Mastervolt Lithium Inverter/Chargers

Empower your adventures with Mastervolt Lithium Inverter/Chargers, the pinnacle of integrated power solutions tailored for lithium-ion (LiFePO4) batteries. Merging a high-efficiency pure sine wave inverter, advanced multi-stage battery charger, and intelligent AC transfer switch into one lightweight, compact unit, these combis deliver flawless 120V AC power for demanding loads – from sensitive avionics to high-draw appliances – while rapidly recharging your batteries from shore, generators, or integrated solar inputs. The Mass Combi Ultra and CombiMaster series shine with models like the 12V/2500W-100A and 24V/3000W-150A (120V versions), offering extended surge capacity up to 6000W for surge-heavy starts like air conditioners or winches. Mastervolt's proprietary 3-step+ charging technology ensures optimal profiles for lithium, reviving deep discharges and extending battery life, with temperature compensation for superior efficiency in harsh environments. Maintain full output even at 104°F (40°C), and operate reliably from -4°F to 140°F (-20°C to 60°C). Key innovations include Power Assist to boost limited grid/generator supply from batteries (preventing fuse trips), separate inputs for grid and generator, and an optional built-in MPPT solar charge regulator for hybrid renewable setups. Seamless MasterBus networking enables stacking up to four units for scalable power to 12kW, parallel or split-phase configurations, and remote monitoring via NMEA 2000 or CZone digital switching – track consumption, voltage, and alerts from your app or panel. GMDSS-compatible options add safety for commercial marine ops. Engineered for extremes, these units feature conformal-coated boards for corrosion resistance, ignition protection, and compliance with UL 458, ABYC, and CE standards. The ultra-compact design (under 20 lbs for many models) fits tight RV bays or boat compartments, with vibration-proof mounting and zero-maintenance reliability. Whether outfitting a luxury yacht, full-time RV, or remote off-grid retreat, Mastervolt Lithium Inverter/Chargers deliver silent, generator-free independence with unmatched versatility. Backed by robust warranties, they're the smart choice for lithium-savvy users. Discover the lineup and charge your freedom today.
