Frequently Asked Question
What Kind of Inverter do I need?
What kind of inverter do I need? The type and size of inverter
necessary depends on your application. To determine this you must first
calculate the maximum amount of load you will be running on the inverter
at one time.
There are basically four size ranges of inverters. The first
is 50-300 watts; these are small portable inverters. These inverters are
ideal for laptops, small lights and other minimal draw AC loads.
The next size range is 300-800 watts. These are also somewhat
portable and still have the outlets on the front of the inverter. This size
inverter is good for small microwaves and other small appliances.
The third range is from 800-2000 watts. These units usually
have battery chargers built into them. Your can recharge your batteries
with utility power or generator power. They are also great for powering medium
size AC loads, or running multiple smaller loads at one time. These units
are typically permanently installed.
The final inverter grouping is a permanently installed units
ranging 2,000-11,000 watts. They function much like small generators, yet
are completely silent in operation. They are great for your larger loads,
such as refrigerators.
The other question that needs to be answered when selecting
an inverter is the type of wave form. If you are running sensitive electronic
equipment, like fax machines, laser printers or high tech stereo equipment
you need a sine wave inverter. A sine wave inverter has a wave form that
is very similar to the form of grid electricity. Other options may include
modified sine wave, which is fine for items that are not supersensitive
to clean power. You may experience a humming sound when powering clocks, and
small radios on a modified sine wave inverter
