Product Description
1. Powerful practicality and wide applicability
2. Easy to install and low cost
3. TUV and UL certified to meet high customer requirements for photovoltaic connectors
The QC4.3 connector, with its outstanding practicality and wide applicability, has become the preferred product in the fields such as photovoltaic inverters, photovoltaic combiner boxes, and micro-inverters. It is divided into regular models and anti-stupid models. Among them, the QC4.3 foolproof connector relies on its unique anti-stupid design to effectively avoid the risks of misinsertion and wrong insertion, providing a solid safety guarantee for the connection of equipment. At the same time, the connector shows a diverse feature in the design of the external structure, fully meeting the personalized needs of different customers.
This connector has strong compatibility to ensure that various devices can achieve seamless connection. In addition, the application of high-quality materials makes the connector have excellent durability and stability. Even in the case of long-term operation, it can still maintain stable performance, greatly reducing maintenance costs. The QC4.3 foolproof connector also has efficient current transmission capacity and extremely low contact loss, thus achieving the maximum utilization of energy and enhancing the overall efficiency.
Under harsh environmental conditions, the QC4.3 connector also performs exceptionally well. Its IP67 level of waterproof ability allows the connector to operate stably in environments such as humidity and heavy rain, providing a strong guarantee for the safe operation of the photovoltaic system. Whether in extreme environments such as high temperature, high humidity, or severe cold, it can maintain stable performance to ensure the continuous and stable operation of the photovoltaic system.
QC Solar（301278）always upholds the spirit of innovation, continuously pursues excellent quality, and is committed to providing customers with the best quality products and services. We firmly believe that every reliable connection is a strong support for the efficient use of energy. Let us go hand in hand and jointly promote the prosperous development of the photovoltaic industry.
Technical Data
(1) Color distinction: The color of the connector body at both the photovoltaic panel end and the wire end is gray; both the connector at the energy storage panel end and the wire end are blue; the connection scenario of the connector can be distinguished from the appearance.
(2) Foolproof design: The connectors in the two scenarios have a foolproof design at the insertion point, and the gray and blue connectors cannot be plugged together.
