MC4 Connectors

These are single-contact connectors commonly used for connecting solar panels. MC4 stands for the manufacturer Multi-Contact USA and a 4 mm2 contact assembly pin.

WARNING!!! It is very important to never connect or disconnect under load, even at low voltage (12-48 V). An electric arc can form, which can melt and seriously damage the materials in contact, leading to high resistance and subsequent overheating.

MC4 means the manufacturer Multi-Contact USA

Photovoltaic Junction Boxes

Allows connecting 4 or 5 photovoltaic panels (in parallel) into a single box that protects their connections.

only box that protects their connections

Solar Cables

There are different thicknesses of solar cables: 2.5mm, 4mm, 6mm

Solar Trackers

The operating principle is to orient towards the Sun throughout the day, which significantly increases energy production. Indeed, the position of the sun constantly varies, both during the day and throughout different times of the year. The tracker thus allows optimal positioning of the panel relative to the Sun's position.

Power Optimizers

An electronic box individually connected to the photovoltaic panel, the power optimizer allows optimizing the panel in all situations, such as shadow passages, etc

AC or DC Surge Protection Boxes

A surge protection box is designed to protect the equipment of a domestic photovoltaic installation against lightning and overvoltage.

Frequently Asked Questions

What are MC4 connectors used for in solar panels?

MC4 connectors are single-contact connectors used to connect solar panels. They ensure a secure and waterproof connection between solar modules and the electrical system. It is important to never connect or disconnect under load to avoid any electrical arc that could damage the components.

What is a photovoltaic junction box?

A photovoltaic junction box allows connecting several solar panels (usually 4 to 5) in parallel. It protects electrical connections from weather conditions and reduces the risk of short circuits or oxidation.

What thicknesses of solar cables are available?

Solar cables are available in different thicknesses, notably 2.5 mm², 4 mm², and 6 mm². The choice of thickness depends on the distance between the panels and the regulator, as well as the current intensity to be carried to minimize electrical losses.

How does a solar tracker work?

A solar tracker is a device that automatically adjusts the orientation of solar panels to follow the sun's path throughout the day. This optimizes energy production by maintaining an optimal angle relative to the sun's rays.

What is the role of a power optimizer in a solar installation?

A power optimizer is an electronic box installed on each solar panel. It maximizes the energy production of each module independently, reducing losses related to partial shading or performance differences between panels.

Why use an AC or DC surge protection box in a solar installation?

A surge protection box protects the electrical components of the solar installation against overvoltages caused by lightning or voltage spikes. It is essential to secure the equipment and extend their lifespan.
