  • 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 98%.
  • 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 (DC 260~350V, DC 450~750V), 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.
  • The bypass- AC source which runs automatically when the sun is Not sufficient or absent.

solar pump inverter wiring application

Tips: Role of MPPT
MPPT, short for Maximum Power Point Tracking, means that the inverter adjusts the output power of the PV array according to different ambient temperature and illumination intensity, so that the solar array always outputs the maximum power.
Since the solar cell is subject to the influence of external factors, including light intensity and environment, the output power is ever-changing. The solar pump inverter with the MPPT is to make full use of solar array, ensuring them to operate at the MPP. In other words, when the solar radiation remains unchanged, the output power after the introduction of MPPT is higher than that before the introduction of MPPT.

This solar water pump inverter has saved me money
The 15kW solar water pump inverter is very user-friendly and the LCD display provides real-time monitoring of the system's performance. I love the fact that it automatically adjusts the pump speed according to the available sunlight, which saves me a lot of energy and money.

Smart solar water pump inverter
The solar water pump inverter purchased by my family is too smart to realize automatic water level control, sleep automatically when the water level is high, and restart when the water level is low. With intelligent operating system, water level detection and operation panel can prevent overflow or dry pumping. This way, you will not be afraid of overflowing or running out of water when you travel.
