In a photovoltaic power station, to gather the power of a large number of components together and enter the inverter, it must rely on cables and connectors. The photovoltaic connector is one of the components, combiner boxes, controllers, and inverters in the photovoltaic power generation system.

How to ensure the quality and safety of photovoltaic connector parts under the general trend? In recent years, with the rapid development of the photovoltaic industry, how to increase power generation and reduce power generation costs on the premise of ensuring long-term stable and safe operation has become a difficult problem for the photovoltaic industry. The photovoltaic industry is constantly developing, and photovoltaic technology and photovoltaic products are also advancing with the times, constantly adapting to the requirements of the development of the entire market. But no matter how it changes, quality will be our common goal.

With the advancement of battery technology and module packaging technology, the power of photovoltaic modules has become higher and higher, 400Wp+ modules are in the ascendant, and 500Wp modules have entered the market. The internal logic behind this is still the industry's pursuit of low cost of electricity (LCOE), which is used to compare the cost of photovoltaic power generation with other forms of power generation (especially thermal power), and determines the long-term profitability of a power station. High-power components can reduce the cost of BOS (system balancing components), which in turn promotes the decline of LCOE, and has a broad application space in the coming era of parity Internet access. Photovoltaic connector is a kind of auxiliary material of photovoltaic module, and it is the key component of DC side connection of power station. From the perspective of the connector, how do you view the impact of component power increase on power station owners?

2. Failure analysis of resistance Rcr　　The crimping resistance Rcr is mainly related to the crimping quality and the crimping process. We can judge the quality of crimping by the compression ratio and crimping profile. Good crimping requires a tight profile without gaps, and a regular appearance (re

MC4 is no stranger to photovoltaic practitioners, it has almost become synonymous with photovoltaic connectors. MC4 can be found on important components of photovoltaic power generation such as modules, combiner boxes and inverters, and they are responsible for the successful connection of the power
