Key Selection Points for Photovoltaic SPDs: Avoiding "Mismatch" Leading to Protection Failure

(1) Voltage Level Compatibility (Core Parameter, Mismatch is Not Allowed)

• DC-side SPD: Rated voltage Uc ≥ 1.1 times the maximum operating voltage of the system (e.g., for a 1500V system, select an SPD with Uc ≥ 1650V DC), 

• clamping voltage Ucp ≤ 80% of the equipment insulation withstand voltage;

• AC-side SPD: Rated voltage Uc ≥ the highest voltage of the power grid (e.g., for a 400V system, select an SPD with Uc ≥ 440V AC);

• Signal-side SPD: Rated voltage matches the operating voltage of the communication line (e.g., for RS485 lines, select Uc = 12V/24V). 

(2) Current Capacity Selection (Based on Lightning Risk Level)

• High-incidence lightning areas (≥40 thunderstorm days per year): Type 1 SPD with Iimp≥25kA, Type 2 SPD with Icn≥40kA;

• Ordinary areas: Type 1 SPD with Iimp≥12.5kA, Type 2 SPD with Icn≥20kA;

• Centralized photovoltaic booster stations: Type 1 SPD with Iimp≥50kA is required to cope with strong lightning surges.

(3) Response Time and Structure Selection

• Response Time: ≤25ns (nanosecond level) to ensure clamping is completed before surge energy enters the equipment;

• Structure Type: DC side selects "unidirectional/bidirectional" SPD (energy storage systems must select bidirectional), AC side selects 3+1 pole (L1/L2/L3/N→PE), outdoor installation selects IP65 or higher protection level. 

(4) Compatibility Requirements

• Compatibility with fuses/circuit breakers: A dedicated fuse (rated current ≤ 80% of the maximum withstand current of the SPD) must be connected in series at the front end of the SPD to prevent fire caused by SPD failure;

• Compatibility with inverters: Select a low residual voltage SPD to avoid the inverter from falsely triggering overvoltage protection due to excessive clamping voltage.

Technical data

Common Misconceptions Corrected: These Misconceptions Can Lead to Protection Failure

• "PV modules have glass casings, so they're not afraid of surges": The module glass only protects against physical impacts and cannot block voltage surges. The junction boxes and bypass diodes inside the modules are extremely sensitive to surges.

• "An AC-side SPD is enough": DC-side surges account for 70% of surge incidents in PV systems. Only AC-side protection will lead to frequent damage to the inverter's DC input and the modules.

• "The SPD's rated voltage only needs to equal the system voltage": Voltage fluctuations may occur during system operation (such as an increase in module open-circuit voltage). A 10%-20% margin is required; otherwise, the SPD may malfunction or burn out.

• "If the grounding resistance meets the standard, there's no need for an SPD": The grounding system can only discharge part of the surge energy and cannot clamp transient overvoltages.It must work in conjunction with an SPD to achieve comprehensive protection.

• "An SPD is a one-time solution": The MOV element of the SPD will gradually age with surge impacts and needs to be inspected and replaced regularly; otherwise, it will lose its protective capability.

   
Reliable Surge Protection with the 40kA DC Surge Protector for Your Solar System

   
When it comes to protecting your solar system from unpredictable electrical surges, the 40kA DC surge protector is an essential component that guarantees long-lasting, efficient performance.

Why Choose DC Surge Protection Type 2 for Your Solar System?

   
When selecting a surge protector for your solar installation, it's important to consider the protection level, and that's where DC surge protection type 2 becomes essential. Unlike Type 1 surge protectors, which are primarily designed for high-risk areas with frequent lightning storms, DC surge protection type 2 is perfect for systems that are exposed to moderate surge events. This makes it an excellent fit for most residential and commercial solar installations, where surge events are not as frequent but still pose a significant risk to equipment.

   
The 40kA DC surge protector offers the necessary surge handling capacity to keep your solar system running smoothly, preventing damage to critical components such as the inverters and PV modules. By using the DC SPD 1000V, you ensure that surges, which may otherwise cause system downtime or expensive repairs, are effectively absorbed and diverted away from the system.
