Review on 🔌 High-Quality CERRXIAN 50cm 10AWG SAE to Male & Female Adapter Cable – Perfect for RV Panel Solar Systems by Nick Atkinson

Good product. However, the polarity (red +, black -) does not match the polarity of the connector on my Renogy panel. I don't know if there is a standard for this. In any case, the supplied plug for polarity reversal was practical. The only problem that remains is that the red wire is negative, not positive, and you should always keep that in mind. Bottom Line: Always have a voltmeter handy when using any solar product to check the polarity of your connections.
