With this Zappi install we were able to bring the power supply directly through the back of the unit and hide the wiring completely.  It was made a little tricky as the drainpipe was exactly where the customer wanted their charger, but we managed to move it across and they were very pleased with the result. Plus now their daily commute can be powered entirely with sunshine as their solar panels are connected to the Zappi, which is good news for everyone.
