metal junction box

The stainless steel junction box is a connection device between the solar panel array and the solar electrical control equipment, and is an indispensable and important part of photovoltaic power generation.

Each solar cell module needs to be equipped with a set of metal j boxes and a pair of connectors, which play a key role in the connection and protection between components.

The role of metal junction box

With the continuous growth of battery module power, the battery conversion efficiency has also been improved year by year, and the working current in the photovoltaic system has been significantly improved.

As an important connection and protection device between battery modules, the junction box is responsible for the power output and line protection of photovoltaic modules. In order to ensure the use needs, the junction box is required to have a higher current carrying capacity. The current carrying capacity is closely related to many indicators such as heat dissipation, conduction efficiency, and reliable tolerance.

Therefore, HY always keeps synchronous technological innovation in the process of producing photovoltaic module junction boxes to adapt to the rapid development of battery cell technology. The photovoltaic module junction box is developing towards higher current carrying capacity, better heat dissipation, higher system stability, and lower production costs.

Features of solar metal junction box

(1) The shell is made of imported high-grade raw materials, with extremely high anti-aging and UV resistance;

(2) It is suitable for use in harsh outdoor environments, with a service life of more than 30 years;

(3) 2 to 6 wiring terminals can be built in as needed;

(4) All connection methods are connected by quick-connect plug-in.

Material selection and process of metal junction box

According to relevant national standards and requirements, as well as the product's usage scenario environment, such as corrosion resistance, high temperature resistance, extreme climate resistance and other properties, select appropriate steel, aluminum alloy, plastic, etc.

1. Steel plate or aluminum alloy materials need to be processed by shearing, bending, stamping and other processing to complete the required shape structure.

2. After the processing is completed, surface deburring, grinding and other processing are required to ensure that the product surface is smooth and flat.

3. Assemble the processed components, including combination, fixing, wiring, etc., and conduct overall inspection after assembly to ensure that the product quality meets the requirements.

4. Inspect the electrical and mechanical properties of the product to ensure that the product quality is stable and reliable. Including appearance inspection, electrical performance inspection, reliability test, etc., and only after passing the inspection can it be packaged and shipped.
