Buying a 220 volt Power Inverter - What You Need to Know to Get the Right Inverter

Inverters are no more part of the luxury list, they have moved into the list of necessities. With work and personal like depending a lot on the availability of power, it makes sense to go in for a power inverter. Choosing one may sometimes not appear as easy as the decision to go in for one. However, with the right selection criteria you can zero in on one in the shortest possible time. Here is how you can home in on the right 220 volt inverter.

Wattage considerations
You do not have to be a geek to figure out the requirements. Take into consideration the number of appliances that you want to be powered by the inverter. Each appliance would have a rated amperage. Add the amperage of all the desired appliance and multiply the total into 120. This will give you a number. And the ideal wattage of the inverter that you need to install in your residence should be more than the number.  This is the simplest way of calculating the wattage.

Signal output – sinusoidal waves
This could appear a little technical for those who may not be technically sound. However, it is a very simple requirement. The signal output of inverters may either be sinusoidal, or square. Insist on a sinusoidal waveform, which may actually be slightly more expensive than a square waveform model. However, the benefits of a sine wave model far outstrip the difference in pricing. The results can be seen in more efficiency, and lesser consumption of power. Ideally sine wave inverters are more reliable and suitable for sensitive equipment.

Battery capacity

The soul of the invertor, the battery capacity determines the efficacy of the inverter. Look for the Ah value in an inverter. Ah in other words is Ampere Hours and this will tell you how long the battery is expected to last, considering the wattage requirement. The total wattage requirement needs to be multiplied by the number of hours you may need the inverter to support you with power and this value needs to be divided by the voltage of the battery. The figure that you see at the end of the calculation should be the minimum Ah of the inverter.

220 Volt Microwave – Great Idea to Save Energy Consumption

Energy efficiency is a key factor in choosing appliances for the home as it brings a lot of long term savings and benefits. An oven for the kitchen is a necessary tool for food preparation. Conventional ovens are now being replaced by the microwave oven as an alternative and efficient tool for cooking and preparing meals for the family. Contrary to popular belief, the microwave oven actually has more practical energy saving value than an electric or traditional gas fired oven. According to Energy Star, the body that oversees and enforces energy performance standards for electrical appliances and devices, a microwave oven actually uses up 30% up to 80% less energy than conventional ovens or electric toasters. This is a huge difference and can definitely impact energy use and operating costs for your home. Conventional ovens often require a preheat cycle; the oven has to be brought up to certain temperature before putting the food in. It therefore uses up more energy. With microwav...
