The MS-PAE Series also includesa battery charger circuit that takes AC power (when connected to utility/generator power) andtransforms it into DC power to recharge your batteries.1.2.1 Inverter ApplicationsAn inverter can be used for backup power in a home or office that normally uses utility power.When the utility power is available, the inverter keeps the batteries charged. When the utility powerfails, the inverter comes on automatically to supply AC power to your home or office during thepower failure. For a home or business, reliable back-up power is used to prevent lost computerdata 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 Advantages of a Pure Sine Wave InverterToday’s inverters come in two basic output waveforms: modified sine (which is actually a modifiedsquare wave) and pure sine wave. Modified sine wave inverters approximate a pure sine wave-form and will run most appliances and electronics without any problems. These inverters are lessexpensive and, therefore, offer a viable alternative to more expensive pure sine inverters.The MS-PAE Series provides a pure sine wave output, this waveform is equal to or, in many cases,better than the grid power used in your home. Virtually any electronic device will operate from apure sine wave inverter. Motors run cooler, microwaves usually cook faster and clocks keep bettertime just to name a few examples. Without compromising quality or performance, the MS-PAESeries provides you with all of the advantages of a pure sine wave inverter at a much lower costthan many in the market.1.2.3 Appliances and Run TimeThe MS-PAE Series inverter/charger can power a wide range of household appliances includingsmall motors, hair dryers, clocks and other electrical devices. As with any appliance using batteriesfor power, there is a certain length of time that it can run - this is called “run time.” Actual runtime depends on several variables including the size and the type of appliance, the type of batter-ies installed in your application, as well as the battery’s capacity and age. Other factors such asthe battery’s state of charge and temperature can also affect the length of time your appliancescan run. See the Battery Bank Sizing section in Appendix C, to determine the battery bank sizeneeded for you loads.Appliances such as TVs, VCRs, stereos, computers, coffee pots, incandescent lights and toast-ers can all be successfully powered by your inverter. Larger electrical appliances, however, suchas stoves, water heaters, etc., can quickly drain your batteries and are not recommended to bepowered by the inverter.All electrical appliances are rated by the amount of power they consume. The rating is printedon the product’s nameplate label, usually located on its chassis near the AC power cord. Eventhough it is difficult to calculate exactly how long an inverter will run a particular appliance, thebest advice is trial and error. Your MS-PAE Series inverter has a built-in LBCO (Low Battery CutOut) safeguard that automatically protects your batteries from over discharge.Info: For the MS-PAE Series inverter/charger to perform optimally, a minimum batterybank of 200 AH is recommended for moderate loads (<1000W) and greater than 400AH for heavy loads (≥1000W).Introduction
