Project Description



The SmartLine Solar irrigation control system features the industry’s first hybrid solar to AC power supply, allowing the SmartLine weather based irrigation control system to operate in locations with no power. SmartLine Solar uses proven SmartLine controllers and industry standard 24VAC valves for greatly enhanced operational life and reduced equipment cost.



  • Converts SmartLine to a totally “portable” water management system by using proven solar technology
  • SmartLine is a SWAT tested ET system
  • Green power source using 100% renewable energy
  • Easy installation for both Conventional and 2-Wire systems
  • SmartLine Solar uses industry standard 24VAC valves, which out perform debris-prone latching solenoids required with battery operated systems
  • System Diagnostics include Volt meter, Amp meter and Valve Locator
  • 2-Wire SmartWire compatible
  • LCD display indicates battery and solar power condition
  • Dual deep cycle batteries provide up to 7 days of operation with no solar charge
  • State of the art Solar Charge Technology (SCT) prolongs battery life and protects batteries from over charge and assures a full charge
  • Using standard AC power components makes for easy conversion from solar to grid power and allows early stage construction of landscape in new construction projects


  • 4 programs: A, B, C; program D can operate concurrently
  • 8 start times per program
  • Indoor/Outdoor Rated
  • Zone run times settable from 1 min. to 9 hrs. 55 min.
  • Rain/Freeze sensing on/off button with Tri-Color LED indicator

  • SLW5 Weather Sensor rain delay programmable from 0 – 99 hours
  • Seasonal % adjust by program, by month
  • Omit time of day window, day(s) of week, and up to 7 calendar dates
  • Programmable zone-to-zone delay 1 min. – 3 hrs.
  • Watering days: custom days of the week, odd/even, or interval days
  • Run/Soak cycles by program
  • Large backlit LCD display
  • Non-volatile memory – with no battery required
  • Internal 120VAC/230VAC transformer with pre-installed 6’ line cord
  • 2 Watering modes: Basic Mode and Smart Mode

  • Accumulates total run times by zone from the last reset date
  • Clear deficits for all zones
  • Extended rain delay programmable from 0 – 99 hours


  • Manual test runs each zone with zone run times from 10 sec. – 10 min.
  • Manual zone operation of a single zone (1 min. to 9 hrs. 55 min.)
  • Push button manual start of a program from control panel
  • Fault review displays all faults, including open and shorted zones
  • Test function using on-board multi-meter
  • Built-in valve locator
  • Backtrack Stored Program™


  • Zone-to-zone delay
  • Master valve timing sequence with zone valve programmable
  • Master valve/pump start operation assignable On/Off by zone
  • Clear program function
