1.Applies to the use of three-phase asynchronous motor pump;
2.Mppt, maximum power point tracking algorithm for dynamic vi, fast response speed, good stability, the efficiency of mppt 99%;
3.Fully automatic operation, do not need to set any parameter , and also can according to the actual situation to knob the speed range of pumps
4.Using efficient svpwm algorithm, the main circuit and high reliability, the highest conversion efficiency up to 98% ;
5.Intelligent recognition of input voltage range, without the need to manually adjust the open circuit voltage, maximum power point voltage
6.No button set to run automatically, only a switch control stop and boot;
7.The maximum flow support manually controlled, prevent stop and boot repeatedly when water less or less needs of water
8.The function of protecting the motor complete, can choose the upper and lower water level monitoring and control circuit, to prevent dry or over flow¡®s pumping;
9.Ip52~ip63, use environment temperature: -20 ¡æ ~ +50 ¡æ;
10.Allows a wide range of input voltage, l type 200-450vdc, h type of 460-750v
11.Over-voltage, over-current, over temperature , short-circuit , against lighting protection
12.Dc input anti-reverse function
13.Small size and lower weight
Size: 50*35*27cm
Weight:8.9kg
Dimensions:30*15*10cm
