PV disconnectors and fuse bases - the key to a safe photovoltaic installation

PV disconnectors and fuse bases are key elements of every photovoltaic installation.   They provide protection and the ability to safely disconnect the system. In our daily practice, we see a growing interest in these products. This is due to the dynamic development of the photovoltaic market in Poland. More and more companies and households decide to have their own PV installations.

Onninen offers a wide range of PV disconnectors and fuse bases. We supply products from renowned brands such as Eti, Hager, Jean Mueller and Eaton. Each of them offers solutions with different parameters and applications. Thanks to this, we are able to adapt products to the specific needs of the customer.

Types of PV disconnectors and fuse bases

Our range includes various types of safety devices for photovoltaic systems. These include:

• PV fuse switches
• Modular fuse bases for PV systems
• PV switch disconnectors
• Cylindrical fuse bases PV

Each of these products plays a specific role in ensuring the safety and reliability of the photovoltaic installation.   The disconnectors allow for quick power cut-off when needed. The fuse bases protect against overloads and short circuits. Together they create a complete protection system for PV installations.

How to select the right PV disconnectors and fuse bases?

Choosing the right security for a photovoltaic installation requires taking into account many factors. Key parameters include:

• Nominal voltage of the PV system
• Rated current of the installation
• Number of strings in the installation
• Isolation and disconnection requirements
• Environmental conditions for operating devices

Our experience shows that choosing security is often difficult for customers.   That is why we offer professional advice in this area. Our specialists will help you choose the optimal solutions for a specific PV installation. We ensure that the selected products will comply with current standards and regulations.

Many customers ask us about the differences between the different types of PV protection. Fuse switches combine the functions of disconnection and overcurrent protection. Modular fuse bases enable easy replacement of fuse links. Isolating switches ensure complete disconnection of the installation from the grid. The choice depends on the specifics of the given PV system.

In the case of large industrial installations, extensive security systems are usually used. They may include several levels of protection.   Recently, in a project for a large photovoltaic farm, we used a solution combining main disconnectors, string fuse bases and surge arresters.   This comprehensive approach ensures maximum installation safety.

Innovations in PV disconnectors and fuse bases

The photovoltaic market is developing dynamically, and PV security is evolving with it. We are observing several important trends in this field:

1. Miniaturization of devices while maintaining high electrical parameters.

2. Integration of disconnection and protection functions in one device.

3. Development of solutions for remote monitoring and control of PV protection systems.

4. Increasing resistance to harsh environmental conditions and UV radiation.

At Onninen we focus on innovative products that meet current market needs.   We work with leading manufacturers to offer our customers state-of-the-art solutions. An example is the new Hager line of PV fuse switches with remote monitoring.

We often come across questions about the possibility of modernizing existing PV installations. In such cases, we recommend replacing older protection with newer models. This allows for increased safety and efficiency of the entire system. Our specialists will advise on the optimal solutions for a specific situation.

In everyday practice we observe a growing interest in PV systems in the industrial sector.   For large installations, it is crucial to ensure reliability and the possibility of quick service.   That is why we recommend modular solutions that enable easy replacement of individual components without having to shut down the entire installation.

Onninen offers comprehensive support at every stage of the PV project implementation. We provide not only high-quality products, but also technical advice and training. Our experts will help you choose the optimal security, taking into account the specifics of the installation and the customer's expectations.
