It is also known as grid-tied systems. We Helio Navitas provide services like Installation and AMC Services in which electricity produced by solar flows to the grid through an inverter, converts DC energy to AC. The grid is acting like a virtual battery that stores energy & this energy will be utilized by the load ( electrical equipment) as & when required. This is done through import-export bidirectional meter through net-metering. The bidirectional meter records the net energy consumption, so net energy will only be charged to the customer.
This system will work only when the grid supply is available.
