Polycab Ongrid Inverter

Polycab Solar Grid

Tie String Inverters

Our solar grid-tie inverters are used to convert direct current (“DC”) power generated from solar energy through the solar panel, into alternating current (“AC”) power. It adjusts the voltage levels according to the grid voltage for synchronization with local grid supply. The solar grid-tie inverters feed the generated power to the load, and excess power is exported to the grid, facilitating Net Metering. The solar grid-tie inverters are used for solar on-grid projects only.
