A Mercedes-Benz personal power storage plant is set for launching at the Intersolar Expo in Munich, Germany this week. Daimler AG on Tuesday unveiled this portable power unit, which is based on Mercedes technology, for residential and business uses.

These private energy storage units have a total of eight battery modules, each with an energy content of 2.5 kWh, and designed to supplement the energy needs of households that rely on solar power. All eight storage units can be combined to produce an overall capacity of 20 kWh. Industrial modules come with a higher capacity that is 5.9 kWh.

Like the Mercedes-Benz private storage cells, its US counterpart Tesla Powerwall is also modular. Tesla first introduced home battery in April this year with each module either in 7 kWh or 10 kWh. The 7 kWh cells can be combined to produce a capacity of 90 kWh, and 63 kWh for the 7 kWh packs.

Daimler AG will present these personal energy storage units at the Intersolar Expo, which runs from June 10 to June 12. The company takes prides in the proven worth of the technology it uses, and for that it is confident that it can also deliver the same "best credentials for stationary use."

Tesla has already received 38,000 pre-orders for its home battery, making Tesla Powerwall sold-out until mid-2016. The company aims for an expansion via a $2 billion investment for its battery Gigafactory outside Reno, Nev. Daimler AG might do the same to satisfy demands and make these units available in useful numbers.

Meanwhile, the Mercedes-Benz storage power plant is currently offered through an online reservation. Delivery of Mercedes batteries will start in September.

Using home batteries like that of Mercedes-Benz personal storage plants and Tesla Powerwall in homes and businesses can increase the viability of distributed solar power generation as well as make maintenance of electric vehicles easier. These companies claim that a widespread adoption of home batteries can potentially transform the utility industry, especially that these units can store energy through other sources, not only solar.
