Selection of Bypass Diodes

The diode in the photovoltaic junction box is used as a bypass diode to prevent the hot spot effect and protect the components. The selection of bypass diodes mainly needs to follow the following principles: 1. The withstand voltage capacity is twice the maximum reverse working voltage; 2. The current capacity is twice the maximum reverse working current; 3. The junction temperature should be higher than

Precautions for junction box installation

The junction box should be tested before use. The main items are appearance, sealing, fire resistance level, whether the diode is qualified, etc. The test is as follows: 1. Appearance: size, with or without defects, operate by the incoming inspection work instructions 2. Mechanical properties: the tension between guide and bus bar; clamping force at diode angle; tension between wire and junction box; tension

How to install a solar junction box

The solar junction box is essential because it connects your solar panel to the outside world and protects your connections from outside the solar panel. Its second purpose is to give you an easy way to connect and disconnect solar panels for maintenance or repair or create a series of solar panels (solar arrays) together. Additionally, it adds an overall professional look to the entire panel. Before installation,
