Livingston and Haven

Bosch installed a DC microgrid at the Livingston and Haven headquarters in Charlotte, NC. The DC microgrid system includes a 30 kW solar PV array, a DC power server connected to the utility grid, a Bosch energy management gateway, 40 DC lighting fixtures using Bosch DC drivers, and 2 industrial ceiling fans with DC input. A conventional 14 kW PV array with an inverter and 4 AC-lights were also installed to provide a reference AC system, to perform energy usage comparisons and to validate the DC microgrid. This was the very first Bosch DC microgrid installation and is primarily used to showcase the performance and value of Bosch’s DC microgrid system compared to an AC system.
