Magnum MS2812-L 2800W 12V Pure Sine Wave Inverter Charger with 125 Amp PFC

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.
