The low voltage grid tied scenario applies to small and medium-sized rooftop power stations that are small in size and generally the electric energy yield is lower than 1MW.
Usually, for the AC side, the wye connection is used with a N cable. The power grid quality is relatively poor with high harmonic content and RS485 communication is recommended, but PLC communication can also be used.
