7.5 Inverter Operation Mode Switch
There are two kinds of operation mode of Inverter, one is Vector Control as default, and
the other one is VF Control. If you want to try VF, or the performance of Vector is not
good, please refer to the following step:
First: Stop inverter, and ensure it’s standby;
Second: Refer to “8.3.5.3 Key Parameters of the System Set ” to set the
“DebugMode” as “3”;
Third: Refer to “8.3.5.3 Key Parameters of the System Set ” to set the “Run-Mode” as
“CVT”;
Forth: Set the “UINST” as “0.85*“Vin””(standby);
Fifth: Return to main interface, long-press “ON/OFF” for 4S to start inverter.
7.6 Overload current setting
After the success of first commissioning, please refer to “8.3.5.3 Key Parameters of the
System Set ” to set the “Imotor” as 1.1 times of “I-Rated”.
7.7 Stop Frequency Setting
Solar pumping system for the first time trial run is successful, need to set the system
shutdown frequency, as follows.
Step 1: Ensure the system is running and there has water output. To enter “StopFreq”
interface. Please refer to “8.3.5.3 Key Parameters of the System Set”.
Step 2: To reduce the value of “StopFreq”. Reduce 5 each time (every change need to
press “ENTER” to confirm). Keep reducing till there just has no water output, and
make a small change to just get small water come out, and the value is the very
data of “StopFreq”.
Step 3: Escape the “StopFreq” interface.
Finish the debugging.
