A large commercial building

Emma works for a large company and is responsible for everything related to energy. To gain maximum insight into the building's energy flows, she wants to equip all major circuits and distributions with kWh meters. The building has three floors, each with its own meter. She also wants to monitor the production of the solar panel system, the consumption of the charging station, and various other small and large consumers. A total of 12 submeters are needed. The main 250A connection is not equipped with a smart meter with a P1 port. Therefore, an indirect kWh meter is used in combination with 250A current coils to read it.
