The Magnum Energy MSH3012M is a 3000W 12VDC pure sine wave hybrid inverter/charger designed for applications that need clean AC power, battery charging, and the ability to support larger loads from smaller generators or limited shore power. Its pure sine wave output helps power sensitive electronics, appliances, and other 120VAC loads.
Unlike standard inverter/chargers that rely on either incoming AC power or battery power, the MSH-M Series uses true hybrid technology to combine energy from both sources. When extra AC input power is available, the inverter/charger can recharge the batteries. When loads require more than the AC input can supply by itself, it can supplement the AC source with battery power.
Battery profile presets are available when used with compatible ME-RC or ME-ARC remote controls, allowing setup for common battery types including Lithium Iron Phosphate, Gel, Flooded, AGM1, and AGM2. LFP battery profile support is available through the ME-RC remote.
