Ensure that the AC and DC terminals are connected firmly.
●
Check whether the system pipeline is unobstructed or not;
●
Switch on the DC-side circuit breakers.
After finishing the above steps, then begin initialization.
According to the pump motor rated current value on the nameplate, setting inverter
overload protection value, the method is: modify the “Imotor” value equal to 1.2 times of
the motor rated current, the details please refer to chapter “8.3.4.3 Key Parameters
of the System Set”. "Imotor" settings.
After finishing the above steps, machine shall start operation after long -time
pressing the
“ON/OFF”
key for 4s; check if the solar pumping system works
properly or realize suitable head of delivery and flow. Press
“ON/OFF”
and

●
Output power of inverter drives the pump working; the pump will stop
working while the inverter stops.
●
AC side circuit breaker must be turned off during operating.
