What connectors do solar panels use?

MC4 connectors are single-contact electrical connectors commonly used for connecting solar panels. The MC in MC4 stands for the manufacturer Multi-Contact (now Stäubli Electrical Connectors) and the 4 for the 4 mm diameter contact pin.

Are all solar panel connectors the same?

These solar panel connectors are available in male and female types made to snap together. Connectors are of various types, the major ones being MC3, MC4, PV and Tyco Solarlok. Similarly, they come in many shapes such as T-Joint, U-Joint, X-Joint or Y-Joint. The most common type of solar connector is the MC4 connector.

PV panels are a source of power so connecting them backwards, at least in daylight, is more likely to damage your circuits than damage the panel.

How do you tell the positive and negative terminal of a solar panel?

Another way to find the polarity of the solar panel is to check with a volt meter. A simple voltage reading will show you the polarity of a solar panel, even when inside. To measure across the solar panel terminals or wires, put the red positive meter lead on one side, and the black negative on the other.

How do I know if my solar inverter is working?

A simple health check is to look at the colour of the lights shining on the box during daylight hours when the system’s meant to be running. A green light on your inverter means your system is functioning properly. A red or orange light during daylight hours means there’s a system event or fault.
