Product Application

 

 

Trial run(How to start solar pump inverter)

Make sure all cables connections of solar panel and pump motor correct and no

need to set any parameter, if you want to set parameter, you can do as follows.

 

Step 1: (Keypad control):Set motor parameter P11.02- P11.06 as per motor pump name

plate If dry run protection is required, measure the unload protection current(see details in

user manual chapter for dry run function) If dry run protection not required then miss this step

and go to step 2.

 

Step 2: Set other related special solar pump parameters for optimization if needed.

 

Step 3: After trial run finishing, if motor pump still not output water when inverter is running

more than 40 Hz. Please disconnect the power supply and replace any two-phase wiring of

the motor

 

PMSM pump

Synchronous motor must be self-learning of motor parameters, otherwise there will be a risk

of flying,

P11.00=1 set to synchronous motor(special software)

P11.02=motor nameplate power

P11.03=Motor nameplate voltage

P11.04=Motor nameplate current

P11.05=motor nameplate frequency

P11.06=Motor nameplate speed

P11.22=Back EMF on the motor nameplate

If there is no such parameter on the nameplate, you can try to set 300V 350V for self

learning (try self-learning for 380v level)

The difference between the back-EMF setting value and the actual value should be less

than 20%, otherwise the self-learning will be abnormal

After the parameter setting is completed, set P11.10=2, press RUN then the keyboard

appears Tune for self-learning.
