3 Phase MPPT 99% Solar Pump Inverter chinese manufacturer high
performance
VEIKONG is solar pump inverter, industrial vfd, soft starter
manufacturer.
Product Details and Features:
Features
* Solar pump inverter adopts advanced MPPT control technology,
real-time detection of solar panels power voltage, tracking the
highest voltage and current, efficiency is as high as 99%.
* 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.

Technical Questions and solutions
1. How to achieve Automatic start after stop?
If it is controlled by keyboard no need to set any parameter. If
you want to control by external switch
As the default control mode is keypad control, First set P00.06=1
and use a wire or switch to connect com and DI1,When the switch is
closed, the drive run, when the switch is open, the drive stop
2. How to use a float in the water tank to stop the pump if the tank
is full?
If your float signal is digital signal Use float switch to short DI
1 and com and P00.06=1
3. How to design solar PV water pump system?
Key point: the rated VOC and VMP and power of the PV Array need to
match the input range of the inverter. If needed, we will provide
technical support online.
