1、Product Overview（Update Connector Type）

This DC 5521 Y-splitter cable is designed for solar panel systems, featuring a 2 Male to 1 Female (2 Male Plugs, 1 Female Jack) design. Its core function is to parallel connect 2 solar panels to 1 controller/power supply. For more panels, you can connect multiple Y-splitters in series (e.g., 2 cables for 4 panels, 3 cables for 6 panels). With 22AWG pure copper core and DC 5521 interface (5.5x2.1mm), it’s compatible with 90% of solar panels and controllers on the market, making it a must-have for home/outdoor solar system expansion.

3、Product Advantages（Emphasize 5521 Compatibility）

【Industry-Standard 5521 Interface】

DC 5521 (5.5x2.1mm) is the most common interface for solar panels, controllers, and portable power banks. Our store’s SEP-SP series solar panels (e.g., SP50) use 5521 Female connectors, and most controllers (PWM/MPPT) use 5521 Male connectors. This cable’s 2 Male to 1 Female design perfectly matches this standard—plug-and-play, no adapters needed.

【2 Male to 1 Female, Perfect for Parallel Connection】

Designed for the common scenario of "2 solar panels to 1 controller":

2 Male Plugs → Connect to 2 solar panels’ 5521 Female jacks;

1 Female Jack → Connect to the controller’s 5521 Male plug; No more confusion about "which end goes where"—installation is a breeze.

【22AWG Pure Copper, High Efficiency】

22AWG pure copper core (0.32mm2) has a low resistance of 0.05Ω/m, ensuring 98% transmission efficiency. Even with 2x300W solar panels (600W total), there’s no significant power loss.

【Heat Resistant & Safe】

PVC outer sheath resists 80℃ high temperatures (no softening in summer sun) and 300V voltage (far exceeding solar panel’s 12-24V output). It’s flame-retardant and绝缘, preventing short circuits and electric shocks.

【Expandable, Support Multiple Panels】

To connect 4 solar panels, simply plug the second Y-splitter’s Female Jack into one of the first Y-splitter’s Male Plugs (ensure all panels have the same polarity). This design supports up to 8 panels (depending on controller power).
