About Mastervolt

Founded in Amsterdam in 1991, Mastervolt has spent more than three decades engineering power management solutions for the world's most demanding off-grid environments. From the open ocean to remote wilderness campsites, Mastervolt products are trusted by mariners, RV travelers, utility crews, emergency responders, and commercial vehicle operators who simply cannot afford a power failure.

What sets Mastervolt apart is its systems-level approach. Rather than offering individual components in isolation, Mastervolt designs its entire product ecosystem — chargers, monitors, inverters, and relays — to work seamlessly together. This integration means less troubleshooting, more consistent performance, and a power setup that grows with your needs.

A Legacy of Marine-Grade Engineering

Mastervolt built its reputation on the water, where vibration, moisture, and unpredictable power sources put equipment to the test daily. That marine-grade pedigree carries over to every product category the brand offers. Whether you're fitting out a blue-water cruiser, a Class A motorhome, or a service van, Mastervolt components are engineered to handle harsh conditions with reliability and precision.

The brand has also been an early adopter of Lithium Ion battery technology, offering customers the benefits of lighter weight, faster charging, longer cycle life, and greater usable capacity compared to traditional lead-acid systems. This commitment to advancing the technology — not just selling it — is a hallmark of the Mastervolt brand.

Core Product Categories

At the heart of any Mastervolt system is intelligent charging. The brand's lineup of Battery Chargers covers everything from compact onboard units to multi-bank chargers capable of managing complex battery configurations across multiple chemistries simultaneously. Smart charging algorithms protect battery health and maximize lifespan.

Keeping a close eye on your power reserves is equally important, and Mastervolt's Battery Monitors & Volt Meters give operators precise, real-time insight into state of charge, current draw, and remaining run time. Accurate monitoring is the difference between a confident offshore passage and an unexpected situation at sea.

Rounding out the core system, Mastervolt's Battery Isolators & Voltage Sensitive Relays ensure that charging sources are distributed intelligently across battery banks — protecting your start battery while maximizing charge to your house bank, without manual switching or the risk of draining critical reserves.
