shutdown frequency, as follows.
Step 1: Ensure the system is running and there has water output. To enter
“StopFreq”
interface. Please refer to "8.3.2.3 DSP Parameter Settings" " 8.3.4
parameters " .
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: Exit
the “StopFreq” interface.
Finish the debugging.
Note
！
The set of “StopFreq” can ensure inverter stop working when the output power of
PV array is too weak to pump water, which can increase the pump’s lifespan.
