This is for a commercial project, and The owner had 2-POI (one-1600A and the other is 1000A).
option-1, In this option, we used the two transformers (one step-up and step-down transformer) and run a low-ampacity cable.
option-2, we use the 12 nos of inverter and 4 combiner panels (each panel has 3 inverters) and run the high ampacity cable.
Please suggest to me which option is cost-effective and has more reliable and low losses.
I really appreciate it, and Thanks in advance.
