Buying a PV surge protection device from a reliable supplier is very important to ensure longevity and safety for photovoltaic systems. Such surge voltages-that also include lightning, grid fluctuation, and electrical switching-capable of giving extreme damage to the critical components will be handled by the high-quality SPD. For systems rated at about 600V for residential or up to 1500V for commercial installations, the proper selection of SPD specifications will help contribute to avoiding costly equipment damage and reducing burdens related to maintenance.
Many specialized online solar equipment providers offer SPDs of various ratings, matched to system needs. Look for devices that comply with international standards such as IEC 61643-31 to ensure they will be rated for high-voltage PV systems and protection reliably. Often, solar equipment suppliers test SPDs for fast response time, usually in nanoseconds, which is important in saving sensitive components like inverters from destruction. Buying SPD from a known and good vendor will ensure that the device diverts surges effectively without systems failure.
Other than online stores, solar electrical supply companies offer SPD with a warranty that may vary between one to five years to ensure product quality. In areas where installations may be affected by lightning or fluctuations of electricity, warranty covers manufacturing defects, thus saving replacement cost. Indeed, some suppliers provide technical support in selecting the proper SPD size and voltage for choosing an SPD against a particular system to avoid problems such as under-specification in selecting an SPD that may lead to equipment damage.
Specialized suppliers, such as the PV Surge Protection Device, provide quality products for PV systems to buyers in search of reliable performance. Many vendors will often give detailed specifications of their products, expedite shipping options, and customer support in order to ensure a given SPD provides the system with its protective requirements. A secure source of PV SPDs will contribute not only to stability at the system level but also to the safety standards that are in place to assist in efficient, long-lasting solar energy production.
