About this item

  • 4 IN 2 OUT SOLAR COMBINER BOX--This solar combiner box is designed to optimize the connection between photovoltaic (PV) arrays and inverters. It supports 4 set of PV panel input and 2 set of power output, with a maximum input current of 20A per string and a maximum output current of 40A for the circuit breaker. It supports up to 80kW of power in a 1000V system. And provide overvoltage, overload, and quick disconnect functions to ensure the safety of the photovoltaic system;
  • TRIPLE PROTECTION (MCB + SPD + FUSE)--This PV combiner box is equipped with 40A DC1000V miniature circuit breaker (MCB), DC1000V 40KA Class T2 surge protective device (SPD), and 20A DC1000V fuse, forming a triple safety barrier. It enables protection against short circuits, overvoltage, overcurrent, leakage, and lightning. Meanwhile, it supports quick disconnection for easy maintenance, protecting core equipment such as PV panels and inverters from damage at the source.
  • DURABLE IP65 WATERPROOF ENCLOSURE--The solar junction box is made of high quality ABS+PC material and features an IP65 waterproof rating. It exhibits excellent waterproof, flame-retardant, UV-resistant, and anti-aging properties. The combiner box is designed with a PC transparent cover, allowing visual inspection of the switch operation status. It can operate stably in harsh environments such as indoor, outdoor, rooftop, and open-air settings, extending the service life of the equipment.
  • WALL MOUNTED COMBINER BOX--The solar combiner box comes with pre wired internal connections. Only the PV connectors, output power cables, and ground wires need to be connected. The package includes matching PV connectors, PV specific tools, ground wires, and mounting screws. Even without professional electricians, quick installation can be completed easily and conveniently.
  • APPLICATION SCENARIOS--The PV combiner box is specifically designed for grid-connected or off-grid solar systems. It is widely used in various scenarios such as solar panel arrays, RVs, yachts, household rooftops, and small-scale PV power plants. With multiple safety guarantees, it ensures the long-term safe and reliable operation of the entire PV system, making it a preferred supporting equipment for various solar power generation projects.

FAQ

What types of products does Stemora offer?


Stemora offers supplies for science experiments, microscopy, biology learning, measurement, laboratory organization, electronics, robotics, coding education, 3D printing, maker projects, and classroom activities. Available products and specifications may change over time.

Are Stemora products suitable for children?


Recommended ages vary by product. Please review the product description, manufacturer guidance, included warnings, and required skill level before purchasing. Products containing small parts, tools, electrical components, glass, or chemicals may not be suitable for young children.

Is adult supervision required?


Adult supervision is recommended for children and students, especially when using electrical components, sharp tools, heated equipment, glassware, small parts, or experiment materials. Customers are responsible for following all product instructions and safety precautions.

Can these products be used at home and in classrooms?


Many products may be suitable for classrooms, home learning, science projects, maker spaces, and hobby activities. Suitability depends on the specific product, learning environment, user experience, and intended activity.

How can I check what is included with a product?


Please review the product title, description, specifications, images, package quantity, and included-components section before ordering. Items shown for demonstration or scale in product images may not always be included.

How do I know whether an electronic or robotics part is compatible?


Check the listed dimensions, voltage, connector type, board compatibility, operating requirements, and supported platforms. Compatibility is not guaranteed unless it is specifically stated on the product page. Contact us before ordering if you need clarification.

When will I receive tracking information?


Tracking information is generally provided within 3–5 business days after an order is confirmed. In some cases, processing may take approximately 7–8 business days. Delivery may require an additional 4–5 business days after tracking becomes available, depending on the carrier and destination.

Why did my order arrive in separate packages?


Products in the same order may be shipped from different fulfillment locations. As a result, items may arrive separately and have different tracking numbers. You will not be charged additional shipping fees solely because an order is divided into multiple packages.

Can I change or cancel my order?


Contact us as soon as possible at vaioamaonaoak@gmail.com. We will try to assist, but changes or cancellations cannot be guaranteed once an order has entered processing or has been shipped.

What should I do if an item arrives damaged, defective, or incorrect?
