Product Description

MC4 Solar Y Branch Connector 1 to 2 Splitter Cable Waterproof Flame Retardant 
The MC4 Solar Y Branch Connector (1-to-2 Splitter Cable) is a high-efficiency photovoltaic (PV) combiner designed for parallel connections in solar panel arrays. Featuring IP67-rated waterproof MC4 connectors and flame-retardant housing (UL94V-0), this Y-splitter enables safe, reliable DC power distribution while resisting harsh weather conditions (-40°C to +90°C). Pre-assembled with UV-resistant 10AWG/6mm² cable (optional lengths), it ensures minimal voltage drop when connecting multiple solar panels to a single inverter input.

Features:

Robust Construction	Corrosion-resistant metal contacts with gold-plated terminals (≤5mΩ resistance)
	Double-insulated POE jacket (1000V DC, 30A max rating)
MC4 Connectors	IP68-rated waterproof connectors ensure dustproof and waterproof performance.
Flexible & Durable	Fine-stranded copper allows easy bending and long-term durability.
Low Power Loss	Optimized wire thickness (2.5mm²/4mm²/6mm²) reduces voltage drop over long distances.
Safety Certified	Complies with TUV, IEC 62930, and RoHS standards for fire resistance and environmental safety.
Multiple Lengths Available	Customizable from 0.5m to 10m+ (standard: 1m, 2m, 2.5m, 5m).

Application:

Parallel Panel Connections - Combine 2x solar panels into one inverter input

Battery Bank Expansion - Split charge controller output to multiple batteries

Off-Grid Systems - Optimize small-scale PV arrays (balcony/RV/marine)

Drone Charging Stations - Weatherproof power distribution for outdoor setups
