Forget the technical mumbo-jumbo

we simplify & eliminate the aggravation

What are inverters

Overcoming the LoadShed-ed crisis presents two objectives: 1) Insulate sensitive electronics (DSTV, computers, fridges) from repeated catastrophic crashes when Eskom fails, 2) Have electricity (light, TV, Wi-Fi) during an outage.

 

To do this you must 1) Make new energy (generator / solar) or, 2) store Eskom energy....​

Whichever you choose - storing and 'smoothing' the energy flow through an inverter is critical.  Why?  Because batteries store 12-volt and everything uses 220v - and the 220 produced by generators fluctuates too much to connect sensitive equipment to it.

i.e. - If you connect your DSTV/Wi-Fi/Computer/Cash Till directly to a generator (and it's already crashed), the fluctuating power supply might well damage or catastrophically destroy those components anyway.

 

So - an inverter/battery combo is an unavoidable first piece of equpment you need no matter what other solution you seek - it's the platform you need to add solar and generator.

What is an inverter?  it's a 'converter' - it turns 220v (from Eskom) into 12v for a battery to store, and it re-converts 12v back into 220v for your sensitive equipment to use.

 

How does it connect?

Couldn't be simpler.  The size of 2-shoe boxes, you simply plug its input lead/plug into Eskom, connect it to a car-style (deep cycle) battery, and plug a multi-plug into its output and then permanently connect all sensitive equipment to it.

The effect is that your equipment is permanently running off of the battery - and the battery is permanently being topped up by Eskom (or solar).  When the power fails (Eskom quits, wind drops, sun goes down) your equipment "doesn't even realize" because it keeps running on the battery - the battery is simply not being topped up till the power supply returns.

Voila!

It's an attractive component - but when you mount it inside a wheeled cabinet - that we can supply - you won't see it anyway.  See: LCD showing status.

What will it look like?

Optional.... Enclosure

As you see - the unit is so attractive, that there's no real reason to hide it.  Generally, the battery(s) are easy to hide behind flat screen TVs or in the existing TV cabinet.

However - if you want an enclosure, we have two options to choose from, both on carstor wheels:

1) A black steel cabinet - battry(s) inside - inverter on top.

2) White or black super-wood - battery(s) inside and inverter behind glass* pane.

 

*Our preimium brand Home and Office units have been tested in a room with ambient 44 decibel sound at 62 decibels 1m from decimeter.  Ellies and Mecer brands both scored over 70 decibels.  Behind the glass, our unit drops to 52 decibels.  With noise cancellation foam, sound drops to 48 decibels.

 
Pure vs Modified Sinewave?

In application, "Sinewave" is a measure of the 'quality' of power - and its compatibility with sensitive electronics.

If you ask around, you'll hear a mention of "pure sinewave" vs "modified sinewave" inverters.

 

If you want to torture your mind with learning about what 'Sinewave' means - link to the Technical Stuff page

 

Let's just clear this up in simple terms:

Electricity has a wave form - pure sinewave is a smooth, undulating wave; at the other end of the scale is 'square wave'.

To grasp the significance, let's draw a real-life analogy:

A component - say, a computer - plugged into an inverter is receiving a never ending stream of waves passing through it; it's a little like driving down a road that rises and falls: Both you and your car's suspension will appreciate if the road-maker took the time to smooth out the undulations so that the undulations have a smoothe rise to each crest.  You would absolutely not enjoy driving if the road is a never-ending seires of squeared-off pavements - crashing endlessly into vertical rises.  That is what a square-wave inverter does - square wave is a disaster for electronic equipment.

Alas - square wave likes to call itself "modified sinewave" - and this

gives modified sinewave a bad name.

 

However - a good quality modified sinewave smoothes out the big

steps in its ossilating waves so that they are as close as possible to

the pure sinewave's 'clean power' required by electronics.

This is why a CE (European) mark of quality assuredness is so critical

to ensure that you are buying a quality product that will be gentle

on your equipment.

 

We can offer you both pure sinewave and top quality modified sinewave (in our DIY range).  It just comes down to your budget.

For TVs, computers, wifi, etc - our modified sinewave units are absolutely adequate - there is no need to spend significantly more money for no gain.

But - if you're going to hook up to your distribution board with a big unit - yes - pure sinewave is the way to go.

 

Keeping it Simple

During a load shed, you have two primary needs, needs that we will meet at an affordable price and without agravation - keeping electronics from (catastrophically) crashing, and keeping some lights.

To do this, we specialize and carry a Home and an Office solution:

"How it Works" video

As a movie director, I can't afford even one hour of power outage - certainly cannot risk my computers crashing before I start a generator.  My Inverter saves my sanity on a daily basis

Gordon Clark, Hout Bay

Last week the Blitz-Boks were heading for the Final - and my DSTV crashed - no PVR recording and the PVR is trashed - blown - throwaway.  I wish I'd put this power management system in before it cost me a lot of money.
