Choosing an Inverter

modified vs sine inverterWhen choosing an Inverter you need to consider how much wattage you’re going to be drawing and what the most wattage you’ll need to draw at any instant might be. You’ll also have to think about how sensitive the electronics are that you’ll be using with your inverter. Choosing an Inverter is then pretty easy, with these considerations in mind you’ll know:

  1. What wattage rating you need
  2. Whether or not you’ll need a modified or pure sine wave inverter

If you’re just looking to keep a couple of refrigerators or freezers running you may only need a 1500 watt modified sine wave inverter that you can get for under $100. If you’re wanting to run all the electronics and lights in your small town home, you might be needing a 3,000 watt pure sine wave inverter.

How do I know how many Watts I’ll need?

Before choosing an inverter,the best way to find out how many watts your inverter will need to handle is to use a Kill-A-Watt Meter. It’s a meter that does all the math for you. All you have to do is plug it into your wall and then plug the appliance or electronic into the meter. It will meter with in .02% accuracy the same readings that your electric company looks at each month- how much energy is used in Kilo Watt Hours (kWH). 1 kilo watt hour is the energy used to run a 1,000 watt device for one hour- a space heater for example. This info will also help you for choosing a battery.

What type of Sine Wave Inverter do I need?

If you are going to be running sensitive electronics you’ll want to used a pure sine wave inverter. The current from these meters can be even purer or cleaner than the power you get from your energy company. You’ll especially want this type if you’re going to run efficient Hg light bulbs computers, or HDTV’s.
