The kit does not include the solar panel, the battery or the evaporator.


  1. Fully automatic including the filling of the header tank
  2. Smart irrigation controller – the irrigation is controlled by the prevailing weather conditions rather than a program
  3. A light sensor provides the option of irrigating at night time only without using a timer
  4. You can adjust the water usage by adjusting the control dripper
  5. The water usage is directly proportional to the net evaporation rate
    a unique feature of measured irrigation
  6. Respond appropriately when there is an unexpected heat wave
  7. When it rains, water enters the evaporator and delays the start of the next irrigation
  8. The water usage is independent of the water supply pressure
    a unique feature of measured irrigation
  9. Uses much less water without affecting the yield
  10. Simple and low tech and so there are fewer things to go wrong
