Product Introduction

Engineered with plastic or metal housing, the device offers flexibility: plastic reduces material costs for budget-conscious projects, while metal enhances durability and EMI shielding in harsh environments. Compliant with EN50022 and DIN46277-3 standards, it ensures global safety and reliability, minimizing installation risks and liability.

A 25ns time constant guarantees ultra-fast response, diverting surges before equipment damage occurs. This efficiency extends the lifespan of solar inverters, panels, and batteries, reducing long-term replacement costs. The IP20 rating protects against dust and accidental contact, ensuring stable performance in indoor electrical cabinets.

With OEM/ODM customization, NSPV tailors designs to specific needs—whether adjusting voltage ratings, housing materials, or mounting options. This adaptability streamlines procurement, avoiding over-engineering and excess spending.

By integrating cost-effective materials, rapid protection, and compliance, the NSPV SPD delivers a perfect balance of affordability and security, meeting diverse client demands while safeguarding solar investments for decades.

FAQ

What is the difference between AC and DC SPDs?

AC SPDs protect alternating current systems (e.g., grid-tied inverters), while DC SPDs shield direct current circuits (e.g., solar panels to inverters). The NSPV SPD supports both via configurable protection modes.

How often should the SPD be replaced?

Replace the SPD after a major surge event (indicated by status LED/alarm) or every 5-10 years, depending on environmental conditions.

Can the SPD be installed outdoors?

The IP20 rating suits indoor use. For outdoor applications, install the SPD inside a weatherproof enclosure or opt for higher IP-rated variants (customizable via OEM).

What is the warranty period?

NSPV offers a standard 2-year warranty, extendable up to 5 years under OEM agreements.

Does the SPD support parallel operation?

Yes, multiple SPDs can be paralleled for increased current handling, but proper coordination is required to avoid uneven load distribution.

How to select between plastic and metal housing?

Choose plastic for cost efficiency and corrosion resistance in dry environments. Opt for metal in industrial settings requiring EMI shielding or physical impact resistance. The NSPV Solar DC/AC SPD delivers a future-ready surge protection solution, combining speed, versatility, and compliance to secure solar investments worldwide.
