Mercedes Benz to take on Tesla in home battery storage in Australia

One Step Off The Grid

Australia’s burgeoning residential battery storage market is set to have yet another contender come September, with the release of a modular 2.5kWh lithium-ion product by prestige car maker Mercedes Benz.

Mercedes Benz Australia plans to unveil the home battery storage offering at its Melbourne headquarters in Mulgrave, along with an on-site four-car charging station, made up of the lithium-ion battery packs and solar panels.

The plan is for the company to sell the batteries to customers as a package with rooftop solar – the cost per 2.5kWh battery unit has not yet been released – through an as-yet unnamed “electricity retailer” partner.

According to Mercedes Benz German parent company, Daimler, up to eight 2.5kWh modules can be combined to make a capacity of up to 20kWh, allowing solar households to “buffer surplus… power with virtually no losses,” and increase their self-consumption to as much as 65 per cent.

The batteries have been available on the German market – where they are also sold as packages with solar by a network of sales partners – since April of this year, and according to the website have generated “tremendous interest” and numerous orders.

The move into the Australian residential energy storage market, says Mercedes head of corporate communications David McCarthy, is a natural progression, and goes hand in hand with the roll-out of electric cars: Mercedes is releasing three new plug-in hybrid EV models in Australia in July.

It also puts Mercedes into direct competition with fellow prestige EV maker, Tesla, whose 7kWh Powerwall battery was released to much fanfare in Australia in December last year.

“The future says this is one of the directions that people are going to want go in,” McCarthy told One Step Off T

he Grid on Wednesday. “It’s not enough to charge your car… people who are buying a plug-in hybrid want to know where the energy is coming from and have the ability to generate the energy and store it.”

In terms of demand for the Mercedes home battery, McCarthy said that the level of interest being shown in Australia indicated they might move a few hundred a year, but that it was “unchartered territory”, so difficult to predict.

As for EV demand, McCarthy concedes that numbers are still small in Australia, and will take a while yet to build, but that stationary storage will help move this along.

“It will take a while… for EVS to sell in greater numbers,’ McCarthy told One Step. “Incentives are only one of the issues …and where the power comes from that charges the cars is another – and this is our solution to that problem.

“A customer who wants to buy a package (EV, battery and solar) can do so,” McCarthy said. “Depending on how much you want [in kWh] it’ll be enough to charge your car, or run your house too, or even feed back into the grid. So it depends what level you want to go to.”

    This is why the Powerwall launch got so much attention.

    Musk dared to mention the price of the battery!

    Shock horror!

    Musk really is the Steve Jobs of the sustainable electricity sector. This is good, seeing other manufacturers coming into the market. Creates competition and drives down cost. Though I still think that Tesla will have the monopoly for a few years yet…

    Still, why do they keep calling these UPS-es home battery?

      As you mentioned Max i have seen larger UPS systems in the Industrial setting.

      Oh Max really. Should they call them camping battery!

    I see the news release mentioned quote; “A customer who wants to buy a package (EV, battery and solar) can do so,” McCarthy said.
    Second quote; Mercedes is releasing three new plug-in hybrid EV models in Australia in July.
    So it is a bit of a stretch to try and portray their Plug-In Hybrid models as EV’s.
    I suppose the average person will think they are looking at a BEV and not realize that an EV actually does not have an ICE at all.
    No doubt they will try and hang onto the old technology as long as possible knowing that its days are numbered for the majority of sales.
    On the other hand, yes it is natural with Australia’s high tariff rate and fantastic solar resources that putting battery storage into the market is a sensible decision.
    With Daimler’s engineering ability, i am sure they could build an excellent EV and be at the forefront of the evolution, if they so desired.

    Look it all depends on cost!

    Saw these at InterSolar Munich. Configured more like a bar fridge for under-counter in EU home than a Tesla Powerwall thin wall mounted shield design for US garage.
    There have three sections: top is electronics/bms, second and third are 2.5 kWh Li-ion batteries sourced from Smart electric car, with full cast aluminium case enclosing Li-ion batterie for fire protection. A similar design is the Solarwatt “My Reserve”.
    And a company is using new battery sleds from BMW i3 and mounting on wall for home storage.
