why we do it

We’ve been there - Loadshedding Stress

As South Africans, we too have suffered stressful trauma as we saw the devastating affect on our homes and our businesses as the loadshedding phenomena went from bad to worse with no end in sight. 

We found that not only were other commercially available inverters very expensive, they simply did not seem to fit out needs or our budget.

Our systems start at as little as R 5 999

*While stocks last

Don't let load shedding paralyse your life and business any more.

Brilliant Business Opportunity

The failure of Eskom has opened up a business opportunity of a life time. You can become an agent or even own a Franchise selling solar. 

6 simple steps to solving your loadshedding stress


Step 1 – Keep Essentials Connected For Loadshedding

Much of our work, study, internet and day to day communication requires WIFI internet connectivity, and step one is to secure your WIFI, and provide power to your home workstation though rolling blackouts.
The Power in a Box home inverter for R 5999 will give your home office 4 or 5 hours of backup. 

Step 2 – Keep Essentials Connected For Blackouts

By adding 200 W Solar panels to your Power in a Box for around R3000 each, you can use the sun’s energy to power your home office.
In one of those extended 2 or 3 day power blackouts that are becoming all too common, your solar panels will power your office requirement while it charges your batteries to leave you with an additional 4 hours of backup -after the sun goes down!

Step 3 – Keep Home Connected For Loadshedding

The next step would be to connect an inverter into your home grid.
A medium sized home will use about 30 KWh per day, but most of that will be used by your geyser, with approximately 400W – 700W being the average household appliance load apart from the geyser.
By installing a good quality inverter and battery in your house to power your essential appliance load of say, 400W ( excluding your geyser) you can ensure that life goes on pretty much normally during extended hours of loadshedding.
A 5 KW inverter with a 3 to 5KWh lithium battery is a good place to start.
An appliance load of 400W for 10 hours of backup will require 400 X 10 = 4000 Wh or 4Kwh. Lithium batteries allow you to use about 80% of the rated battery, so a 5KWh battery would suffice.
Your geyser would remain on the power grid, and would be warmed up only when the power grid is functioning. Heat will be stored up in your geyser for when you need it, so your geyser would function as a “heat battery”.
Power in a Box supply fully installed Home inverter systems from R68 000 together with an Electrical Compliance Certificate – A COC is essential to make sure the installation is done properly and doesn’t nullify your home insurance policy 

Step 4 – Keep Home Connected For Blackouts With Solar

By adding solar panels to match your installed inverter you can start converting the sun’s energy into useful electricity for your home.
8 X 550 W Solar panels should provide you with approximately 3000 Watts for 6 hours per day in sunny conditions. That equates to about 18 KWh per day, which is more than the requirements to run the essential appliances of a medium sized home. ( eg 500 W appliance load for 24 hours = 12KWh per day )
Cost varies dramatically dependent on your installer and your individual requirements.
Power in a Box offers a home starter solar solution for R 103 000.
A power audit will establish your individual needs. [Click here for a free power audit.] 

Step 5 - Complete Blackout Protection

A normal 150 to 200 L geyser uses 3KW for about 3 hours to heat up your geyser from cold to full temperature of around 65 degrees. IE 9KWh to heat your geyser
A heat pump works on the same principal as an airconditioner. An air conditioner extracts heat from inside and transfers it outside into the atmosphere. A heat pump extracts heat from the air outside and transfers it to your geyser. A heat pump will typically only use 1KW for 3 hours ie 3KWh to heat your geyser.
If your solar system is well balanced with your current appliance load, then you only have to add 3KWh of solar generating capacity to take this step.
A heat pump installed with your existing geyser would cost around R 25 000. 

Step 6 - Completely Off The Power Grid – Solar full house

Completely off the grid is very expensive to achieve as you need to not only provide enough solar for daily consumption and keep your batteries 100% topped up , but you need to have reserve battery capacity to last a cloudy rainy weather.
Depending on your location, you may have to allow for up to 7 days rainy day extra battery capacity or add a diesel/petrol generator to your system.
Power in a Box have an OFF THE GRID product starting at around R250 000 before adding extra “rainy day” battery capacity.

 
Take back the power!
This article is to be seen as a general guide only, a starting point to help you get your head around the requirements, and costs involved of getting off the power grid and taking back control of your life.

 
Every household would require a power audit to establish your power requirements and then a system that can grow incrementally can be designed to suit your power needs.

Rated 5 stars  out of 5, based on all reviews

Power in the box is an amazing product which helped me immensely with school because I could now do homework during load shedding that require my computer to complete and as well as that I didn't have to save work consistently when loadshedding was about to hit for fear of losing my work.

It was such a weight off my shoulders because I didn't have to memorise schedules anymore. It was like loadshedding wasn't there anymore.

House Solar Box

Going solar is inevitable! 

Unstable and ever more expensive Eskom power supply is a specter that faces all South Africans. The power supply crisis in South Africa is not going away and we need to all make urgent plans to secure our own power supply. 

The government has no immediate solution to fix Eskom, but have given individuals and businesses significant financial incentives to secure their own renewal electrical power solutions in the next 2 years. 

Getting your house Off The Grid has never been more important, and short term incentives by the government make urgent action essential.

" Stop paying Eskom for terrible service and start getting your power from the sun!"

Neil Vorster

Renewable power in the form of Solar panels, Inverter and LiFePo Lithium batteries must be professionally installed with a electrical certificate of compliance (COC) to qualify for the government tax incentives and comply with home insurance requirements .

Rated 5 stars  out of 5,  based on all reviews

After multiple hours of power outages when my non-profit organisation could not function, power in a box has completely changed my experience of loadshedding.
Now when the power goes out, the UPS kicks in immediately, keeping the WiFi, my laptop and our lights on and running seamlessly.
Since I got a power in the box, it is finally business as usual no matter what Eskom throws at us!

So glad I bought the Power in a Box.

I work from home and live in a townhouse. Loadshedding is a real problem and I would be lost without my nifty inverter.

When loadshedding hits my area I don't have to worry anymore, I carry on working.

How long does it take to install Solar in my home?

Typically a home solar installation takes a full day, but supply of solar panels, batteries and inverters is the primary cause of delays. 

The recent spate of load shedding has drastically increased demand resulting in supply shortages of up to 4 weeks. 

The process of installing solar or installing an inverter in your home starts with your application [here].

One of technical sales staff will contact you to ascertain your exact requirements and give you an estimated  cost of installation, followed by a site visit and exact quotation of the system that will best suit you .

How long can I expect my PLUG AND PLAY inverter batteries to last?

The Enertec Deep Cycle Heavy duty sealed lead acid batteries that we use are designed to last 600 full cycles or if used carefully buy not completely depleting the battery on each charging cycle you can see  years of daily use

Batteries last MUCH LONGER if handled properly.

If you overuse  your battery by  discharging it too deeply, or drawing a very heavy load continuously,  they will only last a few months, no matter what brand of deep cycle batteries one uses.

Make sure that the inverter or UPS you use has automatic  low voltage cutoff set properly to shut off  before your batteries discharge too deeply. Deep discharge will ruin any lead acid battery very quickly. In my experience battery brand is not the main cause of failure, normally unwitting battery abuse is the culprit!!!

Another battery maintenance tip that nobody speaks about is the continuous amperage that you pull from the battery.

A very experienced battery supplier that I have come to rely heavily on, recommends that your continuous design load does not draw more than 15 - 18 Amps from a 12 V deep cycle battery. This 15- 18 Amp target is guesswork, but experience counts in this industry!

Divide your normal inverter load (in Watts) by the voltage of your battery ( probably 12 or 24 Volts) to obtain the current draw on your batteries.

Example

A 240 Watt load on a 12 V system would draw 240W/12V = 20 Amps – which is a bit too high !!!

On a 24 V system, the same load would only be drawing 240W/24 V = 10 Amps which is very low and consequently you can expect excellent endurance from your battery - again as long as you do not discharge it to deeply!

Is Load shedding affecting your business or studies?

Unfortunately load shedding it is effecting every student, every home and small business equally. The lights go off and everything stops, internet, computer, lights, microwave, stove, kettle, electric gate.

Since Covid, schooling and university/colleges have evolved their methods to rely heavily on the internet for, homework, projects and assessments.

I watch my 15 year old son get back from sport at around 6pm with the pressure of another 2 hours of homework to look forward to, only to have to deal with loadshedding from 6pm to 10pm. And every day the loadshedding schedule changes which adds to the stress.

So what is the solution? A generator, inverter, UPS, solar – or completely off the grid?

Heaven help you if you ask a shop assistants advice- I have found that 99% of the population know very little about Volts, Amps, AC current, DC Current, Watts, VA, Ah, Wh, battery capacityetc.

They know even less about batteries and how to select the best battery for your application.

How do you choose ?

Petrol or diesel generator, inverter, UPS or solar

Lets look at the options in more detail and hopefully bring some clarity into this backup power problem that all South Africans have been thrust into.

The pros and cons of each backup power option for a household:

Petrol Generator

Pros:

  • Provides high power output for long periods of time, making it suitable for large power needs or prolonged power outages
  • Can power larger household appliances and electronics
  • Widely available and can be purchased at hardware stores or online
  • Can be used for outdoor activities like camping

Cons:

  • Requires regular maintenance and fuel refills, which can be costly and time-consuming
  • Produces noise and emits toxic exhaust fumes, which can be unpleasant and harmful to the environment
  • Can be expensive to purchase initially, as well as operate and maintain over time
  • May not be allowed in certain residential areas due to noise
  • Unless you have a covered outside area, rain can stop you in your tracks.


Inverter

Pros:

  • Runs quietly and produces no emissions, making it an environmentally-friendly option
  • Requires little maintenance and is easy to operate
  • Can be powered by renewable energy sources like solar panels
  • Portable and lightweight, making it easy to move and transport
  • Typically less expensive than petrol generators

Cons:

  • Provides limited power output for shorter periods of time, making it less suitable for large power needs or prolonged outages
  • Can only power smaller household appliances and electronics
  • Requires initial investment in batteries or solar panels, which can be costly
  • Unplugging from power source and recharging between usage cycles
  • May not be suitable for areas with long power outages

UPS

Pros:

  • Provides an instant backup power source during short power outages
  • Requires minimal maintenance and is easy to use
  • Produces no noise or emissions, making it an environmentally-friendly option
  • Can be used to protect sensitive electronics from power surges and outages

Cons:

  • Provides limited power output for short periods of time, making it less suitable for large power needs or prolonged outages
  • Can only power small household appliances and electronics
  • May not be suitable for areas with long power outages


In Summary

For a small office or home usage where the load required to run your essential electronics is relatively low, the convenience of a UPS wins every time.

Basic Inverters are bit more inconvenient than a UPS since they generally require you to alternately plug and unplug your equipment into the mains or the inverter.

For farms, or areas where noise is not  a problem and frequent extended power cuts are common, I would recommend a generator.

And since we live in sunny South Africa, I believe the target for every household should be to move to solar (normally in stages) in a totally off the grid solution.

How to take a small office off the power grid in 2 steps?

Loadshedding is playing havoc with all of us. For those working in large offices, you probably have power backup all sorted! But what about the small businessman or woman.

With a small office, cashflow is everything, and for the cash to flow, you need to remain productive.

Small businesses normally operate from home or rented premises making a permanent solar backup system impossible.

Power In A Box was developed for precisely this reason.

How to get off the grid.

Step 1 – Make loadshedding history – buy a Power In a Box unit.

The basic Power In A  box unit plugs into mains power and charges the batteries while the power is on. Then when the lights dip, you don’t.

In this video, I unbox our entry level unit (Power in a Box – Small office and Home) so that you can see all the components and how simple it is to install.


To avoid your battery running dry before the power comes back on, and to ensure that the battery lives up to its design life, it is vitally important that you select the correct model.

  • Total up the power requirements of all your absolutely essential equipment such as PC, Laptops, celllpone charger, desk lamp. If you don’t have a power meter ( Who has ?  ), check the each item to see its power input requirements – normally stamped underneath each item.  
  • In our example used in this short video, we totaled 96W for 1 desktop PC, 1 screen, 1 PC, 1 lamp, cellphone charger, WIFI and an emergency lamp.
  • The entry level Power In A Box comes with a 12 Volt, 80Ahr heavy duty, deep discharge, sealed lead acid battery. In your capacity calculations, always plan on using only 50% of the total capacity to ensure that your  battery does not expire early. I liken using all of your capacity to over revving your car between every gear. That car wont last very long. Experience has taught us to use only 50% capacity.
  • To work our how many hours your small office will safely run while Eskom has put you in the dark, you will need to remember some school electricity… or just follow these steps.

Usage = 96W, battery 12V 80Ahr

Amps draw on your battery = 96W/12V = 8 Amps.

Half capacity of the battery is 40 Ahr.

40 Ahr/8 A = 5 hours

This means that with a constant load of 100W, you can safely run for 5 hours.

In this short video, Eskom obliged me by providing a blackout as precisely the correct time to demonstrate the uninterrupted power the Power in a box supplied

 

Step 2  Beat the blackouts – get your office off the grid.

Our aging electrical infrastructure was not designed to switched on and off 8 times a day. As a result we frequently experience localized blackouts for 2 or three days at the time and sometimes even longer. The answer is to connect your Power In a Box unit to solar power.

This is far easier than you might think. The Power In A Box unit comes solar ready, simply plug an play as shown in the video below.

Using the above example of 96 Watts to run your office essentials, we recommend a solar panel of between 100 and 350 W. The bigger your panel, the quicker your battery will charge up. But since you are only using 96 Watts, a very good bang for your Buck is a 200W solar panel .

  Unboxing the Solar panel.  


In the video, it is clear that on a normal sunny day, your small office can run completely off the grid. During sunny hours the solar panel will supply all your power requirements with more than enough left over to charge up your batteries. When the sun sets your battery takes over, giving you an additional 5 hours.

This 5 hours is easily extended to 10 hours by installing another battery in parallel to the first one, giving you 80 usable Amp hours.

On a cloudy day, you will have the option of connecting to the grid and relying on Eskom to charge your batteries between Loadshedding events.

How is Loadshedding effecting South Africans?

Load shedding is having a significant and adverse impact on South Africans in many ways.

  1. Load shedding disrupts daily life, causing inconvenience and frustration. Scheduled power outages mean that work is disrupted, you are unable to cook meals, use appliances, do your homework, access the internet.
  2. Small businesses: Load shedding has a significant impact on businesses, with power outages causing disruption to everyday work activities. When the power dips, so does your productivity and you lose income.
  3. Security:  Load shedding can result in increased crime as security systems, alarms and streetlights are disrupted.
  4. Health concerns: Load shedding can affect life-saving medical equipment like respirators for the sick frail and aged.
  5. Loss of perishable goods: How much food have you lost due to loadshedding ?
  6. Emotional stress: Load shedding causes emotional stress, with people feeling anxious and uncertain about when power will be restored, how to meet deadline, how to finish your homework causing a sense of powerlessness and helplessness.
  7. It is essential to address the Loadshedding problem as it is here for the foreseeable future, I am afraid.

The Solution

So what are the options for a household or a small business ?  What if you work from home, since so many South Africans are working from home or running a small business from home.

The obvious solution is to install a substantial solar power system and get off the grid completely, get control back and stop being subject to the dreadful inefficiencies and inconvenience of Loadshedding. But unfortunately for most South Africans, this costs a small fortune upwards of R400 000.

A phased approach 

Step 1

Load-shed proof your home office, your students, your entertainment like TV and internet.

Get a Power In A Box – Home and Student  UPS. Its a great cost effective solution, which stays plugged into the grid while supplying you power that is uninterrupted when loadshedding kicks in.

This short video demonstrates the capabilities of Power In A Box, and as providence would have it, I was loadshed while filming which provided a great live demonstration of the system.  


Step 2

Purchase a single solar panel sized between 200 and 350 Watts and plug  it directly into your Power in A Box. 5 or 6 hours in full sun is enough to keep your battery charged and supply you with electricity all day. This will take your basic home office/entertainment/student essentials completely off the Grid.
