On-grid (grid-tied) inverters synchronize with the utility grid, allowing you to export surplus electricity through net metering, but they automatically shut down during power outages for safety. Off-grid inverters operate entirely independent of the grid, drawing power from batteries at all times. A hybrid inverter combines both, offering net metering plus optional battery backup.
On-Grid Inverters Explained
On-grid inverters are the most common choice for homes and businesses connected to the IESCO network. They allow you to reduce bills by exporting excess solar power to the grid under a net metering arrangement, but they cannot power your home during a grid outage unless paired with a battery.
Off-Grid Inverters Explained
Off-grid inverters are designed for locations with no grid connection at all, or for setups that intentionally operate independently. They rely fully on battery storage and require careful capacity planning since there is no grid to fall back on when demand exceeds generation.
Hybrid Inverters: The Middle Ground
Hybrid inverters give you the best of both — net metering savings when the grid is available, and automatic battery backup during outages. This makes them well suited to areas that experience regular load shedding. Read more about our recommendations for hybrid solar inverters.
Which One Do Twin Cities Homes Typically Need?
Since Islamabad and Rawalpindi have established grid infrastructure, most residential and commercial clients choose on-grid or hybrid systems rather than true off-grid setups. If load shedding and backup power are your main concern, our guide on the load shedding solution with solar and battery covers this in more detail.
Frequently Asked Questions
Can an on-grid inverter be converted to off-grid?
Not directly — the underlying hardware and safety design differ. Most homeowners instead choose a hybrid inverter, which is designed from the start to work with or without the grid.
Do off-grid inverters qualify for net metering?
No. Net metering requires a grid-tied connection, so only on-grid or hybrid inverters operating in grid-tied mode are eligible for IESCO net metering.
Which type is cheaper to install?
On-grid systems are generally the least expensive since they don't require battery storage, while hybrid and off-grid systems cost more upfront due to batteries and additional components.
