Specification: Shell material: ABS Solar panel production process: Glass lamination Solar panel power: 18V 10W Solar panel working current: 555mA Solar panel size: 350 x 235 x 15mm / 13.77 x 9.25 x 0.59in 22 red + black wrapped wire length: 5m / 16.4ft Battery: 11.1V 2200mAh lithium battery lithium battery Overcharge protection voltage: 12.75V Overdischarge protection voltage: 8.1V Working temperature (charging): -10 ℃ - 45 ℃ Storage temperature (discharge): -10 ℃ - 45 ℃ Internal resistance: Less than 120m Ω Weight: 138g / 4.86oz Service life: 500 cycles Water pump: Brushed DC water pump Water pump power: 5W Working voltage: DC 12V Flow rate: 500-1200Ml/Min Load current: 0.5A Working environment temperature: -10 - 45 ° C Product size: 166 x 114 x 47mm / 6.53 x 4.48 x 1.85in Product weight: 1.7kg / 3.74lb Host button description: 1. ON/OFF key: main switch, 2. Watering Time key: working time setting, 3. Interval Time key: interval time setting Shutdown current: Less than 500uA Working current: 500mA 030 water pipe length: 10m / 32.8ft (black PVC, inner diameter 3mm, outer diameter 5mm) 085 water pipe length: 5m / 16.4ft (black PE, inner diameter 8mm, outer diameter 10mm) Drop arrows: 50pcs (Blue, 7-shaped drop arrows 100 x 50mm / 3.94 x 1.97in) Product color: Dark Green Waterproof grade(host): IP65 Solar charging time: about 4-5 hours Control mode: Switch Timing watering: 1-30min Timing: 3H, 6H, 12H, 1d, 2d, 3d, 7d Description: Working time range: 30 gears Watering Time ranges 01, 02, 03... 29, 30 cycles (working 01 for 1 minute, working 02 for 2 minutes, and so on. When the current working time reaches, the motor will stop, it enters the interval range.) Interval time range: 7 gears Cycle 3H, 6H, 12H, 1d, 2d, 3d, 7d (3H is 3 hours, 6H is 6 hours, 1d is 24 hours, 2d is 48 hours until timing, and so on. When the current interval time reaches, the motor will stop, it enters the working range.) Water level detection: Water shortage: The buzzer sounds twice in 1 minute to indicate a water shortage, and E1 flashes slowly (sounds twice in 1 minute until there is normal water, and then turns off the buzzer and alarm E1 code disappears). The buzzer does not alarm at night, only displays LED digital display, and E1 flashes slowly. Motor protection (idle and locked): Idle: The digital tube E2 slowly flashes, and the buzzer sounds twice in 1 minute. (The buzzer does not sound at night, only the digital display and E2 flashes slowly) Battery discharge and charging protection: Discharge: When the battery is below 10V, the digital tube will flash quickly and the water pump will be turned off. Restart the power condition and charge the battery to 10.6V or above during the day before starting the water pump. Charging: When the battery is charged to 12.45V or above, disconnect the charging to protect the battery. During the day, when the battery is below 12V, continue charging to supplement work. The buzzer only prompts during the day and does not work at night. Packing List: 1 x Solar Panel 1 x Controller 1 x Bracket 1set x 5m / 16.4ft Main Water Pipe 5 x 10m / 32.
