Noted: We suggest solar panel power should be 1.3-1.4 times higher than solar pump power ,
And solar pump inverter power should be higher level than solar pump.
When solar pump distance to inverter higher than 100m,it should be equipped with Output reactor or higher level power inverter .
For Solar panel,l total VOC less than Maximum DC voltage of inverter and Solar panel vmp is recommend 530V for 380V pump and 305V for 220V pump
1. Dual Supply Mode - Solar DC and Grid AC Compatible
1. Innovation Design with Dual CPU
* It can enter automatically to sleep mode when the intensity of sunlight is weak, as well as can exit the sleep mode when the intensity of sunlight is becoming strong.
* Automatic sleep when on high-water level and automatic restart when on low-water level to realize automatic control through water level.
* Multiple power supply design, power input can be solar energy photovoltaic DC power supply, can also
be single phase or three phase AC power, simple wiring.
* Smart operation, water level detection and operation panel to prevent overflow, dry pumping.
* Protect itself in trouble and improve the reliability of whole system.
1. GPRS (support 2g/3g/4g internet)
It supplies water volume monitoring and operation of inverter from anywhere at anytim
It’s convenient to visit real time and historical data via web or Android APP anytime and anywhere.
This easy-to-use platform makes monitoring of solar pump systems simple and convenient,
far reducing operate time and monitoring costs as well.
2. LCD keypad
Standard inverter are with LED keypad,LCD keypad is optional.
LCD keypad can monitor 4 parameters at the same time. LED keypad show one parameter only.
LCD keypad with detailed parameter explain,no need use user manual ,more user friendly.
LCD keypad with copy and update and download function.widely used for government projects and big farms.
