DC SPD 2P – 500V DC / 1000V DC Surge Protection Device
Product Description
Protect your solar PV system from lightning strikes and transient voltage surges with our DC Surge Protection Device (SPD) 2 Pole, available in 500V DC and 1000V DC models. Specifically engineered for photovoltaic (PV) systems, this Type II SPD provides reliable protection for solar panels, combiner boxes, charge controllers, hybrid inverters, battery energy storage systems (BESS), and other DC equipment.
Designed for fast surge suppression, the SPD diverts damaging overvoltage safely to earth, helping to prevent equipment damage, reduce downtime, and extend the lifespan of your solar installation.
Its compact 2-Pole DIN Rail design allows for quick installation in DC distribution boards and combiner boxes, making it an essential safety component for residential, commercial, and industrial solar power systems.
