d) Prevents crashes in computers, glitches and noise in monitors.
e) Reliably powers the following devices that normally won’t work with modified sine wave
inverters:
• Laser printers, photocopiers, magneto-optical hard drives.
• Some fluorescent lights with electric ballasts.
• Power tools running on AC motor and variable speed control.
• Sewing machines with speed/microprocessor control.
• Charger for rechargeable battery.
Modified sine wave works well for most devices, and is the most common type of inverter on the
market, as well as the most economical.
If you mostly want to run lights (none ballast), TV, kettle, heater, etc, a modified sine wave inverter
is suitable for your needs.
Pure sine wave inverters (also known as true sine wave) are more suited for sensitive electrical
devices such as laser printers, inductive devices (ballast, compressor, AC motor), variable speed
control devices and audio equipment.
Using an Inverter for Emergency Home Backup Power
A very simple way to use an inverter for emergency power (such as during a power outage), is to
use a car battery (with the vehicle running), and an extension cord running into the house, where
you can then plug in electrical appliances.
What output power inverter should I buy?
The output power you require depends on the power (Watts) of devices that you want to run. The
power information of most devices can usually can be found on a specification label on the product
or packaging, if you have any uncertainty please contact the retailer or customer service department
of the manufacturer. We recommend you choose an inverter with 20 to 50% extra of total power
required and with minimum of twice the power of the largest device you will be using.
The reason for requiring twice the largest power device is that the power rating on any device is
based on continuous power. When an electronic device is starting up, there is a surge of current.
This power surge is normally two times, but can be up to seven times (such as ac motors), of the
rated continuous power. Therefore choosing an inverter with a higher power output will reduce the
risk or damaging your electrical items, power supply or the inverter itself.
