How does a Grid-tie Inverter Synchronize?

Grid monitoring

The grid tie inverter for solar continuously monitors the grid’s voltage, frequency, and phase using sensors and measurement circuits.

Frequency detection

It detects the grid frequency, which is typically 50Hz or 60Hz, depending on the region.

Phase-locked loop (PLL)

The inverter uses a PLL circuit to lock onto the grid’s phase. The PLL generates a reference signal that is synchronized with the grid’s phase.

Voltage regulation

This grid tie inverter regulates its output voltage to match the grid’s voltage. This is typically done using a voltage regulator circuit.

Synchronization algorithm

This inverter uses a synchronization algorithm to adjust its output frequency, voltage, and phase to match the grid’s parameters. This algorithm ensures that the inverter’s output is synchronized with the grid.

Zero-crossing detection

The inverter detects the zero-crossing point of the grid’s voltage waveform, which is the point where the voltage crosses from positive to negative or vice versa.

Output synchronization

It synchronizes its output with the grid by generating an output waveform that is in phase with the grid’s waveform. This is done by adjusting the inverter’s output frequency, voltage, and phase to match the grid’s parameters.
