EmailSI32 Solar Water Pumping Inverter Overview
SI32 series solar water pumping inverter is the latest pump inverter developed by VEICHI.
Product Features
IP65 for SI32 Series
- Secured waterproof design for durable and reliable operation.
- Outdoor application with AC and DC input for continuous operation.
Max. power up to 22kW
A wide range of motor types compatible up to 6,500rpm for high-efficiency operation.
Anti-reverse connection and anti-backflow
Enhanced the system security for lower potential risks due to improper operation or unforeseen circumstances.
4 flexible control modes integrated for constant pressure operation
- Easily set F22.03 [Application Macro]=3 for speed mode, pressure mode, pressure start/stop mode, and timer mode.
- Among them, the speed in the speed mode and time mode is decided by the speed parameters while the speed of pressure mode is regulated by PID control.
PID Disconnection Detection
1. Robust safety guarantee in pressure mode and pressure start-stop mode.
With reference to the alarm threshold setting, the system is able to ensure pressure control accuracy while responding to potential faults and hazardous situations, improving overall efficiency and safety.
2. Multiple pressure sensors
Built-in common sensor types and ranges are free to be changed by users.
3. Real-time monitoring and control of water levels in wells and cisterns by float switches
The float switch triggers a signal to start the pump when the cistern drops to a certain level, and stops it when the water level reaches the upper limit, thus maintaining the water in a reasonable range, and at the same time, it can prevent the pump from idling work when there is less or no water at all in the well.
MPPT efficiency up to 99.8%
Maximize the efficient capture and conversion of solar energy with minimal energy loss.
Product Application
Agricultural irrigation, desert governance, grassland livestock, urban springs, household water.
