PV fuse links

PV fuse links - protection of photovoltaic installations

PV fuse links are a key element in securing photovoltaic systems.   They protect installations against the effects of short circuits and overloads. Our offer includes a wide selection of PV inserts. Various types and parameters are available. We select them for specific customer needs. Our consultants will be happy to help you choose the right protection.

We often come across questions about the differences between types of PV inserts. So let us explain that there are two main types. These are cylindrical inserts and blade inserts. Each type has its advantages. Cylindrical inserts are compact and easy to install. Blade inserts work well at higher rated currents. The choice depends on the parameters of the specific installation.

Types of PV fuse links available from Onninen

Our range includes high-quality PV fuse links. We offer products from renowned brands. These include our own brands: Onnline and Opal. Links from other leading manufacturers are also available.   We especially recommend PV cylindrical fuse links.   They are widely used in photovoltaic installations. They are available in various sizes and with various parameters.

PV 2A-16A/1000V DC cylindrical inserts are a popular choice for our customers. They work well in small and medium-sized installations. For larger systems, we offer inserts with higher rated currents. Our specialists will help you choose the right type for your specific project. They will also advise on proper installation and operation.

Criteria for selecting PV fuse links

When selecting PV fuse links, several key parameters should be considered. The most important of these are the rated current and rated voltage. The time-current characteristic is also important.   The selection of inserts must take into account the specific operation of the photovoltaic installation.   Current fluctuations due to variable solar radiation are important. The possibility of reverse currents must also be taken into account.

In our daily practice, we encounter various design challenges. Recently, during the implementation of a large photovoltaic farm, we used special inserts. They were resistant to high operating temperatures. They provided stable protection despite changing weather conditions. This shows how important it is to select the right protection.

PV fuse links must meet a number of standards and requirements. Certificates confirming their parameters are key. Our offer includes only proven products. They have the necessary certificates and approvals. This guarantees their reliability and safety of use.

1. Determination of the rated current of the PV installation
2. Selecting the appropriate rated voltage of the fuse link
3. Time-current characteristic analysis
4. Taking into account the working environment conditions
5. Checking compliance with standards and certificates

Practical applications of PV fuse links

PV fuse links are used in various elements of the installation. They protect individual strings of photovoltaic panels. They also protect inverters and other system devices.   Correctly selected inserts provide protection against short circuit and overload currents.   They increase the safety and reliability of the entire photovoltaic installation.

In the case of modernization of existing PV installations, we often recommend replacing the inserts. New models offer better parameters and higher reliability. Many customers ask us about the possibilities of optimizing protection. In such cases, we advise a comprehensive analysis of the system. This allows us to select the optimal protection solutions.

Our experience shows that the quality of PV fuse links is very important. It affects the long-term performance and safety of the installation. That is why we recommend products from proven brands. They provide the highest standards of protection. They minimize the risk of failures and downtime in the operation of the photovoltaic system.

At Onninen, we offer comprehensive support in selecting PV protection. Our specialists analyze the customer's needs and installation parameters. On this basis, they recommend optimal solutions. We also provide training in the installation and operation of PV inserts. Thanks to this, our customers can fully use the potential of these products.
