24. When the power station is shut down, should the PV side switch be turned off first or the grid side switch be turned off first? Which side switch should be turned on first when generating power and sending it to the grid?
Answer: When the PV power station is shut down, turn off the DC (module side) first, then turn off the AC (inverter side); when sending power to the grid, turn on the AC first, then turn on the DC. AC is always ahead.}}
