The relationship between the energy change of a system and that of its surroundings is given by the first law of thermodynamics, which states that the energy of the universe is constant. We can express this law mathematically as follows: (5.2.4) U u n i v = Δ U s y s + Δ U s u r r = 0. (5.2.5) Δ U s y s = − Δ U s u r r. While monitoring software can often pinpoint PV arrays on a circuit diagram, no efforts were made to label and map the rows of modules. And even when components are labeled, it still takes time to find the strings, because systems are huge these days - and they are only getting bigger. The Z200 PV Analyzer also has a solution for this problem. Solution. Reconnect the AC cable and make sure that the wiring sequence is correct. The AC wire used in the PV system is unsuitable. If an unsuitable cable is selected during the design process, such as an inferior AC cable made from low-grade material or small diameter, problems could arise.
