What does the inverter do?
The inverter converts the battery DC voltage (usually 12, 24 or 48 volt)
to 240 volt AC to allow the use of normal AC power appliances.
What is the continuous rating?
Every inverter has a rating for continuous and surge usage.
rating is the wattage of appliance that the inverter can run continuously
for hours at a time (provided there is power available from the battery
What is the surge rating?
The surge rating shows the inverter's ability to operate short-term
loads for the starting of heavy appliances such as motors.
As an example,
a 700 watt inverter with 2000 watt surge capacity would be able to operate
a 400 watt washing machine that requires 1200 watts to start its spin
What is the ability to operate appliances?
Some manufacturers also publish 30 minute ratings for their inverters
which indicates their ability to operate appliances with a higher wattage
for short periods (e.g. a 1200 watt inverter operating a 1400 watt vacuum
Previously only modified square wave inverter models were available. Modified
square wave inverters will run most appliances successfully, especially
if they are not electronically or multi-speed controlled.
Because of their
imperfect wave form, these inverters will cause some interference on AM
radio and may cause background hum in stereo equipment, minor interference
with TV and video recorder pictures and problems with variable speed appliances,
such as fans.
What are the most common inverters?
Most inverters on the market today are sine wave inverters
(that is, they have a wave form similar to the power from the electricity
grid, if not better).
What are the advantages of sine wave inverters?
Sine wave inverters have the advantages of fewer
equipment compatibility problems and lower distortion, noise and radio
Some companies have ceased to manufacture modified
square wave inverters in favour of a better variety of sine wave models.
