Reliable Overvoltage and Surge ProtectionThis PV combiner box integrates advanced surge protection devices (SPD) and overvoltage safeguards, offering robust protection against electrical anomalies. Each string is secured with its own 15A fuse and circuit breaker, minimizing the risk of equipment damage and ensuring a safer solar PV system operation.
Flexible and User-Friendly InstallationWith selectable ports (2, 4, or 6), customizable cable lengths, and direct terminal block wiring, this box adapts easily to varying solar projects. Compatible with MC4 connectors and featuring multiple mounting options (wall or pole), installation is straightforward and versatile for different outdoor scenarios.
Built to Last in Outdoor EnvironmentsAn IP65, fire-resistant, and UV-protected enclosure shields components from dust, rain, and sun. Constructed from flame-retardant polycarbonate, it meets IEC 60529 and CE standards, ensuring durability and reliability even under harsh environmental conditions. Minimal maintenance is required, making it ideal for long-term solar infrastructure.
FAQs of Overvoltage 2 to 6 Ports Small PV Combiner Box:
Q: How do I select the appropriate number of inputs for my PV combiner box?
A: Choose between 2, 4, or 6 input ports based on how many separate solar panel strings you plan to connect. The design allows easy scalability for expanding or adapting your solar system.
Q: What benefits does the installed surge protection device provide?
A: The surge protection device (SPD) defends your solar system against voltage spikes caused by lightning or grid fluctuations, protecting sensitive components and ensuring uninterrupted power flow.
Q: Where can I install this PV combiner box for optimal performance?
A: The combiner box is designed for outdoor use, thanks to its IP65 weatherproof and UV-resistant enclosure. It can be mounted on walls or poles, providing flexibility in placement near your solar arrays.
Q: What is the process for connecting solar panel strings to the box?
A: Connect each string using the MC4-compatible terminals and direct terminal blocks. Each input is fused, and the integrated circuit breakers offer manual or automatic disconnection for safety and maintenance.
Q: When should routine maintenance be performed on the combiner box?
A: Minimal maintenance is required, but periodic inspections (twice a year) are recommended to check for secure connections and proper operation of fuses and circuit breakers.
Q: What standards and certifications does this combiner box meet?
A: The box is manufactured to comply with IEC 60529 for ingress protection and is CE certified, assuring safety and reliability for electrical installations.
