The scenario
A commercial facility uses 100 kW rooftop solar PV and a 200 kWh battery energy storage system to reduce peak demand. The SLD connects utility, PV, BESS, and three facility load groups on a 480V main bus with dedicated breakers.
What is in this drawing
Read the decisions behind it.
01
Connect utility revenue meter and main breaker before the 480V main bus
02
Tie PV and BESS to the main bus through dedicated feeder breakers
03
Group loads as HVAC, production line, and lighting/receptacles for clarity
Use for documenting grid-tied commercial solar-plus-storage systems focused on peak demand reduction or demand charge management.
