When the debugging mode is 2, the inverter is in vector mode + economic
mode, which is vector control mode and economic operation mode.
When the debugging mode is 3, the inverter is in VF mode + economic mode.
In this mode, it is VF control mode and economic operation mode.
When operating in these two modes, when the system is jointly powered by
photovoltaic and power grid, the inverter gives priority to photovoltaic energy,
when photovoltaic output frequency & LT;
When the power grid access frequency (which can be set), the inverter takes
the initiative to connect the power grid to meet the operating requirements of
the system;
With the increase of pv power, when PV power & GT;
When the power grid exits (configurable), the inverter will take the initiative to
exit the power grid
7.3 Modify motor parameters
After initialization, enter into critical parameters’ setting, check inverter default with pump
motor parameters, including : “U-Rated”, “I-Rated”, “P-Rated”, “F-Rated”, “RPM-Rated”,
“PF-Rated”, and modify the inconsistent default of inverter.
Please refer to “
8.3.2.2 DSP parameter setting
”for system critical parameters’
setting.
The default motor parameters are shown as the below table 7-1.
