To choose the best technology for surge protective devices, we should consider the following technical parameters (include but not limited to):
1. Type of surge protective devices according to EN61643-11/IEC 61643-11
2. Nominal Voltage (Un)
3. Maximum Continuous Operating Voltage (Uc) /Maximum Continuous Operating Voltage for PV System (Ucpv)
4. Voltage Protection Level (Up)
5. Nominal Discharge Current (In)
6. Maximum Discharge Current (Imax)
Solar connectors are an essential part of any solar panel installation. They allow for the transfer of electricity from the panels to the inverter and then on to the grid or battery system. There are many different components that make up a solar connector system, including the male metal crimp, the male plastic housing, the female […]
If you’re interested in setting up a solar system, it’s important to understand how to identify the correct type of solar connector. There are four points for you to consider: 1. Types of Solar Connectors There are two types of solar connectors: male and female. Male connectors have pins that go into the socket of […]
ommon mode SPD between phase and PE or phase and PEN is installed whatever type of system earthing arrangement (see Fig. 1). The neutral earthing resistor R1 used for the pylons has a lower resistance than the earthing resistor R2 used for the installation. The lightning current will flow through circuit ABCD to earth via […]
