The most common type of bidirectional power meter is known as a smart meter, which can communicate with the utility company and provide real-time data on energy usage and production. In conclusion, a bidirectional power meter is a specialized device that measures the flow of electricity in both directions.

On-Grid Solar System
The system uses solar panels to generate electricity during the day, and the excess power is fed back to the grid. In the evening, when there is no sunlight, the system draws power from the grid to meet the energy requirements of the house or commercial establishment.

Off-Grid Solar System
An off-grid solar system is a solar panel system that generates electricity, stores that power in solar batteries, and runs independently from the power grid. These systems encourage off-the-grid living, a lifestyle centered around energy independence and self-sustainability.

Hybrid Solar System
A hybrid solar system is grid-tied with battery storage. They come with a special 'smart' inverter that can transmit direct current (DC) power to and from your batteries, and channel alternating current (AC) power between the grid and your home when necessary.
