HYBRID Solar System
Hybrid Solar System operates in both conditions(presence/absence of main grid). Hybrid inverter has ability to decide when to connect/disconnect from the grid and when to charge/discharge the batteries.
On Grid Solar System
On-grid System generates electricity from PV panels in the presence of main utility. On-grid inverter derive the load from Solar first and excess power can sell out to grid.
Off Grid Solar System
This type of system usually installed in areas where main grid is not easily available. DC power from PV Panels is stored in batteries and converted to AC power by Off-grid inverter.
