  Why You Need This DC SPD

  This Surge Protection Device safeguards your solar inverter, batteries, charge controllers, and panels from dangerous voltage spikes caused by:

  • Lightning strikes

  • Grid disturbances

  • Inductive loads

  • Switching surges

  A single surge can destroy expensive equipment — this 40kA SPD absorbs and diverts the surge before it reaches your system.

   

  Frequently Asked Questions (FAQ)

  1. What is a DC SPD (Surge Protection Device)?

  A DC SPD is a protective device designed to shield your solar DC systems, inverters, and panels from high-voltage surges caused by lightning, switching spikes, or grid disturbances.

  ---

  2. Is this SPD suitable for solar systems?

  Yes. This model is specially designed for solar PV installations up to 1000V DC, making it perfect for inverters, charge controllers, and combiner boxes.

  ---

  3. What does 2P (2-Pole) mean?

  2P means the device protects both DC+ and DC– lines, ensuring complete surge protection for your DC circuit.

  ---

  4. What is the maximum surge current rating?

  This SPD supports 40kA maximum discharge current, which provides strong protection against high-energy lightning surges.

  ---

  5. Can I install it myself?

  If you have experience with solar electrical systems, installation is simple using the DIN-rail mounting.
  However, for safety reasons, it is recommended to have a professional electrician install it.

  ---

  6. Does it have a status indicator?

  Yes, it features an LED indicator window that shows whether the protective module is functioning or needs replacement.

  ---

  7. Are the SPD cartridges replaceable?

  Yes, the protection modules can be replaced easily without removing the entire device.
