frequency of the grid and keep the photovoltaic array output at the
maximum power point.
In case of any abnormality, the inverter will enter the protection program
immediately. In low light conditions when power generation is not enough to
keep the inverter in operation, the inverter will enter 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.

Firmware Upgrade
Update the firmware by using the USB flash:
1.
Prepare a USB flash drive (Capacity less than 8G) and format the drive to
FAT32.
a.
Insert the USB flash drive into a compter.
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.
Copy the LCD firmware file and the DSP firmware file into the USB flash
drive. The upgrade file needs to be placed in the root directory. Contact
CPS service for the latest firmware files.
3.
Insert the USB flash drive into USB port on the
inverter’s communications
board.
