Austrian battery manufacturer Kreisel Electric has introduced the new MAVERO wall-mounted 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 system’s discharge power ranges from 4.8 to 9.6 kW, and voltage ranges from 288 to 384 V. Efficiency is 96%. (Kreisel offers a comparison with Tesla’s Powerwall, which offers 3.3 kW and 92.5% round-trip DC efficiency.)
The MAVERO system is compact (41×55 inches), and is designed to be installed quickly by a single technician. The modular design allows additional capacity to be added later.
MAVERO is designed to provide enough energy each day for the average household. The models MAVERO 20 and 28 offer higher capacity for charging EVs.
First deliveries are planned for early 2017. The retail price is expected to be under €700 per kWh.
