How to choose the right type of inverter for your home or business?

The promise of uninterrupted electricity today isn’t a grantee for most developing or 3rd world countries. In fact, most countries produce drastically less power than their average population demands just because some lack the expertise or resources to do so. So, as a backup measure, most business and households resort to some form of backup power to fill in the gaps when there is a power cut. However, given the vast amount of choices inverter brands and models that are currently present in that market today, you may quickly find it confusing or to zero-in a particular model which might adequately fulfil your wattage requirements.

1. Sine Wave Inverters

2. Square Wave Inverters

There are other types of inverters available as well, but these are the most popular inverter types that are commercially sold in the markets.

Choosing a Inverter setup that’s right for your home.

Now as you know, the core components needed for the setup is that battery and the Inverter unit itself. You can either buy battery online or grab one from you nearest authorised distributor. However before you decide to go for battery online shopping, do make sure to consult your electrical engineer so that you get the adequate capacity.

Now there are a few things that you need to check before making the purchase:

1. Does your establishment have heavy machinery or appliance that requires constant, high flow of electricity?

2. Do you plan on using the unit to power specific equipment that requires simulated power draw or that draws power linearly?.

3. The size of your establishment.

4. Total amount of equipment requiring backup power.

5. Mission critical equipment..

With that said, let me explain why you need to keep those in consideration.

Basically, Sine wave inverters and Square wave inverters work in two different principles.

While Sine Wave Inverters convert the DC energy stored in the battery into AC before outputting, square wave inverters transmit them as DC. So, while sine wave inverters will transmit stable electricity over longer distances, square wave inverters might need additional relay points in case of using it for longer distances. Hence the size of the establishment is an important consideration.

Secondly, Appliances requiring high amounts of energy output might benefit from a square wave inverter as DC current usually gets passed on in higher amounts than AC. So, the type of equipment needing backup power is also another important consideration.

Thirdly, Square Wave Inverters are a very cost effective option if your premises requires power backup on multiple low voltage circuits. Plus, you can get away with an offline power backup system should that be the case. However, it is usually a better idea to get an online UPS for backup power if the equipment in question is mission critical or needs uninterrupted power all the time.


Most average households will usually be fine with a modest sine wave inverter system since that is more efficient and requires less maintenance. However, if the energy requirements for your premises are large, you should consult an electrician and calculate the amount of power that you need. The inverter company will often have experts regarding this, and you should definitely consult them once so that your power requirements are met well.
