The manufacturer of our solar controllers has recently upgraded the roof and pool sensors. The sensor connector colours have been changed to make identification easier. Instead of both sensors having a green connector, the roof sensor is now red and the pool sensor is blue.

The roof sensor cable has also been changed. This cable is now specially produced starting from virgin copper plate which is then extruded and tinned. The tinned wire is then covered with a UV stable Poly Propylene outer sheath, one being red and one black. These two cables are then encapsulated in a UV-stable PVC sheath. All this has increased the strength of the cable three fold and is now fully waterproof which means longer life and can lay in water without degradation. The sensors are now potted in a new grade Poly-Urethane which can be identified by its black colour.
