running at full power, the grid exits .
When the debugging mode "2" is selected, it means that the inverter is in the
pure photovoltaic mode, and the power grid cannot be connected, and only
photovoltaic energy is used for operation.
When the debugging mode is "4", the inverter is in the motor detection mode,
which needs to be modified only for single -phase pump load. After the motor
parameter detection is completed, the debugging mode is automatically modified
to "0".
The inverter generally defaults to three -phase output. If the pump load is
single-phase pump, special parameters of the inverter shall be set as follows:
● When the output is connected to the single -phase pump and the system is
powered on, the inverter "parameter setting" interface needs to be entered. The
"output selection" of the inverter is modified to "1" (" 0 "represents the
three-phase inverter output," 1 "represents the single -phase inverter
output).After modification, the inverter must be switched off and powered on
again. For specific modification steps, please refer to t
he chapters of “8.3.2.2
DSP Parameter Setting” and “8.3.4 Parameter Setting”.
● After power on and restart, change "Debug mode" to "4".Please refer to the
section "8.3.2.2 DSP Parameter Setting" and "8.3.4 Parameter Setting" for
specific modification steps.
Long press the "ON/OFF" key ON the inverter panel for 3 seconds, the "RUN"
light will always be ON after flashing, the inverter will start to RUN, and the
system will work (if the load is single -phase pump running for the first time,
select "Yes" after motor parameter detection, and the inverter will start to
RUN).At this point, it is necessary to check whether the photovoltaic pump
system is working normally and whether it can reach the head and flow of the
system .After running for a period of time, press the "ON/OFF" key ON the LCD
