MPPT Solar Water Pumping
The Veichi 4kW Solar Pump Inverter uses Maximum Power Point Tracking (MPPT) to make efficient use of power available from the solar PV array.
As sunlight changes during the day, the inverter adjusts its output frequency and pump operation according to the available solar energy. Veichi specifies maximum MPPT efficiency of up to 99.8% for the SI23 SS2 platform.
This allows the pumping system to operate directly from solar power during suitable daylight conditions without requiring batteries for normal water pumping.
Designed for 4kW Water Pump Systems
The Veichi 4kW inverter is designed for pumping systems where the pump motor and inverter are correctly matched according to power, voltage, current and motor configuration.
The 4kW SS2 configuration has a rated output current of 30A, providing the current capacity required for compatible low-voltage pump installations.
Veichi’s SS2 software also includes dedicated control modes for:
- Three-phase motors
- Single-phase pumps using single-phase control
- Single-phase pumps using two-phase control
This makes the platform suitable for compatible single-phase pump motors when correctly configured and wired according to the manufacturer instructions.
Hybrid Solar and AC Operation
The Veichi SI23 supports hybrid solar and AC operation, providing greater flexibility for water-pumping systems.
Solar PV provides the primary source of energy during suitable daylight conditions, while an AC supply from the grid or a compatible generator supports pumping when solar production is insufficient. Veichi lists AC/DC mixing as one of the SI23’s dedicated solar-pumping functions.
Hybrid operation is particularly useful for farms, boreholes and water-supply installations that require longer pumping hours or dependable water availability throughout changing weather conditions.
Where to Use the Veichi 4kW Solar Pump Inverter
The Veichi 4kW Single-Phase Hybrid Solar Water Pumping Inverter is ideal for:
- Borehole water pumping
- Agricultural irrigation
- Drip irrigation systems
- Sprinkler irrigation
- Greenhouse irrigation
- Livestock watering
- Water pumping to storage tanks
- Farm water-distribution systems
- Residential water supply
- Commercial water supply
- Community water projects
- Remote and off-grid pumping systems
Veichi identifies applications including farmland irrigation, residential water supply and other solar-powered water-pumping systems for the SI23 range.
Solar Panel Requirements
Correct solar-array sizing is essential for reliable operation of the Veichi 4kW Solar Pump Inverter.
For the SI23 SS2 configuration, Veichi specifies:
- PV input voltage range: 150–450V DC
- Recommended PV Voc: 360–430V DC
- Maximum MPPT efficiency: up to 99.8%
The solar array should be designed using:
- Solar panel wattage
- Panel Voc
- Panel Vmp
- Number of panels connected in series
- Number of parallel strings
- Cold-temperature corrected array Voc
- Pump motor power
- Pump rated current
- Site solar conditions
The complete PV string must remain within the permitted inverter input-voltage range under actual operating conditions.
Pump and Inverter Matching
Selecting an inverter because the pump is labelled 4kW is not enough.
A dependable solar water-pumping system should be designed around:
- Pump motor power
- Pump motor voltage
- Pump rated current
- Pump phase and winding configuration
- Borehole depth
- Static water level
- Dynamic water level
- Total dynamic head
- Required water flow rate
- Pipe diameter and length
- Solar array voltage and power
For a new borehole or irrigation installation, determine the required head and flow first, select the correct water pump, and then match the Veichi inverter and solar array to the electrical requirements of that pump.
Pump Protection Functions
The Veichi SI23 includes extensive protection functions for both the inverter and water-pumping system.
These include:
- Undervoltage protection
- Overvoltage protection
- Input/output phase-loss protection
- Overload protection
- Overcurrent protection
- Drive over-temperature protection
- Short-circuit protection
- Low-frequency protection
- Pump overcurrent protection
- Dry-run protection
- Minimum-power protection
- Overflow protection
- Sleep protection
These functions make the inverter well suited to automatic borehole and irrigation systems where the pump may operate for extended periods with limited supervision.
Single-Phase Pump Control
The Veichi SI23 SS2 platform provides dedicated control for compatible single-phase pumps.
Veichi’s current manual includes both single-phase motor single-phase control and single-phase motor two-phase control options. The correct setting and wiring depend on the pump motor’s winding and capacitor arrangement.
For this reason, the pump nameplate and motor wiring should always be checked before commissioning the inverter.
Installation Requirements
The Veichi SI23 is an IP20 inverter with forced-air cooling and is designed for installation in a protected electrical environment. Veichi specifies environmental limits and requires derating under certain high-temperature and high-altitude conditions.
For borehole, irrigation and outdoor installations, the inverter should therefore be installed inside a suitable electrical enclosure with adequate ventilation and protection from rain, moisture, dust and direct weather exposure.
What to Check Before Ordering
Before purchasing the Veichi 4kW Single-Phase Hybrid Solar Water Pumping Inverter in Kenya, confirm:
- Exact Veichi model and configuration
- Pump motor power
- Pump motor voltage
- Pump rated current
- Pump phase and winding configuration
- Borehole depth
- Static and dynamic water levels
- Required total dynamic head
- Required water flow rate
- Solar panel wattage
- Solar panel Voc and Vmp
- Solar array string configuration
- Maximum PV array Voc
- Grid or generator backup requirements
- Water-level sensor requirements
- Tank-level control requirements
- Cable sizes and cable distances
- Required DC and AC protection
- Electrical enclosure and ventilation requirements
Correctly matching the pump, Veichi inverter and solar PV array ensures reliable pumping performance and keeps the complete system within its designed electrical limits.
