Off-grid inverters are power conversion devices designed for stand-alone energy systems. Their core function is to convert the direct current (DC) output from solar panels or batteries into stable alternating current (AC) to supply power to loads in areas with no grid coverage or unstable grids.
● Pure sine wave output
● Battery management (BMS)
● Multi-energy access
● Overload capability
● Isolated operation stability
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) |
