What\'s the difference between 2.5W Solar Pump with other Pumps. 1. The 1.5W or 1.4W will stop working immediately when the solar panel partial covered or in cloudy day 2. But the 2.5W can still work when partial covered, and in cloudy day thanks to the new IC sensor and storage battery.
WARM NOTICE: 1. The pump will NOT WORK AT NIGHT or IN DARK Environment, because if the IC sensor can not detect any sunlight, it will stop working automatically to protect the motor and circuit to aviod draining the battery. 2. When NO WATER DETECTED within 15s under sunlight, the solar pump will stop working automatically, it sprays water till 6PM in the afternoon (when the sunlight is very weak) then power off automatically and keep certain battery power for next day use. 3. If the pump stops working during use, please check if it has enough water, or the pump inlet is blocked by dirts, please clean it in time, and cover the solar panel completely in a dark environment, then reactivate the product. Put it back into the water to work properly.
