<h3>About Magnum-Dimensions</h3><p>Magnum-Dimensions has established itself as one of the most respected names in mobile and stationary power conversion. Born from a legacy of innovation rooted in the Pacific Northwest, <strong>Magnum-Dimensions</strong> grew out of decades of inverter engineering expertise and has since expanded into a comprehensive portfolio of DC-to-AC power solutions trusted by professionals across a wide range of demanding industries.</p><p>The brand operates under the umbrella of Sensata Technologies, which united the Magnum Energy and Dimensions Inverter product lines into a single, cohesive brand. Today, Magnum-Dimensions products are manufactured in Everett, Washington and St. Paul, Minnesota, with UL and Intertek-certified production underpinning the quality assurance that field technicians, fleet managers, and off-grid enthusiasts have come to rely on.</p><h3>What Magnum-Dimensions Makes</h3><p>At the heart of the Magnum-Dimensions catalog are its industry-leading <a href="/11270-magnum-power-inverter-14297">power inverters</a>. These units convert DC battery power into clean, usable AC electricity, allowing users to run air compressors, drills, air conditioners, microwaves, computers, and virtually any AC-rated equipment wherever a proper DC power source is available. The lineup spans both pure sine wave and modified sine wave designs, with output ratings ranging from 300 watts all the way up to 12,000 watts in single and three-phase topologies, and DC input compatibility from 12 to 300 volts. Whether you&apos;re outfitting a recreational vehicle, a marine vessel, a utility truck, or a remote off-grid installation, there&apos;s a Magnum-Dimensions inverter engineered for the job.</p><p>Complementing the inverter lineup is Magnum-Dimensions&apos; advanced <a href="/11270-magnum-battery-charger-14307">battery charger</a> technology. Many of the brand&apos;s inverter/charger combo units feature power factor correction techniques — an innovative approach that improves charging efficiency across both sine wave and modified sine wave platforms. These integrated charger systems support a wide variety of battery chemistries, including Flooded, Gel, AGM, and Lithium Iron Phosphate (LFP), making them highly adaptable to modern energy storage setups.</p><h3>Key Product Series</h3><ul><li><strong>MS Series:</strong> A flagship pure sine wave inverter/charger line purpose-built for demanding mobile, backup, and off-grid applications, available in 12V, 24V, and 48V configurations.</li><li><strong>MMS Series:</strong> An economical pure sine inverter/charger solution for smaller mobile power needs, known for its lightweight, versatile design.</li><li><strong>MS-PAE Series:</strong> Magnum-Dimensions&apos; most robust renewable-energy-focused inverter/charger, with outputs reaching up to 17,600 watts.</li><li><strong>MSH Series:</strong> A hybrid inverter/charger that adds &quot;Load Support&quot; functionality, allowing incoming AC to synchronize with the inverter output for seamless power blending.</li><li><strong>MMP &amp; MP Panel Systems:</strong> Pre-wired panel solutions that simplify installation and system integration for both residential and mobile setups.</li></ul><h3>Industries Served</h3><p>Magnum-Dimensions products are widely deployed across recreational vehicles, marine applications, corporate and utility fleets, telecommunications, military operations, and renewable energy systems. This breadth of application speaks to the engineering rigor behind every product — these are not consumer-grade devices, but professional-class power systems designed to perform reliably under harsh, real-world conditions.</p>

Product Details

The Magnum MS2812-L is a 2800-watt, 12-volt pure sine wave inverter/charger engineered for the most demanding mobile, off-grid, and backup power applications. Combining robust inverter output with a high-capacity 125-amp Power Factor Corrected (PFC) battery charger in a single unit, the MS2812-L delivers reliable, clean power wherever it is needed — from RVs and marine vessels to emergency vehicles and renewable energy systems.

Key Features:

  • Pure Sine Wave Output: Produces clean, utility-grade AC power safe for sensitive electronics, motors, and appliances
  • 2800W Continuous Output at 25°C with a 5000W 30-minute surge capability
  • 125-Amp PFC Charger: Uses 25–30% less AC current from a generator than standard chargers, reducing fuel consumption and runtime costs
  • Five-Stage Charging: Bulk, Absorb, Float, Equalize (requires remote), and Battery Saver modes for optimized battery health
  • Battery Profile Presets: Supports Lithium Iron Phosphate (LFP), Gel, Flooded, AGM1, and AGM2 profiles via compatible remote controls
  • 15 ft Battery Temperature Sensor: Included standard for accurate temperature-compensated charging (0–50°C range)
  • Variable-Speed Internal Cooling: Dual 92mm brushless DC fans with 0–120 CFM airflow for quiet, efficient thermal management
  • Multiple Protection Circuits: Overcurrent (dual overlapping circuits), overtemperature (transformer, MOSFETs, and battery), and input voltage protection
  • Corrosion-Resistant Construction: Conformal-coated PCBs, powder-coated chassis and top cover, and stainless steel fasteners
  • Versatile Mounting: Can be shelf-mounted, bulkhead-mounted, or installed upside down; lightweight aluminum base and cover reduce noise
  • Connectivity: RS-485 communication port for network expansion and a dedicated remote control port
  • On/Off Switch: Inverter-mounted with easy-to-read LED status indicator
  • Transfer Relay: 50-amp transfer relay capability supporting 120V/30A or 240V/60A service
  • Inverter Efficiency: Up to 88% peak efficiency; 30W typical no-load draw

Certifications & Compliance:

  • ETL Listed to UL/cUL 458 for mobile applications
  • ETL Listed to UL 1741 and CSA C22.2 #107.1-01 for renewable energy installations
  • Meets KKK-A-1822E standards for emergency vehicle use

Warranty: Backed by a 3-year (36-month) limited warranty, extendable to 5 years when installed as part of a Magnum MMP or MP panel system.

HAVEN'T HAD TIME TO INSTALL YET SO I SURE HOPE IT WORKS

Easy payment for Apple Pay

It would have been better if you listed the dimensions so hopefully it fits
