Solar panels in series with 48 volts voltage
1, Connecting six solar cells can feasibly achieve a 48-volt output by arranging them in series, 2, The series configuration allows each solar cell to contribute to the overall voltage, thus reaching the desired output, 3, Each standard solar cell typically has a voltage output of around 6 volts, meaning that combining a sufficient number in series can successfully yield 48 volts, 4, Furthermore, care must be taken to ensure the cells are matched in voltage and amperage to optimize performance and efficiency.

Inverter AC side voltage is high
According to the requirements of the overvoltage/undervoltage protection on the AC output side of the photovoltaic power grid-connected inverter technical specification (NB/T32004-2018): When the voltage at the AC output end of the inverter exceeds the allowable voltage range of the power grid, the inverter is allowed to disconnect the power supply to the power grid, and a warning signal should be issued when it is disconnected.
