Why you need an Inverter

An Inverter is an essential appliance in countries that experience frequent power cuts; it converts PV-generated or battery-stored DC power into AC electricity that can be used to power home and office appliances.

NEPA or no NEPA,  you don,t have to be stranded in the dark with no electricity to keep smartphones, tablets, and other devices powered up and productive.

Modified vs Pure Shine Wave

There are two main types of inverters available on the market.  Modified Sine Wave and Pure Sine Wave.  If you wish to power small household appliances like lights, TV,s, and fans. Modified Sine Wave inverters are affordable and have high efficiency. They will provide you with power comparable (but not identical) to what you get from NEPA.

If you would like to run larger appliances like a fridge, freezer, AC, or medical equipment you should go for Pure Sine Wave.  They are ideal for motor startups,  make little or no noise and give power quality equivalent to what you get from NEPA, however, Pure Sine Wave can cost twice as much as an equivalent Modified Sine Wave unit.

Inverter Size

To choose the right size for your needs, calculate the total wattage of all the electrical appliances you would like to run when NEPA is unavailable.  This can be achieved by checking the power rating label found on each appliance and adding up the total wattage.  If you wish to keep your total cost down,  it is advisable to run only your essential when there is no NEPA.  The following is an example:

Equipment	Common Energy Consumption in Watts
Laptop	20W
Ceiling Fan	50W
DSTV	20W
Televisions	150W
Desktop Computer	85W
4 Energy Saving Bulbs	60W
TOTAL	385W

We recommend that you buy an inverter twice the size of your total energy requirements so that you have extra capacity and do not run the risk of overloading.
