Victron power systems for vessels, wired to ABYC standards

Vibration, salt air and no one to call offshore make a boat the hardest place to wire. We design and install Victron DC and AC systems for commercial vessels and yachts — built to ABYC standards with tinned marine cable and UL listed distribution.

ABYC-certified Victron marine installs

Designed and wired to American Boat & Yacht Council standards by an ABYC-certified technician — Victron systems, lithium repowers and helm integration, done to code.

ABYC certified

To ABYC E-10 and E-11 — tinned cable, correct overcurrent protection, restraint and ventilation.

Victron installs

MultiPlus-II, Quattro, Cerbo GX, Lynx distribution, Orion XS, SmartShunt and SmartSolar MPPT.

Lithium upgrades

Lead-acid to LiFePO₄ — BMS integration, alternator protection and correct charge control.

Integrations

Cerbo GX onto your NMEA 2000 helm display, VRM remote monitoring, and Node-RED logic.

Who we build for

Two very different boats, one standard of work

Whether the vessel earns its keep or takes the family out on weekends, the wiring behind the panel is held to the same practice.

Commercial vessels

Workboats, charter and tour operators, research and survey vessels, fishing boats, and tenders. Uptime is revenue, so the priority is a system that keeps running and that a crew can diagnose without a specialist onboard.

  • Silent hotel loads at anchor without running the genset
  • Redundancy and clear isolation for troubleshooting underway
  • Labeled, documented panels the crew and the next yard can follow
  • Remote monitoring so problems surface before they strand you

Pleasure yachts

Sail and power, coastal cruisers and liveaboards. The goal is a quiet boat — air conditioning, induction cooking, and a full night at anchor without the generator running or the neighbours complaining.

  • Lithium house banks sized to a real night on the hook
  • High-output alternator and DC-DC charging that respects the BMS
  • Shore power that handles 30A, 50A, and the dock you didn't plan for
  • System data on the MFD at the helm, not just a phone app
Built to ABYC

How it works

ABYC publishes the U.S. safety standards for boat electrical systems. Surveyors reference them and insurers ask about them — here's how we wire to them on every job.

ABYC E-11

Tinned, correctly sized cable

Stranded, tinned marine copper sized for voltage drop — bare copper wicks salt and corrodes out of sight.

ABYC E-11

Protection at the source

Fusing within inches of the bank, not at the far end of the run — and ignition-protected gear in fuel spaces.

Workmanship

Crimped, not soldered

Marine-rated crimp terminals sealed with adhesive-lined heat shrink. Solder turns a vibrating wire into a break point.

ABYC E-10

Batteries & lithium

Banks strapped down and protected, with the BMS wired into every charge source and cold-weather charge limits set.

ABYC A-31 · A-28

Shore power & isolation

Properly mounted inverter/charger and a galvanic isolator or isolation transformer, so stray current can't eat your running gear.

Handover

Labelled & documented

ABYC colour codes, every circuit labelled, and an as-built wiring schedule so the next person can read the boat.

What goes in the boat

Name-brand components, no substitutions

The cheapest part of any marine electrical job is the wire and the terminals. It is also the part that fails first when someone economises. We do not.

Ancor marine cable

Tinned, finely stranded, marine-grade boat cable — UL 1426 listed and built for a wet, vibrating, salt-laden environment. Correct gauge for the load and the run length, sized for voltage drop rather than just ampacity.

Plus Ancor heat-shrink terminals, adhesive-lined shrink, chafe protection and cable clamps from the same range.

Blue Sea Systems distribution

AC and DC distribution panels, busbars, fuse blocks, battery switches, and ANL/MRBF/Class-T fusing. UL listed components, with ignition-protected parts specified wherever the space calls for them.

Circuit-by-circuit breakers and engraved labels, so every load is identified and individually protected.

Victron Energy

MultiPlus-II and Quattro inverter/chargers, Cerbo GX and GX Touch, Lynx distribution, Orion XS DC-DC, SmartShunt, SmartSolar MPPT, and Victron isolation transformers — one ecosystem that actually talks to itself.

We are a Victron integration specialist first; the marine work is that expertise applied to a hull.

MFD integration

Your power system on the chartplotter you already own

Battery data belongs at the helm, not buried in a phone app you have to go find. A Cerbo GX bridges the whole Victron system onto your NMEA 2000 backbone, so state of charge and AC status sit on the same screen as depth, speed and chart.

How it connects

The GX device is the translator. Everything Victron — inverter/charger, MPPT controllers, SmartShunt, tank and temperature senders — reports to the Cerbo over VE.Bus, VE.Direct and VE.Can. The Cerbo then publishes that data onto NMEA 2000 through a single drop cable into your existing backbone.

  • One cable, not a parallel network. The Cerbo's VE.Can port connects to the N2K backbone with a VE.Can-to-NMEA 2000 micro-C drop — no second display, no separate wiring run
  • Correct termination and power budget. A backbone needs terminators at both ends and a load-equivalent count that stays within spec — the most common reason a new device "doesn't show up"
  • Instances set deliberately. Battery, DC and tank instances are assigned so two banks or three tanks stay distinct on the display instead of fighting over the same slot
  • Configured, labelled and handed over. We set it up on your MFD, name every field in plain language, and show you where to look when something changes

What shows up on the display

A typical install puts these right on your chartplotter:

Exact fields vary by display. GX Touch and VRM show the full picture.

Works with your chartplotter

NMEA 2000 is an open standard — these are the displays we integrate with most:

Some displays can also run Victron's app — we'll tell you which suits yours.

And anywhere else

The Cerbo sends everything to Victron's VRM portal, so alerts reach your phone:

Latest firmware · Venus OS 3.70

New in Venus OS 3.70, and what it means on your boat

Victron's February 2026 GX firmware landed squarely in the marine column. We build these in on new installs and retrofit them to systems already aboard.

Switching from the helm

Deck lights, pumps and the water heater — viewed and operated straight from the chartplotter you already use.

Alarms on the NMEA 2000 network

A low bank, lost shore power or an inverter fault now shows up as an alert at the helm — not buried in an app.

Cell-level battery monitoring

With a Lynx Smart BMS NG, the GX shows every battery down to per-cell voltage and temperature — the difference between a diagnosis and a guess.

Plus electric-propulsion gauges, Shelly & EmpirBus switching, new tank sensors and Node-RED virtual switches — see Victron's Venus OS 3.70 release notes. Ask about updating your system →

Scope of work

Refit, repower, or a new build

We take on the whole electrical scope or the part of it you need, and we are just as willing to survey what is already aboard and tell you honestly what should stay.

Lithium house bank conversion

Moving off lead-acid properly — LiFePO⁠₄ bank, BMS integration, alternator protection, charge-source configuration, and the low-temperature charging rules that people skip and then regret.

Inverter & shore power

MultiPlus-II or Quattro installation, transfer switching, shore-power inlets and cordage, galvanic isolation or an isolation transformer, and a panel that handles the dock you actually tie up to.

Panel & distribution rebuild

Replacing tired panels and mystery wiring with Blue Sea distribution, correct fusing, proper busbars, and a labelled, documented layout that a surveyor can follow.

Charging systems

Solar on hardtops and biminis, high-output alternator and DC-DC charging, and Victron MPPT controllers — coordinated so every source charges the bank the way the BMS expects.

Monitoring & integration

Cerbo GX, SmartShunt, tank and temperature senders, NMEA 2000 bridging to the helm, VRM enrollment, and custom Node-RED logic where the boat needs it.

Survey & remediation

An honest look at an existing system against ABYC practice — what is unsafe, what is merely untidy, and what is fine as it is. You get a written punch list, prioritised.
