Shut-Down
Automatic shutdown: The inverter will be shut down automatically when the output voltage and power of PV
modules are lower than the set value, AC power grid fails, or the ambient temperature exceeds the normal range.
Manual shutdown: Normally, it is not necessary to shut down the inverter, but it can be shut down manually if
regulation setting or maintenance is required.
Press ESC and then ENT to access the
press ENT. Move the cursor to "OFF" and press ENT, and then the inverter will shut down.
Grid-tied Power Generation
The inverters have an automatic grid-tied power generation process. It constantly checks whether the AC grid
meets the conditions for grid-tied power generation and test whether the PV array has adequate energy. After all
conditions are met, the inverter will enter into Normal Operation mode and export power to the grid. While
generating power, the inverter can detect the grid at all times, supply current, match the voltage and frequency of
the grid, and keep the photovoltaic array output at the maximum power point. In case of any grid abnormality,
the inverter will enter the protection program immediately. In low light conditions when PV power generation is
not sufficient to keep the inverter in operation, the inverter will enter into standby mode. When the voltage of PV
array changes, becomes stable and higher than the required start value, the inverter will attempt to start grid-tied
power generation again.
File Export (local)
File Export is used to export the data including Running History and Fault Record to a flash drive. Press ENT and
use UP and DOWN arrows to export the data, and press ENT to confirm the setting.
Firmware Upgrade
Update the firmware by using a USB flash drive:
1. Obtain a USB flash drive (Capacity less than 8G) and format the drive to FAT32.
a. Insert the USB flash drive into a computer.
b. When the USB drive appears in the File Explorer Right click the drive and select "Format...". The File system
should display "FAT32" as default. If not, make this selection and click "start."
2. Obtain a copy of the LCD firmware file and the DSP firmware file from Yaskawa Solectria Solar's technical
support team and copy them into the USB flash drive. The upgrade files need to be placed in the root
directory. Contact Yaskawa Solectria Solar's after-sales technical service team for the latest firmware files.
3. Insert the USB flash drive into USB port on the inverter's communications board.
