ADVANTAGES OF DC (AC/DC) SOLAR PUMP 1.Permanent magnet DC brushless synchronous motor: The efficiency is improved by 15%-20%; 2.304 S/S pump shaft. 3.Brass or stainless steel outlet/connector/ oil cylinder. 4.Japanese NSK bearing: prolong the working life. 5. Double bearing motor base: can work under more axial pressure 6. Alloy mechanical seal: Longer working life and high reliability. 7.Motor coil is made by automatic winding machine with centralized winding technology, motor efficiency is much improved. 8.Intelligent water shortage protection: The pump stops working automatically when there is no water in the well,and automatically start working 30 minutes later. 9.Controller: (1 )Waterproof grade: IP65 (2)Ambient temperature: -15*C~60°C (3)MPPT function, the solar power utilization rate is higher. (4)Automatic charging function: Guarantee the pump normally working, meanwhile charge the battery;And when there is no sunshine, the battery can make the pump continuously working. (5)LED displays the power, voltage, current, speed etc working condition. (6)Frequency conversion function: It can automatically run with frequency conversion (7)Automatically start and stop working. (8)Water proof and leak proof: Double seal effect. (9)Soft start: No impulse current, protect the pump motor. (10)High voltage/Low voltage/Over-current/High temperature protection
