The Magnum Energy MS2012-20B is a 2000W 12VDC pure sine wave inverter/charger designed for demanding mobile, backup, and off-grid applications. Its pure sine wave output helps support sensitive electronics, appliances, and other AC loads that require clean 120VAC power.
The MS Series is built for practical system integration with a power factor corrected charger that uses less generator power than a standard charger, helping reduce AC current draw during battery charging. When paired with compatible Magnum remote controls, users can select battery profile presets for common battery types, including LFP, Gel, Flooded, AGM1, and AGM2.
This MS2012-20B version is the breakered output model with two 20A output breakers, making it a fit for installations that require integrated branch output protection in a 12V inverter/charger system.
