These SAE plugs would simplify the process of converting reversed polarity.
The sae polarity reversed adapter is SAE to SAE connector, it is compatible with battery tender and the other brand SAE connector wires.
This connect plug would be the easiest way to make the reversed polarity correct for SAE to SAE connector.
The outlet polarity of different brand solar panel chargers maybe different. And the polarity may be reversed when the solar panels connect with the other brand SAE quick connection extension cable,solar charger regulators,and DC power kit
This sae adaptors can be connected with 12V/24V DC systems. Do not use to make connections exceeding 30A(current).
