MC4 Solar Connector is the name of the connection type on all new solar panels, providing an IP67 waterproof and dust proof safe electrical connection. MC4 Solar Connector will not connect with older MC3 type Connector. The MC4 Solar Connector work best with 4mm and 6mm solar cable. The picture above shows all the parts […]
In modern power systems, the use of direct current (DC) power supplies is becoming increasingly popular, especially in areas such as renewable energy and electric vehicles. With the widespread use of DC power supplies, the risk of overvoltage faced by electrical equipment has also increased. Therefore, DC surge protective devices (SPDs) have become an important tool for […]
Knowing individual surge components is helpful to understand, but what drives the standards for SPDs are performance aspects or features for each device. After identifying the power distribution system to which the SPD is to be connected, one should compare different available devices by the following: 1. Maximum Continuous Operating Voltage (MCOV). The MCOV is the […]
