WebbThe supplying solar PV array consists of 20 parallel-connected PV-strings. Each string consists of 30 series-connected PV-modules, each of them having a maximum Voc of 28.4 VDC and an Isc rating of 7.92 A. The highest inverter power output is obtained at the maximum power point, which occurs with approximately 146 A (IMPP) at the inverter input. Webb13 nov. 2024 · A simple formula is as follows: 200A buss bar (as shown on the sticker) X 120% = 240. Then, take 240 minus 200 (main breaker) = 40A. Since we need 40A of back … Webb13 aug. 2015 · Technically, you need to have the backfed breaker all the way at the other end of the bus, with nothing beyond it, to qualify to use the 120% rule. The 120% rule allows the sum of the main breaker rating and the PV backfeed (output rating or breaker size depending on code year) to be as much as 120% of the rating of the bus bar in the panel. ny uniform procedures act
