Tesla is famous for producing some of the fastest (and best looking) electric vehicles on the market, but last year it revealed its home power systems in the form of Tesla Powerwall.

If you’re not familiar with it, the Powerwall couples a lithium-ion battery to solar panels, which can easily keep a small house going when the power goes out, depending on the size of the battery’s capacity.

Several renewable energy suppliers in South Africa stated that they would be stocking Powerwall units, but it turns out that there’s little demand locally for the bigger 10kWh unit.

Tesla will now only focus on one model, the smaller 7kWh unit.

“We have decided to focus entirely on building and deploying the 7kWh Daily Powerwall at this time,” Tesla explained.

As it turns out, people don’t feel that they need to install a unit that is only rated for 500 cycles and needs to be charged weekly, which are the tech specs and requirements for the 10kWh unit.

The smaller unit, on the other hand, has a 10 year guarantee and is intended for daily use off the grid, unlike the 10KWh unit, which is positioned primarily as a back-up unit.

If you want more juice for your house, Tesla recommends that you install more units, together.

“Each Powerwall has a 6.4 kWh energy storage capacity, sufficient to power most homes during the evening using electricity generated by solar panels during the day. Multiple batteries may be installed together for homes with greater energy needs.”

Tesla’s discontinuation of the larger model shouldn’t really impact South African users though, as both Dako Power and Rubicon Renewables they only plan on stocking the smaller unit.
