China-based technology giant BYD has installed the first of its residential high-voltage B-Box energy storage systems in Germany and is aiming to launch the system into the US later this year.

The German installation included nine modules with a combined capacity of 11.52kWh. Utilising its modular design, the storage system can have up to five systems connected in parallel in one location.

The firm will target east and west coast states inthe US, as well as Hawaii, where electricity prices are high, and grid constraints make storage applications attractive. The firm launched the B-Box in the UK 12 months ago.

In July, BYD also announced a tie-up with the inverter manufacturing division of Kostal, where the former’s latest high voltage energy storage systems would be paired with the latter’s PIKO brand inverters.

BYD has also won its largest ever solar module supply contract for 170MW of NextEra Energy solar projects in the US.

Zhao added that BYD is in discussions with several international companies about introducing EV-charging infrastructure and other clean energy solutions. Indeed, this week the company also signed an agreement with the United Nations Environment Programme (UNEP) to promote electric mobility.
