MC4 Cables

MC4 – MC4

— "Solar" DC extension cables: standard MC4 (male/female) connectors on both ends with locks that allow you to securely connect panels together or reach from the panel to the controller/portable station. This cable is made from UV and frost-resistant PV wire (usually 4–6 mm²) with low resistance and protection rating up to IP67, designed for high DC voltages (typically up to 1000 – 1500 V, check actual values in the datasheet). It is used only on the DC side and is not intended for 230 V AC; during assembly, it is important to observe the polarity, input current/voltage of the station, and the track length to avoid voltage drop. Compared to MC4–XT60/Anderson, this MC4–MC4 cable is specifically for "panel↔panel/extension," while connection to EcoFlow/Bluetti/Jackery is made through the corresponding adapter to their input. Example: connect two 100 W panels in series and output them via a MC4–MC4 extension to a portable station at a campsite.
