrant and subtle. This sunscreen does keep my skin protected and I use it almost everyday living in sunny Las Vegas. Doesn't leave a white film and blends into my skin. It is matte, doesn't feel oily. I prefer the 30 SPF for daily use. This is my second purchase and just want a smaller size for travel. But I'll just squirt some into an empty travel sized bottle because I enjoy it for my everyday lotion.

One of my favorites because it doesn't sting my eyes
Style: SPF 50
This was my first time purchasing this from Amazon though I've bought this product elsewhere before. This is a sunscreen I come back to because I can use it on my body and it works relatively well on my face as well. It is hydrating and can give a matte-ish looking finish although on my face I'd say it leaves more of a dewy look because I put moisturizer on prior to applying. I've seen a few reviews mention there is pilling when applying to the face and while I've had that happen it's normally only during the day when I reapply. I think that first thing in the morning I don't really have that issue because of the moisturizer I put on before- I let the moisturizer soak in a bit before going in with the sunscreen. My favorite thing about this sunscreen is that it doesn't sting my eyes, I've worn it out on 90+ SoCal heat and it has not stung my eyes- there's been numerous sunscreen I like on my face but don't repurchase because even mid-80"s heat causes them to run and both sting and blur my vision. As for my giving this a 4 rather than a 5 it is because it leaves a mild white cast after I apply it norming and reapplying throughout the day. The mild white cast does eventually go away but it does take some time, though that is the one downsides I am glad that I'm at least not forced to sport a ghost-ish face all day. In all honestly, the cast is only mild when compared to others like the New "Sheer" Bluelizard SPF 50 face lotion, among others. I'm a little jealous of others who say they don't have a white cast at all but different products react differently with different people so I know it might just be a "me thing." Overall this is one of the sheer and non-tinted sunscreens I am happiest with and will repurchase again as needed unless I stumble onto that unicorn 50 broad spectrum SPF, cast free, no eye burning/ irritating, and reasonably priced and sized sunscreen =)

Non-greasy, doesn’t cause irritation to my sensitive skin or cause breakouts, good sun protection, holds up to sweat, smells terrific, fair price. I just wish there were multiple spf options. I have already bought more.
