Method for enabling monitoring of power consumption

A method for enabling monitoring of power consumption at a site, the site comprising an electrical load connected to a power source through a junction, the power source connected to the junction by an electrical conductor, a solar panel electrically connected to the junction through an inverter, the method comprising:

• electromagnetically coupling a single current sensor to the electrical conductor at a sensing position between the power source and the junction without direct electrical connection to the electrical conductor to create a current sensor signal;
• producing from the current sensor signal a sensed current signal and a sensed voltage signal;
• determining a sensed phase relationship between the sensed voltage signal and the sensed current signal;
• comparing the sensed phase relationship to a baseline phase relationship to determine the direction of current flow through the conductor;
• and
• creating a power source signal based on the direction and magnitude of current flowing through the conductor at the sensing position.
