DEGSON PV Inverter Connector Solutions
DEGSON PV Inverter Connector Solutions
With decades of specialization in photovoltaic connectors, DEGSON designs a full matrix of DC, AC and communication connectors based on full-scenario application demands of inverters. Supported by independent R&D capabilities, our precise, safe and efficient connection solutions resolve various connection pain points in inverter operation, deliver stable power generation for PV systems, and convert every ray of sunlight into reliable electricity.
I. Address Industry Pain Points, Empower Efficient Inverter Operation via Connection Technology
PV inverters frequently suffer from poor environmental adaptability, high transmission loss, inconvenient maintenance and potential safety hazards in practical use: performance degradation under high temperatures, connection failures caused by coastal salt spray corrosion, heat dissipation and insulation challenges at high altitudes, and fire risks from DC arcing. All these bottlenecks limit inverters from reaching optimal efficiency.
As the "neural network" linking inverters with PV modules and power grids, connection systems directly determine the stability and safety of the entire system.
Centered on Precise Matching, Safe Durability & Easy Efficiency, we develop exclusive connection solutions for PV inverters. Seamless full-link coverage from DC input and AC output to communication control comprehensively eliminates connection troubles, enabling inverters to run stably and efficiently across all complex scenarios.
II. Full-Range Connector Matrix for All Inverter Scenarios
Different types of PV inverters for diverse scenarios have distinct requirements for connection systems. We have built a complete product portfolio covering DC, AC and communication connectors. Every product undergoes rigorous testing, perfectly compatible with single-phase and three-phase PV inverters. Balancing practicality and innovation, we provide customized connection support for PV projects of all scales.
DC Connectors: Secure the Inverter’s Input Barrier for Safe & Efficient Power Transmission
The DC side connection serves as the first energy transmission checkpoint of PV systems, directly governing the input stability and safety of inverters. Centered on the PV-DC series, our three core DC connector lines accurately meet inverter DC input requirements, cut energy loss at source and prevent safety risks.
• Standard PV-DC Connectors
Benchmark products for PV DC connection, fully compliant with IEC 62852:2014 + AMD1:2020. Adopting high-purity tinned copper conductors with contact resistance ≤0.3 mΩ, they minimize conduction loss for maximum power transmission efficiency.
Housings are made of PA insulating material with UL94-V0 flame retardant grade and IP68 protection rating, operating reliably from -40℃ to +85℃. Ideal for both residential and large commercial & industrial inverters, they form a solid safety barrier for DC input.
• PV-DC Fuse-Type Connectors
Specially engineered for DC input safety of inverters with integrated fuse structure to effectively prevent fires triggered by DC arcing. The circuit cuts off rapidly under overload or short-circuit to protect core inverter components.
Interchangeable with standard PV-DC connectors without interface modification. Perfect for projects requiring enhanced safety, especially large-scale PV power stations, delivering dual-layer safety protection.
• PV-DC Quick-Install Connectors
Optimized for mass inverter installation efficiency with tool-free quick-lock design, eliminating complicated crimping and torque tightening procedures to drastically shorten construction cycles and cut labor costs.
Retain all core advantages of the PV-DC series: waterproof, dustproof, wide temperature resistance and anti-corrosion. They perform equally well in harsh outdoor environments, enabling fast assembly without compromising performance and solving efficiency bottlenecks for mass installation in large PV projects.
AC Connectors: Match Multiple Inverter Specifications for Stable Grid-Tied Power Output
The AC side connection is the critical link for inverters to feed converted AC power into the grid, demanding high withstand voltage, sufficient current capacity and strong compatibility from connectors. We offer 3-core, 5-core and 10-core models tailored to single-phase and three-phase inverters, covering all AC output scenarios and ensuring stable grid power transmission.
• 3-Core AC Connectors
Designed for single-phase residential PV inverters; rated at 600V AC with maximum 80A rated current, compatible with 4–16mm² cables. Screw or crimp wiring enables easy disassembly.
IP68 high protection resists heavy rain and condensation outdoors, widely adopted for AC output of residential and small commercial single-phase inverters.
• 5-Core AC Connectors
Developed for three-phase commercial & industrial inverters, suitable for medium-to-large PV projects with outstanding anti-interference performance and electrical stability.
UV-resistant and anti-corrosion housing materials prevent contact failures from long-term outdoor exposure, stabilize three-phase power output and reduce grid connection loss.
• 10-Core AC Connectors
Built for high-power three-phase central inverters with superior current carrying capacity to deliver steady high-power grid connection. Suitable for large ground-mounted PV power stations and other high-end scenarios, offering reliable AC connection support for high-power inverters.
Communication Connectors: Build Intelligent Inverter Links for Precise Monitoring
Against the backdrop of intelligent PV systems, remote data collection and operational monitoring of inverters have become standard demands, with communication connectors acting as core data transmission carriers.
Custom-designed for PV inverter communication, these connectors feature stable interfaces compatible with multiple communication protocols. They transmit real-time operational data including power generation, voltage, current and fault alarms, establishing a stable data channel between inverters and monitoring platforms.
Equipped with anti-electromagnetic interference, anti-loosening and anti-corrosion properties, they maintain uninterrupted signal transmission in complex outdoor environments. Operators can remotely inspect equipment and resolve faults instantly to lower maintenance costs and boost refined digital management of PV systems.
Compatible with single-unit monitoring for small residential systems and centralized monitoring for multi-inverter large power plants, they provide solid hardware support for intelligent inverter O&M.
