Product: 10M_12 AWG4MM2 Red Cable Overview This 10M 12 AWG 4MM2 red solar extension cable is designed to extend connections in PV systems while minimizing power loss. The cable diameter and gauge provide stable current delivery and improved transmission speed for short to medium length runs. Key benefits Stable power delivery: 12 AWG 4MM2 gauge reduces resistance compared to smaller wires, helping maintain consistent current to connected equipment. Reduced power loss: Optimized conductor size and low resistance characteristics reduce voltage drop over the 10 meter run, improving overall system conversion efficiency. Clear polarity and easy identification: Red color simplifies positive line identification during installation and maintenance. Flexible routing and installation: 10 meter length gives freedom to position panels, controllers, and inverters without relying on multiple splices. Reliable performance: Designed for continuous electrical transfer in solar applications where steady current and minimal losses matter. Important attributes Size and gauge: 10M_12 AWG4MM2 specifies 10 meter length with 12 AWG, equal to 4MM2 cross sectional area, suitable for many residential and small commercial solar connections. Color: Red cable for positive line identification. Function: Solar extension cable for transferring DC power between panels, charge controllers, inverters, and batteries. Compatibility: Suitable for use with solar panels, MPPT and PWM charge controllers, inverters, battery banks, and DC loads that accept 12 AWG or 4MM2 wiring. Practical applications Rooftop panel to charge controller: Extend the positive run from roofmounted panels down to the charge controller or combiner box without significant voltage loss. Portable and RV solar setups: Provide a neat, identifiable positive lead when configuring portable panels or RV roof arrays where routing distance varies. Off grid inverter or battery connections: Use as the positive supply line between panels and battery systems or between combiner outputs and inverters in small off grid installations. Installation tips Verify system current and acceptable voltage drop for your run length before final installation. Keep connections tight and weather protected at junctions and terminals. Match cable selection for negative line to maintain balanced resistance. This product provides a straightforward way to extend DC solar wiring with a clearly identified positive conductor and a gauge chosen to reduce losses over a 10 meter span.
