Special PID And MPPT Mode Solar Water Pump Controller With 99% MPPT Efficiency
1. Veikong solar pump inverter trial run description
Trial run(How to start solar pump inverter)
Make sure all cables connections of solar panel and pump motor correct and noneed 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 nameplate lf dry run protection is required, measure the unload protection current(see details inuser manual chapter for dry run function) lf dry run protection not required then miss this stepand 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 runningmore than 40 Hz. Please disconnect the power supply and replace any two-phase wiring ofthe motor

5. Technical Questions and solutions
1) How to achieve Automatic start after stop? If it is controlled by keyboard,so there is no need to set any parameter(P47.03 waiting time)If you want to control by external switch,First set P00.06=1 and use a wire or switch to connect com and DI1,When the switch is closed, the drive run, when the switch is open, the drive stop
2) How to use a float in the water tank to stop the pump if the tank is full? If your float signal is digital signal Use float switch to short DI 3 and com ,see diagram 1.3 15
3) Use level probe in the well for protection against dry running
1 st solution: See self learning of dry run(For LED display)
2 nd solution: do it manually Set P24.13=30%-60%(as per real empty load current percentage based on rated current) and P24.14 P24.16 and P23.21
3 rd solution: If your sensor is digital switch ,just short D4 and com
4 th solution:If your float signal is Analog signal, Connect Ai2 and 10V and GND and set P41.00=23 and P41.03-P41.06
