On October 20, 2022, Shenzhen Solartech Renewable Energy Co., Ltd.(Solartech) successfully held a global  "PB-G4 Smart Pro E Solar Pumping Inverter" new product online launch conference.  
At the meeting, Mr. Chen Ruijian, deputy general manager of Solartech, announced the official launch of the PB-G4 solar water pumping inverter, and introduced the advanced technologies and advanced features of the PB-G4 water pumping inverter , in order to promote the global development of the solar water conservancy industry.
Like the series of solar water pumping inverters launched by Solartech in the early stage, the PB-G4 series solar pump inverter continues the design standards of high quality and high efficiency, and at the same time strengthens its environmental adaptability, power supply adaptability and motor adaptability in the inverter performance. In the actual solar water pump system project, it can help simplify system design, wiring and installation, improve system safety and reliability, and also save the overall cost of system installation and ensure the service life of equipment. What is more, PB-G4 solar pumping inverter have extended function of auxiliary surplus energy storage and surplus power grid connection with solar charging controller and solar grid-tied inverter equipped.

 
The conference was attended by technical experts, distributors and user representatives from solar water conservancy, solar water-saving irrigation, solar modules, solar water pumping, solar water pumps and water treatment. The technical & support department director of Solartech introduced the product functions and system technology of PB-G4 solar water pumping inverter, and the overseas business director of Solartech combined with actual cases to discuss with attendees how solar water pumping system solutions and solar water conservancy industry integrated solutions play a role and contribute to solve global water crisis, food shortage, energy security and ecosystems.
 
PB-G4 series solar pumping inverter is the fourth generation of intelligent professional-grade solar water pumping inverter. The characteristics are as follows:
