Shutdown Mode
Inverters automatically stop running during periods of little or no sunlight. In shutdown mode the inverters take no
power from the grid and panel, and the LCD and LED turns off.
Notes: If the PV string DC voltage is too low, the inverter will also turn to Shutdown Mode.
Derating mode
When AC frequency is higher than 50.3Hz(settable), the inverter will derate its output power according to the rule.
When user set the output limit command to the inverter, the inverter will also limit the output according to the
setting.
In this derating mode, the LCD will show “DERATING”.
