Inverter Battery Load Shedding Kits

Inverter Battery Load Shedding Kits

If you're looking for a reliable load shedding solution to end the always-present grid failure struggle, an inverter battery system is the one for you.

The grid failure crisis has wreaked havoc on our economy over the last ten years, and many South Africans agree that there is a way to lessen the burden: Buy an Inverter Battery system.

Deciding to buy a battery and inverter for load shedding has dramatically improved the quality of life for many families in South Africa because they no longer have the weight of having to prepare for grid failure. Installing a battery backup kit allows for future growth of these homes by being converted to a Solar Power Kit so they can produce their own power instead of relying on the grid.

Energy independence is a necessity today, and we hope to see many more homes and businesses achieve this because who knows what the future holds for us. Instead, plan for the worst and hope for the best.

How do Inverter Battery Kits Work?

Alternative current (AC) power from the grid is pulled by a solar inverter where it is converted to Direct current (DC) power and fed into the battery bank and stored as emergency backup power.

When load shedding strikes, the solar inverter will pull the stored backup power, convert the DC power back into AC power which can then be used in our homes.

The products in our plug-and-play systems make them the perfect battery and inverter for home and business use to combat load shedding.




How to Size an Inverter Battery Kit

Choosing an inverter battery backup system may seem daunting initially, but we have some tools and guides available to help you make informed decisions. If all else fails, our sales team are here to help you.

Our backup power kits consist of only the best quality products that have stood the test of time and proven efficient, safe and reliable. They are the perfect load shedding solution for any home or business.

Our products have excellent manufacturer warranties, and we offer a complimentary RMA service to all our clients.

An added bonus of these battery backup kits for load shedding is that you can add a solar array at a later stage to produce your own free electricity. And in doing so, it gives you energy independence from high electricity bills and Eskom’s load shedding.

Choosing an Inverter

Inverter Type:

This is the most important decision to make, and the inverter type is usually determined by what your end goal is.

We highly recommend a Hybrid inverter if you want to add a solar array at some point down the road. If you’re only interested in a load shedding solution, then an off-grid inverter kit will work perfectly.

We only offer the best quality inverters for sale because we know that these products work, and we want you to buy the best solar equipment available. This will prevent disappointment and system issues in the long run.

Hybrid Inverters

Hybrids can blend power from all available power sources, which means that your home will never be without power.

Another beneficial feature is that the hybrid inverter will use the available battery backup and pull the excess from the grid. Ensuring you are constantly using available free power and only supplementing the deficit with grid supply.

Most hybrid inverters have a UPS (uninterrupted power supply) feature, so you don't have any downtime when power source switching happens.

Off-Grid Inverters

Contrary to Hybrids, Off-grid inverters cannot blend all available power sources. Some do not blend at all, and others can blend solar and grid supply. The latter could benefit a home that uses all of its power during the day and minimal power at night.

You'll need to ensure your usage does not exceed your battery's discharge capacity because it will just switch to grid usage, and you will be paying for electricity. Even though you have freely produced solar power sitting in your unused battery backup.

These are inverter battery load shedding solutions because blending is not needed, and their price point is lower than the Hybrids.

Inverter Size

If you plan on adding a solar panel array later, I suggest looking at our Solar Inverter Battery Kits. A calculator on each page will take your average monthly electricity bill amount and determine how many kWh you use per month. From there, the calculator can determine what size kit best suits your needs. You'd then be able to pick a load shedding option based on your findings.

For the average household, a 5kW inverter is more than enough for a load shedding kit. So long as your usage at any given time does not exceed the inverter's rating because this will trip the system.

To start, work out which appliances you need to run during grid failure and add up all their ratings. If your total is on the high end of 4kW, an 8kW or two 5kW inverters will need to be used instead. Alternatively, see if there are some appliances that you can remove from your essentials list.

Choosing a Battery

Lithium-ion is King

Finding a battery for home use has become necessary for all South Africans to protect their homes from power failures. And it's easier than you think to size up a battery bank.

Lithium-ion solar batteries are the most reliable, scalable and safest deep cycle batteries on the market today.

Before we start, it's important to note that being mindful of what you are running during load shedding will help your backup to last longer.

Gathering Your Data

This is the information you'll need to start working out your needs:

  • What appliances do you want to run
  • The appliances rating in watts
  • The duration you'll be using those appliances for


To work out each appliance's total usage, take the rating in watts and times that by the number of hours you'll need to run them.

For LED lights, TVs, Wifi router, DSTV decoders, fridges etc., it's straightforward because these things are on all the time during grid failure, which is around 2.5 - 4.5 hours.

But for appliances that are only on for a matter of minutes, you'll work out their usage like this:
Watts / 60 (minutes in an hour) * number of minutes in use.

Find Your Total

Once you have all your totals, add them up, which will be the battery bank size you'll need. It would be best to choose a slightly larger battery bank than your total needs.

Please consider the DOD of the Lithium battery you choose.
