The On-grid system is connected with utility gird (Like KSEB of Kerala or BESCOM of Bangalore) and this system would work only if grid is available. In case of a power cut, the system will not work hence the on-grid system is also termed as Grid Tied System. Grid is required since the inverter needs to be provided with reference voltage and inverter needs to sync with grid in order to export energy back into grid On grid System Makes Sense for locations with no daytime power cut or with less than 2 hrs of daytime power cut. This type of system is apt for reducing your electricity bill since it is cheaper than a battery-based system and there is no recurring cost of replacement of components
