For detailed instructions on parallel connection, including wiring diagrams and configuration steps, please consult the comprehensive user manual provided with your inverter. Proper communication cabling and settings are crucial for stable parallel operation.
9. Battery-Free Operation
This hybrid inverter supports battery-free operation, allowing it to be powered directly from photovoltaic (PV) modules to supply alternating current for homes or other loads without the need for batteries. This feature offers greater flexibility in system design and can reduce initial investment or battery usage.
9.1 How Battery-Free Operation Works:
- Direct PV Power: The inverter directly converts DC power from the PV modules into AC power for connected loads.
- Grid-Assisted Supply: If PV generation is insufficient to meet load demand, the system can draw energy from the grid to ensure continuous power supply.
9.2 Napredtages:
- Znižani začetni stroški: Operate the system without batteries initially, adding them later if needed.
- Improved System Flexibility: Direct use of solar power during peak generation, reducing grid dependence.
- Reduced Battery Loss: Extends battery life by skipping battery usage when solar power is abundant.
9.3 Limitations and Precautions:
- No Power Supply at Night: In battery-free mode, there is no power supply from the inverter at night or on cloudy days if there is no grid access.
- PV Generation Fluctuations: Load power supply may be affected by unstable solar generation (e.g., cloudy weather).
9.4 Applicable Scenarios:
- Daytime peak electricity users.
- Industrial and agricultural pumping stations in areas with sufficient sunlight.
