Disassembly of the photovoltaic panel junction box

What are the warning tips when using a solar panel junction box?

Some of the warning tips when using a solar panel junction box include: Do not open the junction box: The junction box is designed to be sealed and should not be opened by anyone except a qualified technician. Attempting to open the box can be dangerous as it may expose live electrical components, increasing the possibility of electric shocks.

What are the components of a solar panel junction box?

The major components of solar panel junction boxes include enclosure, diodes, terminal blocks, and surge protection devices. These components all have their part to play in the junction box's overall performance. Below is a detailed introduction to them: The enclosure serves two main purposes: connection protection and durability.

What are surge protection devices in solar panel junction boxes?

Surge protection devices in solar panel junction boxes help to protect connected electronic components from dangerous voltage fluctuations. These devices divert excess electricity away from the sensitive components within a junction box, making them crucial for maintaining the performance and longevity of a solar array.

What is the difference between a junction box and a combiner box?

A junction box routes power from each solar panel into strings, while a combiner box aggregates multiple solar panel strings together, combines those inputs, and routes the total combined power output to the main inverter or grid connection. What are the different types of solar junction boxes?

How do you fix a defective junction box?

Pry open the defective junction box lid using a screwdriver. Dig out the potting gel to expose the soldering point. Melt the residual tin with an electric soldering iron, lift up the ribbon, and separate it from the junction box. Use a scraper to remove residual silica gel, ensuring no damage to the ribbon.

How do you remove silica gel from a junction box?

Lift up the junction box terminal and insert the scraper into the silica gel to loosen it. Pull the cable toward the nearest frame to detach it from the back sheet. Remove any remaining silica gel using the scraper. Use needle nose pliers to make the ribbon perpendicular to the back sheet.
