Is the grid side of the grid and the inverter?
Grid-type system power transmission sequence: photovoltaic panels> relays> inverters> relays> electricity load + power grid (both in parallel).
Off-grid system power transmission sequence: photovoltaic panels> relays> inverters> relays> electricity load;
The grid load side of the grid is the grid. The inverter is an important part of the PV grid-connected system and can not be regarded as an external load. Photovoltaic power generation system is included in both grid and off-grid.
