Chinese inverter maker GoodWe has unveiled two new household batteries that supposedly can automatically identify parallel solar panels without the need for a rotary dial.
A first new low voltage device called Lynx Home U seriess is available in three different devices with storage capacities of 5.4, 10.8 and 16.2 kWh and a weight of 60, 120 or 160 kg. The dimensions of the first unit are 480 x 175 x 570 mm and those of the second device 960 x 175 x 570 mm. The largest battery has a size of 1,440 x 175 x 570 mm.
The battery has a nominal voltage of 51.2 V, uses LiFePO4 as the cathode material and has a depth of discharge of 90%. The systems have an ambient temperature range of -10 degrees Celsius to 50 degrees Celsius as well as a 10-year performance guarantee and a five-year product guarantee.
A second high voltage battery, synchronized Lynx Home S seriesis available in five versions with storage capacities from 7.68 to 20.48 kWh and a nominal voltage from 153.6 to 409.6 V. The smallest device has a weight of 126 kg and a size of 610 x 226 x 1,170 mm and the largest weighs 311 kg and measures 1,220 x 226 x 1,445 mm. All high-voltage batteries should have an ultra-fast charge rate of one hour and a performance guarantee of 10 years.
Both products are IP65 protected and can be installed on the wall or on the floor. They should also be able to restart automatically if the battery switches to self-protection mode due to undervoltage.
"Both models of the GoodWe Lynx Home series have remote diagnosis and updating and support the simultaneous updating of all modules via remote access," explained the manufacturer. "The battery is also equipped with automatic module recognition."
