stands by.
Automatic start-up: The inverter will start up automatically when the
output voltage and power of PV modules meet the set point, AC power grid is
normal, and the ambient temperature is within allowable operating range.
4.1.2 Shut-down
Manual shutdown : Normally, manual shutdown is not required. It can be
shut down manually if repair or maintenance is required. Move the cursor from
the main operation interface to “4 Setting”. Press ENTER and go to the

output voltage and power of PV modules are lower than the set point, or AC
power grid fails; or the ambient temperature exceeds the normal range.
