Solar PV Connectors
From standard MC4 string wiring to T/Y branch combiners, anti-arc safety connectors and IP68-rated waterproof solutions — copper-contact PV connectors built for 1000 V and 1500 V DC systems. OEM / ODM from prototype to volume.
Product Series
Five connector families to cover every node in a photovoltaic system — from module to inverter, string to combiner box.
MC4 Connector
The global standard for solar string wiring. Snap-lock mechanism, UV-stabilised housing and tinned copper insert — fully MC4-compatible, tool-release safe.
T-Branch Connector
Three-way splitter for parallel string combining. Routes two input strings to one output, eliminating junction boxes in small-scale arrays.
Y-Branch Connector
1-to-2 (or 1-to-4) splitter for distributing a single main cable to multiple parallel strings. Commonly used at the inverter input side.
Anti-Arc Connector
Arc-quenching structure suppresses DC arc within <10 ms when disconnecting live circuits — mandatory for 1500 V high-voltage utility plants and NEC 2023-compliant installations.
IP68 Waterproof Connector
Submersion-rated for floating solar, coastal installations and high-humidity tropical climates. Double-sealed housing with stainless steel locking ring.
Custom Specification
Non-standard voltage, higher current ratings, custom housing colours, laser-marked logos, pre-assembled cable lengths — send us your drawing.
