Battle of the Battery: Tesla’s Powerwall vs AGL’s Power Advantage

Information verified correct on October 26th, 2016

In the aftermath of Tesla’s earthshaking announcement, AGL timidly announce their own home battery.

Tesla’s Powerwall vs AGL’s Power Advantage

Last week we reported on Tesla Energy’s revolutionary Powerwall announcement. The clean-energy giant plans to tackle carbon emissions head-on with an affordable, lithium-ion battery known as the Powerwall. The Powerwall will store energy generated by solar panels for load shifting and for use during a blackout. However, before we even had the chance to take a breath and soak it all in, AGL, one of Australia’s ‘greener’ energy providers, has announced their very own range of energy storage devices, tentatively named the Power Advantage.

Tesla Powerwall - What is it?

Tesla’s Powerwall is a rechargeable lithium-ion battery for storing energy at home. In their mission to wean the world off fossil fuels and achieve zero emission power generation, Tesla are teaming up with utilities and renewable energy partners around the world to improve ‘resiliency and cleanliness’ by lightening the load on the grid with energy storage options.

So, what benefits does a home battery offer?

  • Back Up Power: The Tesla Powerwall will be capable of powering essential appliances for a number of hours in the event of a blackout.
  • Load Shifting: While you’re away during the day, the Powerwall will store energy that can be discharged during peak hours. This will save customers money on their energy bill.
  • Reliance on Solar Power Generation: The Powerwall keeps a surplus energy reserve for those rainy days when the sun just isn’t shining.

What are the specifications of the Tesla Powerwall?

The Tesla Powerwall will launch worldwide in two different sizes, 7 kWh and 10 kWh. While both versions can be connected with solar or grid, both can also be used for backup power. The 10 kWh unit is optimised for this, whereas the 7 kWh version will be cheaper and primarily used for daily tasks.

  • Dimensions: H: 1300 mm W: 860 mm D: 180 mm
  • Energy: 7 kWh or 10 kWh
  • Placement: Wall Mounted Indoor/Outdoor
  • Inverter: Pairs with an expanding roster of inverters
  • Peak Power: 3.3 kW
  • Continuous Power: 2 kW
  • Round Trip Efficiency: >92%
  • Operating Temperature Range: -20°C to 43°C
  • Warranty: 10 years
  • Price: Estimated at $3800 AUD for 7 kWh and $4435 AUD for 10 kWh

What are the specifications of the AGL Power Advantage?

As one of Australia’s greener energy providers, AGL have been tossing around the idea of a home battery storage option for quite some time now, but it looks like Tesla’s recent announcement was all it took for the Australian provider to get the ball rolling as they officially announced their option, the Power Advantage, the following day. Details on AGL’s home battery alternative are pretty scarce at the moment (it was likely a rushed announcement), but here’s everything we know about the Power Advantage, so far…

  • Dimensions: H: 682 mm W: 672 mm D: 384 mm
  • Mounting: Indoor mounting
  • Energy: 6 kWh
  • Peak Power: 3 kW
  • Charging time: 80 minutes with full sunlight
  • Warranty: 5 years (designed to last 5000 cycles)
  • Price: No outright price announced (Options will be available for bundling with energy plans)

Our verdict

Right now, Tesla’s option for home energy storage looks more efficient and more economical. Top this off with a design that wouldn’t look out of place hanging on the wall in a trendy inner-city nightclub, and Tesla’s offering certainly stands out as the more desirable option. However, AGL have yet to give all the details on their Power Advantage option, and if they manage to make it cheaper (and preferably slimmer, like the Powerwall), they might just be able to lure customers in before Tesla Energy begins its heroic crusade.
