6 FAQs about [Photovoltaic panel junction box module connection diagram]

What is a solar panel junction box?

A PV junction box is attached to the back of the solar panel (TPT) with silicon adhesive. It wires the (usually) 4 connectors together and is the output interface of the solar panel. How to connect the solar panel junction box to the solar array? With the use of a junction box, it becomes easy to connect the solar panel to array.

What is a PV module junction box?

PV Module's junction boxes with the IP67 protective level, can provide the safety protection for cable and wiring connection, also for contact protection of non-insulating electric parts. Each module has two individual wires connecting the junction box, one is negative pole and the other is positive pole.

What is a photovoltaic junction box?

Most photovoltaic junction boxes have diodes. The function of the diodes is to keep the power flow going in one direction, and prevent power from feeding back into the panels when there's no sunshine. A quality PV junction box is certified (e.g. via TÜV) and regulates the heat and offers reliable long-term safety.

How LONGi Solar module junction box works?

LONGi solar module junction box contains bypass diode which is in parallel connection with the cell string. If hot spot occurred, the diode will come into operation to stop the main current from flowing through the hot spot cells in order to prevent module over-heated and performance loss.

Can a LONGi Solar module junction box be mated together?

Make sure all connectors are fully locked. Only connectors as the compatible model from same vendor can be mated together. Any doubt, please consult LONGi customer service personnel. LONGi solar module junction box contains bypass diode which is in parallel connection with the cell string.

How to connect two modules in a junction box?

Each module has two individual wires connecting the junction box, one is negative pole and the other is positive pole. Two modules can be in series connection by inserting the positive pole at one end of wire of one module into the negative pole of the adjoining module.
