Inverters - general information why an inverter is needed the utility grid supplies you with alternating current (ac) electricity. Ac is the standard form of electricity for anything that “plugs in” to the utility power. Direct current (dc) electricity flows in a single direction. Batteries provide ...

Page 5 loads that require “surge power” to start resistive types of loads (like incandescent lamps, toaster, coffee maker, electric range, iron etc) do not require extra power to start. Their starting power is the same as their running power. Some loads like induction motors and high inertia motor d...

Page 6 power rating of microwaves the power rating of the microwave generally refers to the cooking power. The electrical power consumed by the microwave will be approximately 2 times the cooking power. The “surge power” of the inverter should be 2 times the electrical power (i.E., 4 times the cooki...

Page 7 characteristics of sinusoidal ac power voltage, current, power factor, types of loads the voltage waveform of 120 vac, 60 hz mains / utility power is like a sine wave. In a voltage with a sine wave-form, the instantaneous value and polarity of the voltage varies with respect to time and the w...

Page 8 advantages of a pure sine-wave inverter over a modified sine-wave inverter the output voltage of a sine-wave inverter has a sine wave-form like the sine wave-form of the mains / utility voltage. In a sine wave, the voltage rises and falls smoothly with a smoothly changing phase angle and also...

Please note that the ac output connections and the dc input connections on this inverter are not connected (bonded) to the metal chassis of the inverter. Both the input and output connections are isolated from the metal chassis and from each other....

Page 10 grounded electrical power distribution system the national electrical code (nec) requires the use of a “grounded electrical distribu- tion system”. As per this system, one of the two current-carrying conductors is required to be grounded. This grounded conductor is called the “neutral / cold...

Page 11 grounding to earth or to other designated ground for safety, the metal chassis of the inverter is required to be grounded to the earth ground or to the other designated ground (for example, in a mobile rv, the metal frame of the rv is normally designated as the negative dc ground). An equipm...

Page 17 sizing the inverter battery bank one of the most frequently asked question is, “how long will the batteries last?’. This question cannot be answered without knowing the size of the battery system and the load on the inverter. Usually this question is turned around to ask “how long do you wan...
