What is a DC surge protection box used for?

A surge protection box protects the direct current (DC) part of your PV installation (panels → inverter) against transient overvoltages. It extends the lifespan of the equipment and reduces the risk of damage during storms.

AC vs DC — what's the difference?

DC boxes protect the photovoltaic chain on the direct current side. AC boxes (also called ac boxes) protect the alternating current part (inverter output → panel/network). Depending on your configuration, you may need both.

Compatibility & installation

• Ensure that the DC voltage of your string ≤ 600 VDC and the current ≤ 16 A.
• MC4 connectors for quick and safe implementation.
• IP65 enclosure: possible outdoor installation (excluding immersion).
• Respect the wiring distances, grounding, and installation direction.

Quick FAQ

When to choose a DC surge protection box?

In the presence of storm risk, long lengths of outdoor cables, or to secure expensive equipment (inverter, panels).

What is a type 2 surge protector?

An SPD device designed to discharge the most common transient overvoltages on residential/commercial installations.

Can it be installed outside?

Yes, the enclosure is IP65. Protect it from impacts and direct rays if possible.
