Surge protective device（spd）
A DC SPD (Surge Protective Device) for photovoltaic (PV) systems is a protective device designed to safeguard PV installations from voltage surges and transient overvoltages. These surges can be caused by lightning strikes, grid switching, or other electrical disturbances. The DC SPD is specifically tailored for direct current (DC) applications, which are typical in PV systems where solar panels generate DC electricity.
Installation Considerations
Location: DC SPDs should be installed as close as possible to the equipment they are protecting, typically near the inverter or combiner box in a PV system.
Wiring: Proper wiring and grounding are essential to ensure the SPD functions correctly and safely.
Maintenance: Regular inspection and maintenance of the SPD are necessary to ensure it remains effective over time.
An AC SPD is a protective device designed to safeguard electrical systems and equipment from voltage surges and transient overvoltages in alternating current (AC) circuits. These surges can result from lightning strikes, power grid switching, or other electrical disturbances. The AC SPD is installed in AC power distribution systems to divert excess energy and prevent damage to connected devices.
