Mastervolt — Integrated AC/DC Marine Power Systems

Mastervolt is the premium choice for integrated marine power systems. The MasterBus network architecture connects chargers, inverters, batteries, and monitoring into a single intelligent system — the same approach used on superyachts and high-end production motoryachts from Princess, Sunseeker, and Beneteau. For boats that demand reliability and clean integration, Mastervolt delivers.

Why Mastervolt

Mastervolt's MasterBus protocol gives every component in your AC/DC system a voice — chargers communicate with the battery monitor, inverters know the actual state of charge, and the central display shows everything in one place. The Dutch-engineered hardware is built to commercial marine standards, and the brand's lithium systems (MLI Ultra) include cell-level BMS, communication-ready chargers and inverters, and integration with Bosch generators and ZF transmissions. This is the system you choose when "it just has to work."

Mastervolt System Design & Commissioning

A Mastervolt system is only as good as its design. Proper sizing of chargers and inverters to your AC service, MasterBus topology, battery bank configuration, and shore power management (ChargeMaster vs. Mass Combi vs. CombiMaster) are decisions best made by an experienced installer. Our team is fully trained on the Mastervolt product line — we design, install, and commission complete AC/DC systems including MasterBus programming, lithium configuration, and integration with your existing generator, shore power, and inverter loads.

Mastervolt FAQ

What is MasterBus?

MasterBus is Mastervolt's network. It links chargers, inverters, batteries, and displays so they share data and can be monitored and configured from one place. Adding a single Mastervolt charger does not require it; it matters once you are building a full system.

Can I add a Mastervolt charger to my existing system?

Yes. Mastervolt chargers work on their own. Set the charge profile to match your battery type, and size the charger and its DC cables to the bank. Shop Mastervolt chargers.

Does Mastervolt make lithium batteries?

Yes, the MLI Ultra line, which has a built-in BMS designed to communicate with Mastervolt chargers and inverters over MasterBus. See battery management.
