TYPES OF PV SYSTEMS

THERE ARE FOUR TYPICAL CONFIGURATIONS FOR RESIDENTIAL AND COMMERCIAL PV SYSTEMS

Grid-tied feed in PV systems have PV panels that are connected directly to an inverter. The electricity it generates is used locally on the property or fed back into the electricity grid, when excess electricity is generated
Grid-tied hybrid PV systems are able to disconnect the incoming supply and connect the load to the PV system or stored energy in batteries. These systems can operate in load-shedding scenarios.
Grid-tied PV systems with reverse power blocking provide electricity to the property when there is a demand for it, but blocks any excess electricity generated from feeding back onto the grid.
Standalone or off grid PV systems usually have batteries and a charge controller. The system feeds electrical circuits on the property that are wired completely electrically separate of the electricity service provider’s grid.
