<h3>Xantrex Technologies: Decades of Mobile Power Innovation</h3><p><strong>Xantrex Technologies</strong> has been engineering reliable power solutions for over four decades. Founded in 1983 as a power supply company, Xantrex expanded its inverter offerings through key acquisitions of Heart Interface, Statpower Technologies, and Trace Engineering in the &apos;90s and 2000s — building the deep expertise in power electronics that defines the brand today. Xantrex is now part of Mission Critical Electronics (MCE), a leader in the development of innovative solutions for power conversion, energy storage, power generation, and shore power connectivity.</p><p>Xantrex designs, manufactures, and markets power products used when on the move to provide auxiliary or emergency power. Xantrex products are used in a variety of applications in the RV, marine, military, construction, EMS, bus, work service vehicle, and commercial truck markets. Whether you&apos;re a weekend boater, a full-time RVer, or a fleet operator keeping work trucks on the road, Xantrex has purpose-built solutions designed for your environment.</p><h3>A Complete Mobile Power Ecosystem</h3><p>What sets Xantrex apart is its ability to cover every stage of the mobile power chain — from energy generation and storage to conversion and management. At the heart of the lineup are <a href="/7660-xantrex-technologies-inverters-200588">Xantrex inverters</a> and <a href="/7660-xantrex-technologies-power-inverter-14297">power inverters</a>, which convert DC battery power into the clean AC electricity needed to run appliances, electronics, and tools onboard. Xantrex true sine wave inverters mimic utility grid power for smooth operation of appliances like microwaves and computers.</p><p>Pairing seamlessly with those inverters are Xantrex&apos;s <a href="/7660-xantrex-technologies-battery-charger-14307">battery chargers</a>, engineered for efficiency and battery longevity. Xantrex battery chargers stand out for their microprocessor-controlled, multi-stage charging process, which ensures optimal battery performance and longevity. For users who want a fully integrated approach, Xantrex inverter/charger combos fold the inverter, charger, and transfer switch into a single compact unit — a major advantage in space-constrained RV and marine installations.</p><p>Energy storage is covered by Xantrex&apos;s growing lineup of <a href="/7660-xantrex-technologies-batteries-200137">lithium-ion batteries</a>. Xantrex manufactures a variety of lithium-ion batteries for mobile applications including marine, RV, truck, and specialty vehicles, offered in popular Group 31 and Group 27 sizes. Around 2017, Xantrex started offering solar panels and lithium batteries, rounding out products for energy production, storage, and conversion. Completing the ecosystem, Xantrex solar panels allow users to harness the sun for off-grid or supplemental charging — tested to produce 70% of normal power in severely shaded conditions compared to almost no power from leading competitor technologies.</p><h3>Built to a Higher Standard</h3><p>With more than three decades of design, engineering, and manufacturing experience, Xantrex power solutions offer an enviable mix of advanced technology and unmatched bankability. Xantrex ensures its products are put through extensive reliability testing and certifies its products to comply with various regulatory standards to meet or exceed applicable requirements for safety, quality, efficiency, and environment. Many RV manufacturers, boat builders, and specialty vehicle manufacturers exclusively use Xantrex batteries and other solutions for their power needs.
