Description
Magnum Energy MS Series 4,000W 48V Pure Sine Wave Inverter/Charger — built for those who demand reliable, utility-grade power in the most challenging off-grid, mobile, and backup environments.
Key Features
- Pure Sine Wave Output: Delivers clean, stable 120VAC power at 60Hz, safe for sensitive electronics and demanding loads.
- Power Factor Corrected (PFC) Charger: Draws 25–30% less AC current from a generator compared to standard chargers, maximizing efficiency.
- Battery Profile Presets: Supports Lithium Iron Phosphate (LFP), Gel, Flooded, AGM1, and AGM2 battery profiles via compatible remote controls.
- Versatile Mounting Options: Installs on a shelf, bulkhead, or wall with 360° DC connection terminals for flexible, simplified wiring.
- Multi-Stage Charging: Five-stage charging system includes Bulk, Absorb, Float, Equalize, and Battery Saver for optimized battery health.
The MS4048 is engineered for serious power users who need proven performance across backup, off-grid, RV, marine, and mobile applications. With up to 4,000 watts of continuous output and a peak efficiency of 94%, this inverter/charger handles heavy loads without compromise.
Durability is built into every layer of the MS4048. Conformal-coated PCBs, powder-coated chassis, and stainless steel fasteners deliver corrosion resistance in the harshest environments. Dual 92mm variable-speed brushless DC fans provide cooling from 0 to 120 CFM as demands rise.
System integration is seamless with an RS485 communication port, remote port compatibility, and support for accessories including the MagWeb, ME-RC, ME-ARC, and ME-MR remotes. ETL Listed to UL/cUL 458, UL 1741, and CSA C22.2 #107.1-01, the MS4048 meets the stringent standards required for both renewable energy and emergency vehicle installations.
