With the rapid development of the national economy, the shortage of energy and the pollution of the environment have become the most important problems to be solved in today's society. As a kind of the cleanest, safe and reliable energy, solar energy has become a long-term research topic in various countries because of how it is fully utilized.


The problem of livestock husbandry and drinking water in remote areas is a problem because of geographical constraints. With the country's attention and promotion of photovoltaic applications, solar photovoltaic pumps have been widely used in mountainous villages for water supply, drinking water for people and livestock in desert villages, agricultural irrigation, pasture husbandry, desert management, domestic water and landscape fountains. In underdeveloped areas, drinking water can be guaranteed by solar pumps. Because of its suitability for a variety of terrain, easy maintenance, no need to watch on the characteristics of the favor.

V&T program

V&T RS-P series controller is suitable for photovoltaic, single-phase 220V, three-phase 380V drive three-phase asynchronous motor pump, used in centrifugal pumps, submersible pumps, deep well pumps, sewage pumps, reciprocating pumps, screw pumps. Its energy is an inexhaustible source of clean and environmentally friendly solar energy, as well as an emergency backup diesel generator and grid.


System composition

System consists of solar cells, generators or power grids, V&T RS-P series controllers and three-phase asynchronous motor pumps and other components. Based on the controller's own automatic solar maximum power point dynamic tracking technology, it achieves uninterrupted operation under complicated weather conditions during daytime, saves battery energy and saves a lot of costs, and can be driven by a diesel generator or mains at night. V&T RS-P series controller can directly drive all kinds of applications of three-phase asynchronous motor, high functionality integration, reduce component parts, improve system reliability.
