Agricultural Irrigation 220Volt Single Phase Solar Pump Inverter 99% Efficiency

Solar water pump controller inverter 11kw 15kw for solar pump system

MPPT introduction

MPPT means Maximum Power Point Tracking; it’s a special function for solar system, which is used to get the

maximum possible power from one or more photovoltaic devices, typically solar panels. Solar panels have a

complex relationship between solar irradiation, temperature and total resistance that produces a nonlinear output

efficiency which can be analyzed based on the I-V curve. It is the purpose of the MPPT system to sample the output

of the cells and apply the proper resistance (load) to obtain maximum power for any given environmental conditions.

By adopting this technology in the solar pump inverter, it increases the working efficiency of solar panels,

and also adjusts the output frequency of solar pump VFD based on the sunshine strength; make sure the system

always works at an optimum condition.

Electrical Specifications and Power degree

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,total VOC less than Maximum DC voltage of inverter and Solar panel vmp is recommend

530V for 380V pump and 305V for 220V pump.

VEIKONG VFD500-PV solar pump inverter Features:

Product Application

 

 

Quality Control

VEIKONG solar pump VFDs have passed comprehensive test process during manufacturing.

 

R&D test: test the hardware and software performance, to make the design more optimization, makes sure the products have excellent

performance before production;

 

Board test: test the performance of every board in our products, to reduce product defective rate;

IQC: take strict quality inspection for every income components, to ensure every income components are qualified.

 

Aging test: make the solar pump VFDs at run status, put them in the aging test house at 50°C for 48 hours, to remove every unqualified products.

 

Load test: the last and the most important test, add different load to the solar pump VFDs, test their input and output value, to check their

working performance. unqualified products will be removed from the team.

By applying such strict testing process, VEIKONG ensures every outgoing solar pump VFD has excellent quality.
