DC distribution system

The figure shows the simplified distribution system of the DC microgrid system. The wire sizing has to comply with the South Africa National Standard (SANS) on the wiring of premises 6 mm2 for the generation and storage side, and 2.5 mm2 for the distribution side will allow an acceptable tolerance of voltage drop for this low voltage system, refer to SANS 10142
