Solar storage system, including solar modules, controllers, inverters, batteries, loads and other equipment. At present, there are many technical routes, but the energy needs to be collected at a certain point. At present, there are mainly two topologies of DC coupling "DC Coupling" and AC coupling "AC Coupling". 1, DC coupling As shown in the figure below, the DC power generated by the photovolta...
What is a DC arc? Arc is a kind of gas discharge phenomenon, the instantaneous spark generated by the current passing through some insulating medium, such as air, this is the arc. Both direct current and alternating current produce arcs. Sometimes when we plug in the socket, we will see a fire, which is a kind of AC arc. In a DC system, such as that caused by a string of photovoltaic cells, this a...
