The Tesla Powerwall home battery will be available worldwide – including in South Africa – by the end of 2016, a spokesperson for the company told MyBroadband.

This follows the recent unveiling of the new battery system from Tesla CEO and South African-born technology entrepreneur Elon Musk, who also revealed at the time that customers in North America and Europe could already pre-order the product.

Powerwall is available as a 7kWh unit for $3,000, and a 10kWh unit for $3,500 – excluding inverters and installation – and will deliver to pre-order customers by “late summer” (July – September 2015).

Tesla explained its approach to the roll-out of the new product to countries like South Africa in the statement below.

“Right now, the Powerwall is available through solar installers, utilities, and energy companies, who can offer Powerwall with installation, which allows for rapid deployment around the world. We work closely with partners to make sure they are qualified and able to install and service the technology.”

Powerwall an innovation in manufacturing, not technology

Head of operations at BrightBlack Stephen Gous said that lithium-ion battery packs similar to the ones Tesla uses in Powerwall are available in South Africa, but are not cost-competitive at the moment.

“The technology itself is not revolutionary, and is based on the Sanyo 18650 Li-ion cell,” said Gous.

What might be considered revolutionary, said Gous, is the manufacturing capacity for the cell has never been as large as it is now thanks to Panasonic’s relationship with the Tesla Gigafactory.

Panasonic has owned Sanyo since 2009.

“That’s why nothing moved ahead with the Gigafactory until Panasonic was completely on board.”

Sanyo owns the patent to the 18650 cell, said Gous, and all current lithium-ion packs are composed of this cell.

“What is open to development is the charging and discharge control of the cell.”

With the ramping up in production due to the Gigafactory, Gous said we will hopefully see more options become available in South Africa at better prices.

He warned that batteries imported from overseas will be hit with the new 30% duty recently imposed by SARS, though.

Coming to South Africa “faster than many would think”


Soltra Energy boss Jack Ward agreed with Gous, but added that he believed the Tesla Powerwall is revolutionary concept.

“Not because the battery system is based on lithium-ion (Li-ion) technology, but because Tesla will bring it to the mass market fully packaged at a very competitive price point so it will no longer be an exotic option,” Ward said.

Asked whether the technology will come to South Africa, Ward said that it most certainly would. “Faster than many would think,” he added.

“Available at a competitive price point, the Tesla system is ideally suited to meeting the power provisioning challenges faced by South African businesses and individuals on a regular basis – load-shedding and power-outages caused by any number of factors, including cable theft,” said Ward.

South Africans also have to deal with regular hikes in the price of electricity and will soon face the introduction of time-of-day billing, or “smart-metering”, which will further increase costs.

“These inevitabilities will underpin the broad acceptance of the Tesla battery — and solar photovoltaics — as a cost-effective, efficient and professionally-supported alternative,” Ward argued.

The Tesla Powerwall home battery is going to be available in South Africa and will be offered with the StorEdge inverter system from SolarEdge.

That’s the word from Lior Handelsman, founder and head of marketing and product strategy at SolarEdge. He said they will introduce StorEdge to the South African market later in 2015.

“This solution is capable of offering both energy backup and daily energy management for maximum self-consumption and electricity bill reduction,” said Handelsman.

He added that the StorEdge system is designed for optimal integration with the Tesla Powerwall battery, and will be provided with it.

News that the Powerwall is coming to South Africa follows Tesla’s confirmation that its new home battery will roll out worldwide by the end of 2016.

“Right now, the Powerwall is available through solar installers, utilities, and energy companies, who can offer Powerwall with installation, which allows for rapid deployment around the world,” a Tesla spokesperson told MyBroadband.

“We work closely with partners to make sure they are qualified and able to install and service the technology.”

While Tesla’s confirmation did bode well for the country, no local partners for the new home battery system were announced.

Soltra Energy CEO Jack Ward said at the time he believes that not only will the Tesla Powerwall come to South Africa, it will be here “faster than many would think.”

Handelsman said release dates and pricing for the Powerwall battery and StorEdge inverter systems have not yet been confirmed.

SA alternative to Tesla Powerwall: prices, power details

South Africans do not have to wait on Tesla for a home battery system, local green energy company Freedom Won announced.

Freedom Won, a local alternative energy company based in Krugersdorp, recently unveiled its home battery system: the FreedomCOR.

“South Africans do not have to wait for home battery solutions [like the Tesla Powerwall]”, Freedom Won said in its announcement.

Like Tesla’s Powerwall, the FreedomCOR is a wall-mounted battery system that uses lithium-ion cells. Freedom Won co-founder Antony English said they use Lithium Iron Phosphate (LiFePO4) cells made by Sinopoly in China.

“FreedomCOR manufacturing is to be partially outsourced to suit demand, with final assembly and pre-commissioning by Freedom Won in Krugersdorp,” said English.

While not commercially available yet, English said 21 solar-powered systems commissioned in 2014 are using their LiFePo4 energy storage concept. These were installed in electrical boxes, or installed as an open battery.

“All are operating exceptionally well. We have sold a further six FreedomCOR systems for household backup power this year.”

English said the first FreedomCOR will be available for commercial sale in July 2015, despite their website stating a delivery forecast on orders of August 2015.

The table below summarises the sizes and prices of the FreedomCOR.

FreedomCOR Home and Business
Pack Capacity (Ah) Max usable kWh /
Max recommended daily cycling Weight Dimensions (mm) Price (excl. VAT)
100 5 / 4 kWh 63 kg 670 x 490 x 130 R32,975
200 10 / 7 kWh 116 kg 850 x 630 x 143 R57,170
300 15 / 11 kWh 169 kg 1,250 x 490 x 190 R81,653
400 20 / 14 kWh 222 kg 1,550 x 630 x 143 R106,932
500 25 / 18 kWh 275 kg 1,330 x 1,000 x 150 R130,832
600 30 / 21 kWh 328 kg 1,550 x 630 x 215 R156,193
800 40 / 28 kWh 429 kg 370 x 560 x 1,450 R196,940
1,200 60 / 42 kWh 626 kg 370 x 836 x 1,450 R302,478
1,600 80 / 56 kWh 823 kg 370 x 1,115 x 1,450 R384,942

Any number of FreedomCOR units can be connected in parallel, though English said he doesn’t believe it will be necessary to link more than two initially.

“FreedomCOR is available in many size options to suit the application and therefore connecting more than one in parallel is not necessary, save for future expansion considerations.”

The units come with a 10-year guarantee for daily cycling, and Freedom Won offers a “second life option” by exchanging the cells for new ones, at a price.

Under this second life option, cells will be replaced using the the prevailing battery technology at the time.

“FreedomCOR is not the same as Powerwall. FreedomCOR is more suited to South African conditions where short-term load shedding backup is the first priority.”

He said their battery system can be integrated with several inverter and charge controller brands of various sizes, and can deliver significantly more power than Tesla’s product.

Freedom Won’s electric vehicle history

Wall-mounted home battery systems are not the only thing Freedom Won and Tesla have in common.

Freedom Won’s background is in electric vehicles, producing electric automobiles and boats for commercial applications.

Its main business has been eco-tourism products in the form of electric 4x4s and boats for silent game viewing in Botswana.

Other pursuits include hybrid truck systems to allow downhill power regeneration, solar-powered charging systems, and electric conversions of normal cars.

“Recently we have secured finance from Wesbank (Botswana) and Sasfin SA, for our clients, to assist them with purchasing electric vehicle conversions and alternative energy systems for their private use or their businesses,” said Freedom Won co-founder Lizette Kriel.

Any idea how many kWh a 'typical' household would require?
I admit to being quite uniformed about electricity. It's probably time for all of us to read up - Eskom has provided the inspiration

There's probably no such thing as a typical household. Some spend from 500 - 5000 on electricity a month.

Do you have prepaid, just check it every day over the month and write down the reading and how much you used that month. Or if you're lazy check it at the beginning of the month write down how much you out in that month and subtract what you started with and what you're left with. Then divide that by the number of days in the month.

The problem with the latter is it does not account for high use days such as when you're doing your laundry etc.

I use about 20kWh a day taken from my average monthly usage which is about 600 kWh a month. What this does not take into consideration is the twice a week my domestic is here doing laundry the whole day.

Considering the costs above it would seem that the new tech will, for now, merely up my green credentials. There does not seem to be a cheaper alternative to Eskom.

I know city of cape town allows for grid tie. To let you feed back info the system for credit. So an array of solar panels and a small battery bank. Would be worth the investment. Solar panels are pretty cheap these days and are generally warranties for 20 - 25 years.

I take a unit reading off my prepaid everyday.My average used to be 30 units per day.
In January this year i installed for myself a 3500 kva 48volt inverter together with 1000ah gel batteries and 2300watt solar panels.The total cost was 42g.My average consumption is now 12 units.
Based on the saving it will take anything from 3 to 5 years to recover the cost.
Loadshedding definitely not an issue anymore.
