AQMC4 CONNECTOR INDUSTRY DEVELOPMENT AND HISTORY:

Before 1996, photovoltaic cables were connected using screw terminals or splice connections. With the increase in the number of photovoltaic systems installed, the demand for fast, safe and easy-to-operate connection solutions is increasing.

Because photovoltaic systems are exposed to wind, rain, hot sun, and extreme temperature changes for long periods of time, connectors must be able to adapt to these harsh environments. They must not only be waterproof, high temperature and UV resistant, but also touch protected, high current-carrying capacity and efficient. At the same time, low contact resistance is also an important consideration. All of this must also run through the entire PV system life cycle, at least 20 years.

In 2002, the birth of MC4 redefines the photovoltaic connector again, it truly realizes "plug and play". Rigid plastic (PC/PA) is used for insulation and is designed to be easier to assemble and install in the field。and the more convenient high-strength flame-retardant PPO material makes MC4 more widely used in various installation places

With the rapid development of distributed photovoltaic market, especially household photovoltaic market, the quality problem of the system is becoming more and more prominent. The fire of photovoltaic system not only has a negative impact on the industry, but also involves life safety. According to the investigation report, the mutual insertion of connectors and the non-standard installation of connectors ranked first and third in the cause of fire. AOYWELL photovoltaic connector. It can well solve the crimping problem between cable and connector metal core.
