Dispositivo di Protezione da Sovratensione PV per Sistemi Solari in Corrente Continua
LEEYEE supplies PV surge protective devices for solar DC systems, including 1000V and 1500V DC Type 2 and Type 1+2 SPDs for combiner boxes, inverter DC inputs, rooftop solar, utility PV projects, and OEM buyers.
What is a PV surge protective device?
Solar PV systems are exposed outdoor electrical systems
PV arrays are often installed on rooftops, open fields, industrial buildings, and exposed outdoor locations. Long DC cable runs and nearby lightning events can introduce transient overvoltage into the DC side of the system.
Protect the inverter
The inverter is one of the most valuable parts of a PV system. A suitable DC SPD helps reduce surge stress before it reaches inverter input terminals.
Reduce downtime
Surge damage may stop power generation and increase maintenance cost. SPD protection helps improve system reliability in exposed solar installations.
Support safer system design
Correct SPD selection helps engineers build a more complete protection architecture for DC side, AC side, and communication circuits.
Type 2 vs Type 1+2 PV surge protective device
This is one of the most important selection points for PV SPD buyers. The right choice depends on lightning exposure, system design, and project protection requirements.
| PV SPD Type | Best Used For | Typical Position | Buyer Note |
|---|---|---|---|
| Tipo 2 PV SPD | Protection against induced transient overvoltage in many standard solar PV installations. | Solar combiner box, inverter DC input, DC distribution cabinet. | Common choice for rooftop solar, commercial PV, and standard DC-side surge protection. |
| Tipo 1+2 SPD PV | Higher protection requirement where lightning current discharge capability is needed. | PV installations with higher lightning exposure, external lightning protection consideration, or project-specified Type 1+2 requirement. | Better for exposed solar farms, industrial projects, and systems requiring stronger lightning surge protection. |
Choose PV SPD voltage according to the solar DC system
The PV SPD maximum continuous operating voltage must match the solar string voltage design. Do not select a normal AC SPD for PV DC circuits.
| PV System Voltage | Common Application | Recommended SPD Direction | What to Confirm Before Quotation |
|---|---|---|---|
| 600V DC | Small solar systems and some regional PV designs. | DC PV SPD matched to system voltage and wiring method. | String voltage, poles, installation position, and certification requirement. |
| 1000V DC | Common rooftop solar, commercial PV, and combiner box applications. | 1000V DC Type 2 PV SPD or Type 1+2 PV SPD if project requires higher protection. | Combiner box layout, inverter input voltage, discharge current, and quantity. |
| 1200V DC | Selected PV projects with higher DC-side design voltage. | PV SPD with suitable voltage rating and matching pole configuration. | Maximum open-circuit voltage and local electrical design requirement. |
| 1500V CC | Utility-scale solar farms and high-voltage PV projects. | 1500V DC PV SPD for inverter stations, combiner boxes, and DC cabinets. | Project specification, lightning risk level, SPD type, and short-circuit protection design. |
Where PV surge protective devices are installed
PV SPDs are usually installed close to the equipment that needs protection. In larger systems, protection may be required at multiple levels.
Protect PV string input circuits before they enter the DC distribution path.
Reduce transient overvoltage before it reaches the inverter DC terminals.
Support DC-side protection in commercial and utility PV electrical cabinets.
Used for residential, commercial, industrial, and utility-scale photovoltaic installations.

Document support
Datasheets, product photos, wiring information, quotation details, and basic technical documents can be prepared for buyers.
Application matching
We help match PV SPD models for combiner boxes, inverter cabinets, rooftop solar, and utility-scale PV projects.
How LEEYEE helps you select the correct PV SPD
For B2B buyers, the most important point is not only the SPD price. The model must fit the real solar system design.
Share your PV system voltage
Tell us whether your project uses 600V, 1000V, 1200V, or 1500V DC. This helps confirm the correct PV SPD voltage rating.
Confirm installation position
We check whether the SPD will be used in a combiner box, inverter input, DC cabinet, rooftop PV system, or solar farm.
Match Type 2 or Type 1+2 requirement
We help compare the application environment and protection requirement before selecting the SPD type.
Provide quotation and documents
LEEYEE can support datasheets, wiring diagrams, product photos, packaging information, and OEM quotation details.
PV SPD documents buyers usually need
Project buyers and OEM buyers often need more than a product photo. Clear documents help confirm whether the PV surge protective device can be used in a real solar DC system.

PV surge protective device FAQ
Un dispositivo di protezione contro le sovratensioni per fotovoltaico è lo stesso di un SPD AC normale?
No. Un SPD PV è progettato per circuiti fotovoltaici in corrente continua. I sistemi solari in corrente continua presentano un comportamento di tensione e requisiti di cablaggio diversi, quindi gli SPD in corrente alternata non dovrebbero essere utilizzati come sostituzione diretta degli SPD PV in corrente continua.
Dove dovrebbe essere installato un SPD per PV?
È comunemente installato nelle scatole di combinazione solare, vicino agli ingressi DC degli inverter o all'interno dei quadri di distribuzione DC. I grandi sistemi possono richiedere più punti di protezione.
Ho bisogno di un SPD PV di Tipo 2 o di Tipo 1+2?
Il SPD di tipo 2 PV è comunemente utilizzato per la protezione contro le sovratensioni indotte. Il tipo 1+2 può essere selezionato quando l'installazione ha una maggiore esposizione ai fulmini o quando il progetto richiede capacità di scarica della corrente da fulmine.
Come scelgo il valore di tensione?
La classificazione di tensione del SPD PV dovrebbe essere selezionata in base alla massima tensione continua del stringa o sistema PV. Le opzioni più comuni includono 600V, 1000V, 1200V e 1500V DC.
Can LEEYEE supply 1500V DC PV surge protective devices?
Yes. LEEYEE supplies PV surge protective device options for 1500V DC solar systems, including utility-scale PV projects, inverter stations, DC cabinets, and combiner box applications.
Can LEEYEE supply OEM PV surge protective devices?
