An on-off grid inverter, also referred to as a hybrid inverter, plays a key role in solar energy systems by enabling both grid-connected and off-grid power operations. This type of inverter is designed to manage energy flows between solar panels, battery storage, and the utility grid.

In on-grid mode, the inverter synchronizes with the grid, feeding excess solar energy into the utility supply while drawing power when solar production is low. This allows users to reduce dependence on grid electricity and potentially benefit from feed-in tariffs. In off-grid mode, the inverter supplies power independently from the solar panels and battery bank when the grid is unavailable or intentionally disconnected.

Hybrid inverters also support battery storage, allowing energy to be stored during peak sunlight hours and used during evenings or power outages. Many systems offer built-in monitoring to track energy usage, solar production, and battery status in real-time.

Due to their dual functionality, on-off grid inverters are commonly used in areas where grid reliability is inconsistent or in systems designed to combine independence with backup capabilities. These inverters help optimize the use of renewable energy while ensuring a continuous power supply.
