ON GRID SYSTEM (GRID + SOLAR)
The solar PV power plant consists of solar panels that generate DC power. The DC power is fed to the Inverter for conversion to AC power. Synchronization arrangements effected through electronics provided in the Inverter ensure adequate synchronization of the power supply with Grid. These systems are used at locations where constant power is maintained through use with Grid (Electricity Connection), DG Sets or any other
DC power generated by the solar panels is fed to the Inverter and AC power is obtained as output. During the daytime the solar modules generate solar electricity and keep feeding the Inverter. Grid-connected PV systems are designed to operate in parallel with and interconnected with the electric utility grid. The primary component in grid-connected PV systems is the inverter.
Off Grid System
Off Grid systems are typically used in remote applications where utility power is not available. It is independent from the utility grid. Solar power generated is stored in batteries for use after sundown, a generator can also be used for back-up. The off grid inverter is a three-in-one system, integrating the controlling of battery charging/discharging, inverting and load dumping.
