A power inverter, or inverter, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC).
The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.
A Best Dual Fuel Inverter Generator can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. Static inverters do not use moving parts in the conversion process.
Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and voltages, are called oscillators. Circuits that perform the opposite function, converting AC to DC, are called rectifiers.
To understand the portable inverter generator and how it compares to the common portable generator, we’ll first look at inverter technology in its simplest form.
You might be familiar with a common 12 volt battery inverter which is an electrical device that converts 12-volt DC power into 120-volt AC power.
Typically you run this type of inverter off of your car’s battery or off of a deep-cycle battery that you buy specifically to power the inverter. Although fairly inexpensive, the shortcoming is that typically an inverter is a useful solution if you can keep your power demands in the 200-watt range.
You could get one with a more useful 2,500 watts, but it will cost close to $1000 and that’s not including the bank of deep-cycle batteries and a charging system. For more demand than that, you should consider a fuel powered inverter generator. Unless the “clean” AC power that an inverter provides is important to you.
Consider a car’s battery has a reserve capacity rating. A typical rating is 80 minutes, which means the battery can supply 25 amps at 12 volts for 80 minutes. Without going into the math, if you draw 120 watts continuously, at 10amps, this might last three hours, possibly eight hours on a deep-cycle marine type battery. But then you have to recharge the battery.
The reason I mention that is, some will opt for a portable generator for most of the daytime duties of a power outage, then run a couple of lights at night off of an inverter. You can run a couple of 15 watt bulbs (2.5 amps) for about 12 hours on a car battery.
In addition, your car’s alternator can generally only supply 700 watts. So to run more than a 300watt inverter from a car, you’ll need to connect it directly to the car’s battery with cables, and then you will need to run the car’s engine continuously. So that’s where a gas powered portable generator makes sense.
So why not use the inverter to power anything it can? Then when the batteries are depleted, or you need large loads to turn on, run a standard generator for a long time (at least an hour) to power the heavier loads. Meanwhile let the battery charger then re-charge the battery to give the inverter its efficient power once you’re ready to shut the generator down. This one-two punch allows the most efficient use of fuel (only using a pollutant when you’re getting the most effectiveness out of your fuel). You’ll run the noisier generator less, and equally important, you’ll save money since you’ll use less fuel for the same used kilowatt hours.
Best Dual Fuel Inverter Generator may take some math and some planning, but you can partner a good inverter with a small generator and reap the benefits of a light-weight, highly efficient, usable system.
