PV Photovoltaic Grid Connected Cabinet Anti Reverse Current Control Cabinet

PV Anti-reverse Current Control Cabinet Anti-islanding Protection



Product Describe:


1. Distributed PV systems (residential/commercial rooftops)
Core needs: Prevent excess PV power from flowing back to the grid (anti-reverse current) and, in case of sudden grid outages, stop the PV system from continuously supplying power to the local grid (anti-islanding) to ensure the safety of maintenance personnel.
2. Microgrids and off-grid systems
Core needs: In off-grid or weak grid environments, prevent PV and energy storage systems from forming "islanded operation" due to grid fluctuations, ensure stable power supply for local loads, and avoid over-discharging of energy storage batteries or waste of PV power (preventing reverse current to energy storage systems).
3. Grid-connected PV + energy storage projects (industrial/commercial/public buildings)
Core needs: When PV generation exceeds load demand, control surplus power to be prioritized for storage in batteries (instead of flowing back to the grid) to reduce impact on the grid; in case of grid failure, quickly disconnect from the grid (anti-islanding) and switch to energy storage power supply mode.
4. PV carports and BIPV (building-integrated photovoltaics)
Core needs: PV systems in these scenarios are often integrated with building loads, requiring anti-reverse current functions to restrict reverse power transmission to the grid and, during grid failures, prevent PV modules from forming islanded power supply to local circuits within the building.

Suggestion:

1. Key Customization Points

  • Capacity:

    • Add +200mm width per 12 additional PV strings.

    • For 1500V systems, increase depth by 100mm per 1MW.

  • Climate Adaptations:

    • Desert: Anti-sand mesh (+100mm height).

    • Coastal: Stainless steel enclosure (+5% size).

    • Arctic: Double insulation (+150mm depth).

2. Smart Features (Optional)

  • Monitoring: +50mm height per IV curve scanner.

  • Safety: +100mm width for every 4 AFCI modules.

3. Cost-Saving Tips

✔ Use standard cable entry points (reduces custom machining).
✔ Opt for modular designs (easy future upgrades).

4. Critical Reminders

⚠ Max shipping width: 2500mm (oversized requires split design).
⚠ Wall-mounted limit: ≤80kg (else use floor-standing).
