Notices

● Select the appropriate model based on the PV system's DC voltage (75Vdc~900Vdc).

● Use wiring with cross-sectional area 2.5mm²-32mm² and tighten screws to 5N·m torque.

● Install the SPD in the DC side of the PV system, close to the protected equipment.

● Ensure reliable grounding with ground resistance ≤4Ω to guarantee surge diversion efficiency.

● Regularly check the status window—replace the module immediately if it turns red (failure status).

● The product is for indoor use; avoid outdoor exposure to moisture and direct sunlight.
 

FAQ

Q1: What is the difference between LPM PV series and LPM PD series?

A1: LPM PV series supports higher DC voltages (up to 1500Vdc) for large-scale PV systems, while LPM PD series is for low to medium-voltage (75Vdc~900Vdc) PV applications.

Q2: Can this SPD be used for 12Vdc or 24Vdc solar systems?

A2: Yes, the LPM PD100 model (75Vdc Un) is compatible with 12Vdc/24Vdc solar systems, providing overvoltage protection.

Q3: Does the product have a built-in arc extinguishing mechanism?

A3: Yes, it is equipped with a built-in rotary arc extinguishing baffle to prevent arc faults during surge protection.

Q4: What is the installation method for this product?

A4: It adopts 35mm standard DIN Rail mounting, compatible with most PV combiner boxes and electrical cabinets.

Q5: What is the service life of the LPM PD series?

A5: Under normal operating conditions, the service life is 5-8 years. It may vary based on surge frequency and environmental factors.
