Operation State

"POWER" will light up to indicate that the system is energized and under DSP control.
•
"RUN" will light up when the inverter detects that the grid connection conditions meet the requirements;
•
and power is fed into the grid. "RUN" will blink if the grid is in de-rated running state during the period of
feeding power into the grid. Derate may be caused by low grid voltage, voltage being outside of the MPPT
voltage range window, or excessive temperature.
"GRID" will light up when the grid is normal during the operation of the inverter. Otherwise, "GRID" will
•
blink until the grid restores to normal.
"FAULT" will blink quickly when a fault (except grid fault) occurs. "FAULT" will stay illuminated until the
•
fault is eliminated. The LED will blink slowly when an alarm occurs. "FAULT" remains illuminated when an
internal fault occurs.

Interface Types

Users can perform the corresponding operations with the 4 function keys according to the indications of the LCD.
The LCD screen will display different interfaces based on the operation modes of the inverter. There are four
operation modes: Logo/Start-up interface, Normal operation, Standby, and Fault mode.
(1) Logo/Start-up mode displays the Yaskawa Solectria Solar logo when the inverter is checking if conditions
are met for connection after a manual start-up of the inverter.
(2) Normal Operation mode is the default indication interface for normal operation. In this mode, the
inverter is converting the DC power from the array to AC power, feeding it continuously to the grid.
(3) Standby mode is active when the output voltage and power of PV modules do not meet the startup
conditions or PV voltage and input power are lower than the set value. The inverter will check
automatically whether it meets the startup conditions in this mode until it turns back to Normal
Operation mode.
(4) Fault mode is displayed when the inverter disconnects from the grid due to a fault in the inverter or grid.
Check the Fault log under Current Errors and reference the "Troubleshooting" table in section 7 to
(1) The LCD interface starts with the company logo once the system is energized, as shown in Figure 4-2.
