1)The efficiency is improved by 15%-20% because of multi-stage impeller
2)Save energy by reducing the consumption of solar panels
●Two designs for selestion: The material is made of stainless steel or copper for selection ●Japanese NSK bearing: Effectively improve wear resistance and corrosion resistance ●Alloy mechanical seal: Using one-piece chassis,the pump is well sealed as well as avoids water heater ●Full copper core motor : Instead of aluminum cable core,the motor with copper core extends the motor's life ●Winding technology:Motor coil is made by automatic winding machine with centralized winding technology, with high mechanization and high production efficiency. ●No dry burning: Intelligent water shortage and full water protection. ●DC Controller:
1) Waterproof grade: IP65.
2) Ambient temperature: -15℃ to 60℃.
3) MPPT function: Maximum Power Point Tracking can .
4) Automatic charging function: When there is no sunshine, the battery can make the pump continuously working
5) Clear visual: LED displays the power, voltage, current, speed etc working condition and error code.
6) Frequency conversion function: It can automatically run with frequency conversion and user also can change the speed of pump manually.
7) Soft start: No impulse current, protect the pump motor.
8) High voltage/Low voltage/Over-current/High temperature protection. 9) Easy installation:It is also easy to install and maintain, with no complicated wiring or plumbing required.
