Introducing the New LQN Series PV Combiner Box

We are pleased to introduce our latest photovoltaic product — the LQN Series PV Combiner Box.

After a period of product development, mold design, component selection, and practical installation testing, the new LQN Series is now ready to enter the market.

With this new series, we focused on one product: a reliable, practical, and professionally designed PV combiner box for modern solar systems.

The LQN Series features a newly developed PC enclosure with an exclusive mold design, giving the product a clean and modern appearance while providing the protection required for outdoor photovoltaic applications.

A New Enclosure Design for the LQN Series

The enclosure is one of the most visible differences between the new LQN Series and conventional PV combiner boxes.

We developed the enclosure mold specifically for this series, with attention to the overall structure, component arrangement, cable entry and exit, sealing, and installation requirements.

The PC enclosure is designed for outdoor photovoltaic applications, with a focus on durability, protection, and practical installation.

Rather than simply changing the appearance, we wanted the new enclosure to work together with the internal electrical configuration as a complete product.

This gives the LQN Series a distinctive appearance while maintaining the functionality expected from a professional PV combiner box.

Designed Around the PV System

The LQN Series is available in different configurations according to the requirements of the photovoltaic system.

Depending on the application, the combiner box can integrate PV fuses, DC circuit breakers, DC isolators, surge protection devices, busbars, PV cables, and PV connectors.

The internal components are selected according to the electrical configuration and are tested for compatibility as part of the complete combiner box system.

The objective is straightforward:

The components inside the box need to work together as one system.

For projects using different solar panel configurations or inverter specifications, we can also adjust the configuration accordingly

LQN Series — Main Configuration

*Protection level depends on the specific model and configuration. Please refer to the corresponding product specification sheet.

Application in Solar PV Systems

The LQN Series is primarily designed for the DC side of photovoltaic systems, connecting multiple PV strings before the inverter.

A typical system configuration can be illustrated as:

PV Modules → LQN Series PV Combiner Box → Inverter → AC Distribution → Load / Grid

The combiner box provides a centralized location for PV string connection and DC-side protection, helping simplify system wiring and maintenance.

The LQN Series can be used across a range of applications, including:

• Residential solar systems
• Commercial and industrial PV systems
• Rooftop solar projects
• Off-grid photovoltaic systems
• Agricultural solar installations
• Solar projects using string inverters
• Customized photovoltaic projects

The actual configuration can be selected according to the number of PV strings, system voltage, current, inverter specifications, and local installation requirements.

Compatible With Different Inverter Configurations

Different solar projects use different inverter brands and system configurations.

The LQN Series can be configured according to the requirements of major inverter manufacturers, including Deye and other mainstream inverter brands.

For a new project, customers can provide the inverter model, PV module specifications, number of strings, system voltage, and current requirements.

Based on these parameters, we can recommend the corresponding LQN Series configuration.

Built for Different Markets and Project Requirements

Another feature of the LQN Series is its configuration flexibility.

The enclosure dimensions, cable interfaces, internal component arrangement, protection devices, and other details can be adjusted according to the project.

This is particularly useful for customers who have specific installation requirements or need a customized solution for their local market.

For OEM and ODM projects, we can discuss the required enclosure size, mounting holes, cable entry positions, internal layout, electrical components, and labeling.

In this way, the LQN Series can be developed around the customer's actual PV system rather than being limited to a single standard configuration.

Now Available for the Market

The LQN Series will officially enter the market in mid-September 2026.

We are now accepting inquiries for standard configurations as well as customized projects.

If you are currently sourcing PV combiner boxes for a new solar project, distributor inventory, or OEM/ODM cooperation, you are welcome to contact us.

Send us your inverter model, PV panel configuration, number of strings, system voltage, or your existing specification.

Our team can review the requirements and provide the appropriate LQN Series configuration, technical information, and quotation.
