Inverters are a great way to have a power back up for yourself in the summer months.
I have tried the Power Bright ML1500-24 1500 Watt 24 Volt DC To 110 Volt AC Power Inverter. You could buy inverters from Amazon.com. There are so many brands for your choice.
It has worked well for me and all the appliances I have connected to it so far.
But before you buy an inverter, from any brand whatsoever, make sure you do the following at any cost:
1. Make a list of all the electrical appliances and devices you need to have backed-up at all points of time.
It is always wisdom to make the list keeping in mind that an inverter unlike a generator cannot be used to run air conditioners
Modified Sine Wave works well for most uses, and is the most common type of inverter on the market, as well as the most economical, Pure Sine Wave inveters(also called True Sine Wave ) are more suited for sensitive electrical or electronic items such as laptop computers, stereos, laser printers, certain specialized applications such as medical equipment, a pellet stove with an internal computer, digital clocks, bread makers with mulit-stage timers, and variable speed or rechargeable tools (see “Appliance Cautions “). If you wish to use those items with an inverter,then choose a Pure Sine wave inverter. If you mostly wnat to run lights, TV, microwave oven, tools, etc, a Modified Sine Wave inverter is fine for your needs.
About the question : Whether computers will work with Modified Sine Wave.
From the point of professional: Most (with the exception of some laptops) will work (though some monitors will have interference such as lines or a hum), However, if you have any doubt about any appliance, tool or device, particularly laptop computers and medical equipment such as oxygen concentrators, we recommend that you check with its manufacturer to be sure it is compatible with a Modified Sine Wave inverter. If it is not, choose one of our Pure Sine Inverters instead.
The difference between them is the Pure Sine Wave inverter produces a better and cleaner current. They are also considerably more expensive. You might find it practical to get a small Pure Sine Wave inverter for any “special need” you may have, and also a larger Modified Sine Wave inverter for the rest of your applications.
