Background
5 x Irrigation Control Systems located around the City of Salisbury at various parks and sporting grounds could have been an expensive exercise for the City. The costs of cable trenching, power meter installation, ongoing supply charges, and the grid connection fee weighed up against the relatively low amount of electricity required to power the irrigation controllers pointed the city towards Green Frog Systems to design a suitable solar harvesting and energy storage device that would be independant of the power grid.
