Kreisel Electric introduces Li-ion home energy storage systems; 9.6 kW output for faster EV charging
Austrian manufacturer of high-performance batteries Kreisel Electric (earlier post) has introduced the MAVERO home energy storage system. The Li-ion battery packs are available in four different sizes, with usable capacity ranging from 8 kWh to 22 kWh. The casing is available in two colors and communicates all charge and discharge activities by means of LEDs. First deliveries are planned for early 2017.
MAVERO is a wall-mounted home energy storage system that stores electricity from any renewable energy source. Featuring a sophisticated design and a compact size of 105cm x 140 cm (41" x 55"), the discharge power of the system ranges from 4.8 to 9.6 kW in the voltage range from 288 to 384 V. The system enables accelerated EV charging with 100% self-generated electricity.
|MAVERO 10||MAVERO 14||MAVERO 20||MAVERO 28|
|Usable capacity||8 kWh||11 kWh||16 kWh||22 kWh|
|Charge/Discharge power||4.8 kW||9.6 kW|
|Charge/Discharge current||14 A||28 A|
|Weight||70 kg||90 kg||150 kg||170 kg|
|Dimensions (LxBxH)||1400 x 1050 x 150 mm||1400 x 1050 x 275 mm|
|Voltage range||288 V – 384 V|
|Life expectancy||20 years, 5,000 cycles (10-year guarantee)|
The efficiency rate is 96% and the space requirement is considerably lower than competitors. With an installation volume of 1.95 dm3/kWh, Kreisel said it is able to achieve 70% more capacity in roughly the same size, due to its proprietary high-performance batteries.
As one point of comparison, Tesla’s Powerwall home energy storage unit offers 3.3 kW and 92.5% round-trip DC efficiency.
The MAVERO system can be installed quickly by a single technician at relatively low costs. The modular design also offers flexible optimization based on energy needs, since additional modules can be added later. An innovative lighting design (ambient interface LED) communicates the battery level and the charge and discharge activities. Kreisel Electric also wants to break new ground in terms of the price with their new "Kreisel Energy" division. Ultimately, the retail price should be less than €700 per kWh.
MAVERO is designed to provide enough energy each day for the average household. The models MAVERO 20 and 28 have a higher capacity for more demanding applications such as charging electric cars.
