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.
Specification:
| Application Scenario | Typical Dimensions (W×H×D mm) | Capacity Range |
| Small Commercial Rooftop | 600×800×300 | ≤250kW |
| Standard Ground Power Plant | 800×1200×400 | 250kW-1MW |
| 1500V High-Voltage System | 1000×1500×500 | 1MW-2MW |
Custom Provide:
① Total DC input capacity
② Number of protection devices
③ Ambient temperature range
④ Cable entry requirements
Material:
Stainless steel, carbon steel
IP Rating:
IP54/IP55/IP65/IP66/IP67
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).
