Solar cable to link MPPT to battery

[Frazman]

I have a surplus of solar cable left over from when I fitted my panel a while back.
I’m now in the process of installing a separate solar charge controller and making the ctek solar charger redundant (due to solar panel being too big VoC).

Is there any issue using solar cable to link the solar charge cable to the battery? I know it’s not the most flexible, but appears suitable for the voltage and current it will carry.

thanks

That will depend if the cable is rated ok to carry the current ?
Remember the solar panels will output a higher voltage then the charge controller will bring it down to battery voltage, as voltage drops current increases so the cable from controller to battery will almost certainly carry a higher current than the cable from the panel to controller
