In a typical off grid solar array, solar panel power is stored in the battery. The inverter converts solar power into AC before transmitting it to appliances. The charge controller is a device that keeps the battery from overloading. Related
Most of the 3 phase inverters used for photovoktaic (PV) on grid installations can work only if there is AC voltage present. After the AC voltage disappears, the inverter is turned off due to safety reasons. I understand how the inverter can see that there is no AC before it starts working - it can easily get in sync with the AC waves.
The inverters do not start without the reference voltage and frequency, so during this islanding condition the rooftops owners cannot use their solar power generated.
The amount of power pushed to the grid is controlled by the phase of the generated voltage waveform. If it tries to advance the grid frequency, current is forced into the grid.

Inverters convert the direct current (DC) generated by your solar panels into alternating current (AC) that can be used in your home. But that's not all. Crucially for this discussion, inverters also synchronize this energy with the grid, which is why understanding 'how does a solar inverter synchronize with grid' is so important.
Safety: Synchronizing with the grid ensures that the solar power system operates safely and in compliance with electrical standards. It helps prevent backfeeding, which occurs when excess electricity from the solar system flows into the grid, posing a safety risk to utility workers. b.
Solar power is synchronized to the grid through the solar inverter. The inverter converts the direct current (DC) from the solar panels into AC, then adjusts its phase and frequency to match that of the grid. How does an inverter match grid frequency?
It can also suck power from grid or generator to charge battery. AC coupling allows a PV grid tied inverter connected in parallel with hybrid inverter output to push power into AC out to either push power through to grid or through inverter to charge battery.
