The LEIT-2 is solar powered wireless irrigation controller powered by a photovoltaic module, which harnesses ambient light energy to generate and store electricity to power the controller. No AC power is needed or batteries used. Unlike other conventional solar panels the LEIT-2 is environmentally friendly in that it is certified lead free and uses light as its power source. The LEIT-2 utilizes a patented technology enabling a smaller and much more efficient photovoltaic cell to be inside a small package without a backup battery. This allows the unit to be ultra-compact and to be mounted directly onto the cover of valve boxes. This feature eliminates the need for long wire runs offering quick and simple installation. The controller is operating using our DC valves only model 305DC-XXX and has a mounting option such as clipping the controller to the valve or directly onto a valve box. The result is an advanced, two-way communication device that offers features over and above standard irrigation controllers.
