Multi Protection Single Phase Solar Pump Inverter With 50Hz 60Hz Output
Multi-Protection Function Single Phase Solar Pump Inverter With 50/60Hz Output
1. Veikong solar pump inverter
1) Support hybrid mode, means both DC and AC input,with hybrid function,when DC power not enough , AC will do compensation.
2) Support GPRS function, GPRS system support 2G/3G/4G for both PC and phone.
3) Maximizing power generation efficiency of solar modules with the use of advanced MPPT control technology and automatic MPPT voltage tracking.
4) Advanced calculation for Pump flow and LCD monitoring display.
5) Automatic running without any commissioning in keypad control and optional GPRS monitoring.

4. 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
3) Use level probe in the well for protection against dry running
1st solution: See self learning of dry run(For LED display)
2nd 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
3rd solution: If your sensor is digital switch ,just short D4 and com
4th solution: If your float signal is Analog signal, Connect Ai2 and 10V and GND and set P41.00=23 and
P41.03-P41.06
4) How to set minimum frequency ( for example) 30hz and maximum 50HZ
Set P47.05=30HZ and 47.06 to some time and 47.07 to some time. Please refer to details of P47.05-47.07
5) If pump is 60HZ frequency, how to set max frequency?
Notice: If your motor rated frequency is 60HZ First solution for you, P01.06=P01.08=P11.05=60HZ.
Quick setting and easier way: you should set P00.11=02 If your motor is three phase; if your motor is single phase with capacitor ,set P00.11=22;If your motor is single phase without capacitor ,set P00.11=32
6) Does the product need to set a lot of parameters?
No, it doesn't. The inverter has a self-adaptive and self-learning function. It is automatic start and stop, you can press Run key to start, or you just wait for P47.03=60S(Default) then it will automatically start
