| Modes | Description | |||
| Grid-connected | In grid-connected mode, the battery energy storage system is connected to the grid, enabling bidirectional energy flow with the grid. | |||
| Manual off-grid | In manual off-grid mode, users can choose to disconnect the battery energy storage system from the grid, allowing independent operation. | |||
| PV smoothing mode | The PV smoothing mode integrates energy storage technology with photovoltaic (PV) power generation, addressing the issues of power fluctuation and intermittency in PV systems. Solar panels convert sunlight into electricity, with excess energy stored in the system. When power is needed, the energy storage system releases stored energy to meet demand, providing a stable power output and smoothing the injection of power into the grid through electronic control equipment | |||
| Backup mode | The backup mode uses the energy storage device as a backup power source. When the main grid power supply is unstable or interrupted, the energy storage system automatically activates, converting stored energy into electricity to provide emergency power support for critical equipment or the entire grid. | |||
| Peak-valley mode | In this mode, the system stores energy when electricity prices are low and uses the stored energy when prices are high. | |||
※Note:
* The off-grid function requires manual switching after disconnecting from the grid.
* It does not support connecting to three-phase three-wire loads; if the load is capacitive or inductive in off-grid mode, the Powercube's load capacity is within 25% of the rated power.
