Product Introduction

The NSPV EC03 PV junction box is a premium choice for solar installations, offering exceptional performance and reliability. With two robust configurations, it caters to diverse power needs: Option A supports a max current of 15A (diode 20A) at a rated DC voltage of 1000V, while Option B handles up to 20A (diode 30A) at 1500V DC. Both feature a typical contact resistance of ≤0.25 mΩ, ensuring minimal power loss and optimal efficiency.

Constructed from durable PA/CU materials, the NSPV EC03 boasts excellent UV and water resistance, with IP65 and IP67 ratings providing dustproof and waterproof protection. This enhances longevity, reducing maintenance costs and downtime. Its cost-effectiveness stems from its efficient design, which minimizes energy waste and extends system lifespan.

Safety is paramount, with the junction box meeting TUV and IEC standards, ensuring compliance with international safety benchmarks. Its straightforward operation and easy access for inspection and maintenance simplify upkeep, making it an ideal solution for both residential and commercial solar projects seeking reliability, cost savings, and superior safety.

Product Specifications

The NSPV EC03 comes in two configurations to cater to varying power requirements:
Option A	This variant supports a maximum current of 15A (with a diode rated at 20A) and is designed for a rated voltage of DC 1000V. Its IP65 rating ensures robust protection against environmental elements.
Option B	For higher power applications, this version can handle a maximum current of 20A (with a diode rated at 30A) and operates at a rated voltage of DC 1500V. This option also boasts an IP67 rating for superior ingress protection.
Both options feature a typical contact resistance of ≤0.25 mΩ, ensuring minimal power loss and optimal efficiency. The junction box accommodates 4mm² (12AWG) cables, facilitating easy integration into various solar setups.

Our Features

Tailored solutions are available to accommodate different sizes of photovoltaic (PV) panels:

For Small PV Panels: Utilize the EC03MT junction box, featuring a single central junction box with positive and negative output wires extending from the left and right sides, respectively.
·For Medium PV Panels: Employ a combination of EC03N and EC03P junction boxes, with one wire extending from each side, designated as Negative (EC03N) and Positive (EC03P).
For Large PV Panels: Opt for the EC03N + EC03P + EC03MT configuration, which includes bypass diodes within the EC03MT unit to enhance performance and reliability.
For New-Generation PV Panels: Choose the enhanced setup of EC03N + EC03P + EC03MT *2, providing double the capacity and flexibility for advanced photovoltaic applications.

FAQ

What is the difference between IP65 and IP67 ratings?

The IP (Ingress Protection) rating indicates the level of protection an enclosure provides against the intrusion of solid objects and liquids. IP65 means the box is dustproof and protected against water jets from any direction, while IP67 offers the same dust protection but is also resistant to immersion in water up to 1 meter for 30 minutes.

Can the NSPV EC03 be used in high-temperature environments?

Yes, the NSPV EC03 is designed to withstand high temperatures and is constructed from materials that resist degradation under extreme conditions, ensuring reliable performance even in hot climates.

Is the NSPV EC03 compliant with international standards?

Absolutely, the NSPV EC03 is designed to meet TUV and IEC standards, ensuring it adheres to the highest safety and performance benchmarks in the industry.
