Magnum Energy 2000 Watt 12V Pure Sine Inverter Charger MS2012



Availability: Out of stock SKU: MS2012 Category:


The MS Series Inverter/Charger is a pure sine wave inverter designed specifically for the most demanding mobile and off grid applications. The MS Series is powerful, easy-to-use, and best of all, cost effective. Install the MS Series in four easy steps: simply connect the inverter’s output to your distribution circuits or electrical panel, connect your shore power cable (AC) to the inverter’s easy-to-reach terminal block, connect the batteries, and switch on the power.

There are two modes of operation associated with an inverter/charger:


Inverter Mode:

  • Direct current (DC) from the vehicle’s batteries is transformed into alternating current (AC) for use with you household electrical appliances.


Charger Mode:

  • Alternating current ( AC) is taken directly from shore power (or other AC sources) and passed directly to your household appliances . At the same time, the incoming AC is also converted to DC to recharge the vehicle’s batteries.
