Dimension | On-grid Inverter | Off-grid Inverter | Hybrid Inverter |
Operating Mode | Grid-dependent | Completely independent | Automatic switching between on-grid and off-grid |
Energy Storage Configuration | No battery, excess power input to the grid | Battery required, storage of excess power | Connectable battery, support for charge/discharge management |
Switching Capability | No off-grid function | No grid-connected function | Automatic switching mode, seamless power supply |
Scenarios | Grid stabilized, need to sell power to save power areas | Remote areas with no/unstable grid | Occasional grid outages, need for backup power scenarios |
Cost | Minimum (no batteries) | Maximum (high battery maintenance costs) | Medium (batteries optional) |
