The grid tie systems with standby generator are dependable especially if you are looking for commercial solar. Reason being having a power failure for the elongated duration is something inconceivable. Standby generators don’t let the grid system fail for a protracted period. If the solar panel installation undergoes power failure; the inverter will disconnect the solar back feed and switches on the generator automatically. Whereas in the normal grid-tie system, if the grid faces failure say for any specific reason; the whole commercial solar system is turned off.

Hence, the underlying difference between a grid-tie system with standby generator and the normal grid-tie system is its battery backup and generator backup.

The compensation package obviously has added price. Still, if you don’t want to with the package and having to replace batteries every 5 to 10 years, a generator is a cost-effective option one can steal.
