MS Series 2800 Watt 12 Volt Inverter / Charger
The Magnum Energy MS2812 is a 2800W 12VDC pure sine wave inverter/charger designed for demanding mobile, backup, and off-grid applications. Its pure sine wave output provides clean 120VAC power for sensitive electronics, appliances, and other onboard AC loads.
The MS Series includes a built-in power factor corrected charger that uses 25–30% less AC current than standard chargers, helping reduce generator load during battery charging. When paired with compatible ME-RC, ME-ARC, or ME-MR remote controls, users can select battery profile presets for Gel, Flooded, AGM1, AGM2, and Lithium Iron Phosphate batteries.
The MS2812 provides 60A transfer service and a low-frequency topology for robust inverter performance. It is well suited for 12V battery-based systems that need more output capacity than a 2000W inverter/charger while maintaining dependable pure sine wave AC power.
