It works independently from the any utility power grid.
On grid and off grid solar system difference.
An off grid system can also be called a stand alone solar power system.
The benefit of this system is to generate a side income which would be very beneficial for consumers and provide incentives to switch to solar power.
Off grid power system does not have any connection with the grid.
Basically it is a solar power system that is off the grid thus the term off grid.
The entire electrical load will be powered by solar alone.
This drawback is converted into an advantage in the off grid solar system.
The only difference is the battery backup.
This system will create its own solar microgrid.
Off grid solar systems require specialised off grid inverters and battery systems large enough to store energy for 2 or more days.

An off grid solar energy system is not connected to the utility grid whereas an on grid aka grid tied solar energy system is connected to the utility grid.
If we now after the failure of supply from the electricity board we have to face the dark situations after having a solar system too.
Hybrid grid connected systems use lower cost hybrid battery inverters and only require a battery large enough to supply energy for 5 to 10 hours overnight depending on the application.
Rv solar kits are a grid example of off grid solar.
