© 2010 Magnum Energy, Inc.21.0 IntroductionHow an Inverter/Charger WorksAn inverter takes direct current (DC) from your batteries and turnsit into alternating current (AC), like you use at home. With MMSSeries models, it also takes alternating current (when connected toa generator or to shore power) and transforms it into direct currentto recharge your batteries.The two modes of operation associated with this inverter/charger arereferred to in this document as:Inverter Mode: DC from the batteries is transformed into pure sinewave AC for powering your mobile applications.Standby Mode: The unit operates as a battery charger to convertincoming AC power into DC power to recharge the batteries while con-tinuing to pass the incoming AC power directly to the inverter’s outputto power any AC loads.Inverter Applications for Mobile InstallationsInverters can be used to provide power in mobile situations, such asin an RV, truck, or boat. In these applications, the inverter providespower to the AC loads using the energy stored in the batteries andrecharges the batteries when shore power or an onboard generatoris available.Advantages of a Pure Sine Wave vs Modified Sine WaveInverterToday’s inverters come in two basic output waveforms: modified sinewave (which is actually a modified square wave) and pure sine wave.Modified sine wave inverters approximate a pure sine waveform andwill run most appliances and electronics without any problems. Theseinverters are less expensive and, therefore, offer a viable alternativeto more expensive pure sine wave inverters.The output of a pure sine wave inverter is equal to or, in manycases, better than the shore power used in your home. Virtuallyany electronic device will operate from a pure sine wave inverter.Motors run cooler, microwaves usually cook faster, and clocks keepbetter time just to name a few examples. Without compromisingquality or performance, the MagnaSine provides you with all of theadvantages of a pure sine wave inverter at a much lower cost thanmany on the market.Appliances and Run TimeThe MMS Series inverter/charger can power a wide range of householdappliances. As with any appliance using batteries for power, thereis a certain length of time that it can run – this is called “run time”.Actual run time depends on several variables including the size andthe type of appliance, the type of batteries installed in your applica-tion, as well as the battery’s capacity and age. Other factors such asthe battery’s state of charge and temperature can also affect the lengthof time your appliances can run.
