1、Product Overview

This DC5521 solar panel extension cable is designed for extending the connection between solar panels and controllers/batteries. With a 2M (78.7inch) length, it solves the problem of "short cables" in most scenarios (RV, balcony, camping). Made of 22AWG pure copper and environmentally friendly PVC, it features high transmission efficiency, heat resistance, and durability. Compatible with 90% of solar panels (DC5521 female) and controllers (DC5521 male), it’s a must-have accessory for solar systems.

3.Product Advantages

【2M Perfect Length for Most Scenarios】

*RV: Connects roof solar panels to in-car controllers (2M covers the distance);

*Balcony: Connects window solar panels to indoor controllers (2M won’t cause clutter);

*Camping: Connects outdoor solar panels to in-tent controllers (2M is easy to move). Avoids the embarrassment of "too short" and the mess of "too long".

【22AWG Pure Copper, Low Loss】

22AWG pure copper core (0.32mm2) has a low resistance of 0.05Ω/m, ensuring 98% transmission efficiency. Power loss is less than 2% at 2M, keeping solar power stable.

【DC5521 Universal Connector, Plug & Play】

DC5521 is the standard connector for solar panels/controllers (our SEP-SP series solar panels use DC5521 female, controllers use DC5521 male). The extension cable’s male (center pin +) connects to solar panels, female (center socket +) connects to controllers—no adapters needed.

【Heat Resistant & Durable】

PVC jacket resists 80℃ high temperatures (no softening in summer sun) and 300V voltage (far exceeding solar panel output). It’s also scratch-resistant, withstanding outdoor wear and tear.

【Certified & Reliable】

CE and ROHS certified, compliant with international standards. Safe for home and outdoor use.

4.Applicable Scenarios

*RV Solar Systems: Connect roof solar panels to in-car controllers;

*Balcony Photovoltaic Panels: Connect window solar panels to indoor controllers/batteries;

*Outdoor Camping: Connect tent-side solar panels to in-tent controllers/phones;

*Small PV Plants: Connect PV panels to combiner boxes.

5、Installation Steps

*Identify Connectors: Solar panels have DC5521 female (center socket +), controllers have DC5521 male (center pin +);

*Connect Extension Cable: Insert the cable’s male (center pin +) into the solar panel’s female, and the female (center socket +) into the controller’s male;

*Check Connection: Ensure the connectors are tight—controller should display solar panel status.

6.Notes

*Polarity Check: Male (center pin +) to solar panel female (center socket +); Female (center socket +) to controller male (center pin +);

*Avoid squeeze: Do not place the cable under heavy objects or wheels;

*Regular Inspection: Check for scratches/aging every 3 months—replace if damaged.
