In the StandbyMode, the unit operates as a Battery Charger to convert the incoming AC power into DCpower to recharge the batteries; and at the same time, automatically closes an internalAC Transfer Relay to pass the incoming AC power directly to inverter’s output to continuepowering the connected electrical appliances.1.2.1 Inverter Applications for Permanent InstallationsAn inverter can be used for backup power in a permanent location that normally uses utility powersuch as a home or office. When the utility power is available, the inverter keeps the batteriescharged. When the utility power fails, the inverter comes on automatically to supply AC power toyour home or office during the power failure. For a home or business, reliable backup power isused to prevent lost computer data or to maintain lights and keep food fresh in the refrigerator/freezer.In some areas, where utility power is not available, this inverter can be used in an stand-alonerenewable power system. The inverter allows AC electrical appliances to be run from the storagebattery bank. When the battery bank becomes discharged, either renewable DC sources (solar,wind or hydro power) can be used to recharge the batteries or a generator can be connected tothe inverter to power the system while the batteries recharge.1.2.2 Inverter Applications for Mobile InstallationsInverters can also be used to provide power in mobile situations, such as in an RV, truck or boat.In these applications, the inverter provides power to the AC loads using the energy stored in thebatteries and recharges the batteries when shore power or onboard generator is available.1.3 Advantages of a Pure Sine Wave vs Modified Sine Wave InverterToday’s inverters come in two basic output waveforms: modified sine wave (which is actually amodified square wave) and pure sine wave. Modified sine wave inverters approximate a pure sinewaveform and will run most appliances and electronics without any problems. These inverters areless expensive and, therefore, offer a viable alternative to more expensive pure sine inverters.The output of a pure sine wave inverter is equal to or, in many cases, better than the utility powerused in your home. Virtually any electronic device will operate from a pure sine wave inverter.Motors run cooler, microwaves usually cook faster and clocks keep better time just to name a fewexamples. Without compromising quality or performance, the MagnaSine provides you with all ofthe advantages of a pure sine wave inverter at a much lower cost than many on the market.The MS Series is built on the same platform as our popular ME and RD Series modified sine waveinverters allowing for an easy upgrade from the original ME or RD Series installation. This standardplatform also helps reduce cost by using standard parts/accessories across many models. AllMagnum accessories such as the Remote Control (ME-RC), Automatic Generator Start - Networked(ME-AGS-N), Battery Monitor Kit (ME-BMK), and network accessories can be used on all ME, RD,and MS Series inverters.••
