MC4 connectors are single-contact electrical connectors commonly used for connecting solar panels. MC4s allow strings of panels to be easily constructed by pushing the connectors from adjacent panels together by hand, but require a tool to disconnect them to ensure they do not accidentally disconnect when the cables are pulled. The MC4 and compatible products are universal in the solar market today, equipping almost all solar panels produced since about 2011. Originally rated for 600 V, newer versions are rated at 1500 V, which allows longer strings to be created.
Surge protective devices are crucial components of any electrical installation. They play a vital role in protecting your devices and equipment from voltage spikes and surges. But what are they exactly? In this blog post, we’ll take a closer look at surge protective devices and why they are essential for your home or business. […]
