This innovative product is designed to enhance the safety and performance of photovoltaic (PV) systems by offering reliable protection for solar power strings and inverters. With increasing global demand for solar energy, efficient protection mechanisms are more critical than ever, and Sowellsolar’s PV String Fuse is poised to meet these needs.

The 1000V PV String Fuse is a high-performance component that ensures the safety of your solar power systems by preventing damage due to overcurrent or faults within the photovoltaic strings. It is ideal for use in both residential and commercial solar installations, offering superior protection for the entire system.

Key Features of the 1000V PV String Fuse

1. High Rated Voltage and Current Capacity

The PV String Fuse is designed to operate at a rated voltage of 1000V, making it suitable for use in a wide range of high-voltage photovoltaic systems. With an optional fuse current rating of 15A, 16A, 20A, 25A, 30A, and 32A, this fuse provides flexibility to accommodate different system requirements. Whether you need a lower current for smaller systems or a higher current for more robust setups, Sowellsolar’s PV String Fuse can handle it all.

2. Versatile Fuse Holder for Enhanced Safety

The PV String Fuse Holder is engineered to be compatible with voltages up to 1000V and is suitable for a wide range of wire sizes, from 4 AWG to 17 AWG. This makes the fuse holder a highly adaptable component for various solar installations. It also complies with international standards such as IEC60947-3 and EN60947-3 for the fuse holder, and IEC60296-6 and EN60296-6 for the fuse itself, ensuring the product meets global safety and quality requirements.

3. Compact and Durable Design

The fuse itself has a size of Φ10X38mm, designed to fit easily into most solar systems without taking up too much space. It is built with durability in mind, ensuring that it can withstand harsh environmental conditions typically found in outdoor solar installations. The robust construction of the fuse holder also ensures longevity and reliability.

4. Efficient Power Dissipation

The PV String Fuse offers 4.5W of dissipated power, ensuring that heat generated during operation is effectively managed, minimizing the risk of overheating and ensuring the safety of the entire system.

The Role of the PV String Fuse in Solar Power Systems

In a typical photovoltaic system, multiple solar panels are connected in series to form PV strings. These strings are then linked together to power inverters, which convert DC power to AC power. However, if one of the panels in a string fails, or if there is a fault that causes an overcurrent, it can damage the inverter and other panels connected in parallel.

The PV String Fuse is connected in series with each string of photovoltaic modules. In the event of a fault, such as an overcurrent caused by a malfunctioning panel or a short circuit, the fuse will blow, interrupting the current and protecting the inverter and the rest of the system. This protection ensures that your solar installation continues to function safely and efficiently, even if there is a fault in one of the strings.

Selectable Fuse Current Options for Flexible Application

One of the standout features of the Sowellsolar 1000V PV String Fuse is the range of current options available. With selectable fuse currents of 15A, 16A, 20A, 25A, 30A, and 32A, users can tailor the protection according to their specific needs. Whether you are working with smaller, low-power systems or larger, high-capacity solar arrays, Sowellsolar’s PV String Fuse provides the flexibility to choose the optimal current rating.

Each fuse option provides protection for the maximum current capacity, ensuring that the photovoltaic strings are safeguarded without prematurely blowing the fuse under normal operating conditions. This versatility makes the fuse suitable for a wide range of solar installations, from residential rooftops to large-scale commercial solar farms.

Compliance with International Standards

The 1000V PV String Fuse has been designed to meet IEC60947-3 and EN60947-3 standards for the fuse holder, as well as IEC60296-6 and EN60296-6 standards for the fuse itself. These certifications ensure that Sowellsolar’s product meets the highest international quality and safety standards, providing customers with peace of mind regarding its reliability and performance.

These standards are crucial for ensuring the fuse can operate safely in various environmental conditions, from extreme heat to heavy rain, making the PV String Fuse suitable for both domestic and commercial installations across the globe.

Enhanced Solar System Protection

By installing the 1000V PV String Fuse, solar system owners can benefit from enhanced protection for their photovoltaic strings and inverters. The fuse effectively shields the system from electrical faults and overcurrent, preventing costly damage to the expensive components of the solar installation.

Sowellsolar’s 1000V PV String Fuse offers an essential layer of security for solar power systems, ensuring the longevity and reliability of both the modules and the inverter. Whether you're upgrading an existing system or planning a new installation, this fuse is an excellent choice for protecting your valuable solar infrastructure.

How the PV String Fuse Holder and Fuse Work Together

The PV String Fuse Holder is designed to hold the Φ10X38mm fuse in place, ensuring a secure connection between the fuse and the photovoltaic system. It is easy to install, with a simple mechanism for inserting the fuse into the holder, making it user-friendly for installers. The holder is also equipped to handle the selected fuse current ratings of 15A, 16A, 20A, 25A, 30A, or 32A, offering the flexibility to match the power requirements of the specific solar installation.

Both the fuse holder and fuse work in tandem to ensure optimal performance and protection for your photovoltaic strings, preventing any electrical faults from compromising the entire solar system.
