Key Advantages:
1. MPPT efficiency more than 99%.
2. Drives well all 1/3 phase AC pumps and PMSM in solar pumping system.
3. Voc of solar panel can set by manual or MPPT automatically tracking.
4. Solar DC & Grid AC power supply input both ok.
5. Dry run & Full water tank protection.
6. Short circuit, over load, over current... motor production.
7. The PQ (power/flow) performance curve enables calculating the flow output from the pump
8. Ambient temperature for using: -10 to +50˚C.
9. Inverter Power range: 220V, 0.75KW to 110KW. 380V/480V, 0.75KW to 250kw
Techincal Parameters:
1. Wake up and sleep function parameters:
| P47.05 | Light detection threshold | If the output frequency is lower than this value and exceeds P47.06, it will be reported to Sleep and stop | 0Hz |
| P47.06 | Light detection time | See P47.05 for explanation. | 60s |
| P47.07 | Light weak wake up time | After the sleep fault is reported, if the time when Vdc is higher than the undervoltage point is greater than the set value, the fault state is exited and the operation continues. | 600s |
2. Dry runing protection function parameters:
| P24.12 | Dry run/Unload protection option | 0: No offload detection is performed; 1: Enable dry run detection | 1 |
| P24.13 | Dry run/Unload detection level | 0.0 to 200.0% The percentage of motor rated current. | 0.0% |
| P24.14 | Dry run Unload detection time | 0.000s～60.000s | 30.000s |
| P24.15 | Unload detection offset frequency | 0.00Hz～Fmax Detection frequency=Fmax-P24.15 | 5.00Hz |
| P24.16 | Reset time of dry run protection | 0.0～6000.0 | 240.0s |
| P23.21 | Dry run detection mode | 0000:Coast stop 1000:Fast stop 3000:Continue to run | 0000 |
3. Water full protection function parameters:
| P47.18 | Full water level detection channel | 0:ineffective 1:AI1 2:AI2 3:AI3 4:AI4 Note: DI terminal function code 60-full water level detection is same with Analogue detection, and the detection time and recovery time are the same. | 0 |
| P47.19 | Full water level detection value | 0.0～100.0% | 0.0% |
| P47.20 | Full water level detection time | 0.0～3000.0s When DI-60 is valid or meets the analog detection channel greater than P47.19 and maintains P47.20 time, the system reports A.Full and stops. | 10.0s |
| P47.21 | Full water recovery time | 0.0～3000.0s When the condition described in P47.20 does not meet full water level detection requirement ,it will be returned to normal state after delay | 10.0s |
