Solar Pump Inverter – Variable Frequency Drive (VFD) | Part Two

Solar pump inverter is used to control and regulate the operation of solar water pump system (PV pumping system). It can convert the DC from the solar array into AC to drive the water pump.

How to Identify a High-Quality Solar Pump Inverter?

The basic design criteria for the solar pump inverters include rated voltage, capacity, efficiency, maximum power point tracking (MPPT) effectiveness, communication characteristics, and safety. These aspects are also important assessment factors to identify the performance of a solar pump inverter.

• A PV pump inverter should have a reasonable circuit structure and strict screening of the components used. The pumping inverter has various protection functions, for example, input DC polarity reversal protection, AC output short circuit protection, overheat and overload protection, etc.
• It should have a wide range of DC input voltage adaptation. As the solar insolation intensity will change, to ensure that the pump can work normally, the solar pump inverter needs to ensure that the AC output voltage is stable within the voltage range required by the load.
• It should have high efficiency, mainly referring to high conversion efficiency.
• A solar power inverter has high reliability, as a solar water pumping system is mainly used in remote areas. Many systems are even unattended and maintained, so they need high reliability. 

Where to Find a High-Effective Solar Pump Inverter?

Now, you know that the solar water pump system with solar water pump inverter is more efficient, energy saving, space saving and environmentally friendly than the traditional one. So, where can you buy an efficient solar water pump inverter for your system? Who is a trusted supplier?

TrueWay Tec has selected several cost-effective manufacturers from hundreds of factories in China to provide you with customized and high-quality services. Buying the best quality products at the most suitable price is our aim.

Based on the design concept of environmental protection and economy, the solar water pumping system adopts water storage instead of electricity storage, and has no battery device. It makes the entire solar water pump system more reliable, while greatly reducing construction and maintenance costs.

The solar water pump inverter adopts advanced MPPT technology, which has faster corresponding speed and better operation stability. More importantly, the power generation efficiency of the solar cell array can be fully utilized.
In this way, the water pump can realize automatic control of water level. The pump stops automatically when the tank is high; otherwise, it restarts automatically. The same applies to different intensities of sunlight at different times of the day.

It has a variety of protection functions to improve system reliability. Specially designed for water users, suitable for various occasions, easy to operate.
