HOW YOUR VECTOR INVERTER WORKS The inverter converts low voltage DC (direct current) from a battery or other power source to standard 110 volt AC (alternating current) household power. 3.1 PRINCIPLE OF OPERATION The inverter converts power in two stages.
The modified sine wave produced by the MAXX 750 SST inverter has an RMS (root mean square) voltage of 110 volts, which is the same as standard household power. Most AC voltmeters (both digital and analog) are sensitive to the average value of the waveform rather than the RMS value. They are calibrated for RMS voltage under the assumption that the waveform measured will be a pure sine wave. These meters will not read the RMS voltage of a modified sine wave correctly.
CAUTION: Reverse polarity connection will result in a blown fuse and may cause permanent damage to the inverter. CONNECTING TO A POWER SOURCE USING PROVIDED CABLES: Use the provided cables to connect the MAXX 750 SST directly to the 12 volt power source using the following guidelines: 1. Check to be sure the MAXX 750 SST power switch is turned off and that no flammable fumes are present. 2. Connect the black cable to the black post marked “(-)” on the back of the inverter.
4.3 CONNECTION TO LOAD The MAXX 750 SST is equipped with dual standard North American AC power receptacles. Plug the cord from the equipment you wish to operate into the AC receptacle(s). The green LED indicator lights to indicate that the inverter is functioning. Make sure the combined load requirement of your equipment does not exceed 750 watts. The MAXX 750 SST is engineered to be connected directly to standard electrical and electronic equipment in the manner described above.
5. OPERATING TIPS 5.1 RATED VERSUS ACTUAL CURRENT DRAW OF EQUIPMENT Most electrical tools, appliances and audio/video equipment have labels that indicate the power consumption in amps or watts. Be sure that the power consumption of the item you wish to operate is rated at 750 watts or less (If the power consumption is rated in amps AC, simply multiply by the AC volts (110) to determine the wattage). The inverter has overload protection, so it is safe to try to operate equipment rated at 750 watts or less.
OVER VOLTAGE PROTECTION - The MAXX 750 SST will automatically shut down when the input voltage exceeds 15.5 volts DC. SHORT CIRCUIT PROTECTION - Reverse polarity or a short circuit condition will usually result in an external or internal fuse being blown. OVERLOAD PROTECTION - The inverter will automatically shut down when the continuous draw exceeds 750 watts. When the overload is removed the inverter will self-start.
