A solar water pumping inverter is the core component that converts solar power into usable electricity for running water pumps. It enables efficient water pumping for boreholes, irrigation, livestock, domestic supply, and commercial farming, without relying on grid power or fuel.
At Solar Energy Suppliers, we provide reliable solar water pumping inverters in Kenya, designed for harsh weather conditions and long operating hours.

What Is a Solar Water Pumping Inverter?
A solar water pumping inverter is a specialised variable-frequency drive (VFD) that:
- Converts DC power from solar panels into AC power
- Adjusts voltage and frequency to match pump requirements
- Optimises pump performance based on available sunlight
- Protects the pump from electrical and mechanical damage
Unlike standard inverters, solar pumping inverters are purpose-built for motor control and water systems.
How Solar Water Pumping Inverters Work
Working Principle:
- Solar panels generate DC electricity
- MPPT inside the inverter maximises solar output
- Inverter converts DC to AC at variable frequency
- Pump speed adjusts automatically based on sunlight
- Water is pumped efficiently throughout the day
This ensures maximum water output even during low sunlight.
Types of Solar Water Pumping Inverters
1. DC Solar Pump Inverters
- Used with DC pumps
- High efficiency
- Ideal for small to medium systems
2. AC Solar Pump Inverters
- Works with AC borehole and surface pumps
- Suitable for deep wells and high-flow irrigation
3. Hybrid Solar Pumping Inverters
- Supports solar + grid + generator
- Ensures water availability 24/7

Solar Water Pumping Inverters for Kenya’s Needs
Kenya’s agriculture and water sectors benefit greatly from solar pumping inverters, especially in:
- Arid and semi-arid areas (ASAL regions)
- Off-grid farms and ranches
- Boreholes and community water projects
- Greenhouses and drip irrigation systems
Solar pumping systems are widely used in irrigation, livestock watering, domestic supply, and commercial farming.
How to Choose the Right Solar Water Pumping Inverter
| Factor | What to Consider |
| Pump Power | HP or kW rating |
| Pump Type | Submersible or surface |
| Voltage | Single-phase or three-phase |
| Solar Array Size | Panel wattage |
| Water Head | Depth and pressure |
| Hybrid Option | Grid/generator backup |
Proper sizing ensures maximum efficiency and long-term reliability.
Installation & Maintenance Tips
- Conduct a site survey before installation
- Use correct cable sizes and DC protection
- Mount inverter in a shaded, ventilated area
- Regularly clean solar panels
- Inspect wiring and grounding periodically
Always work with qualified solar technicians for best results.
Frequently Asked Questions (FAQs)
Can solar water pumping inverters work without batteries?
Yes. Most systems run directly from solar panels.
Can the inverter run the pump at night?
Only hybrid systems with grid, generator, or battery backup.
Are solar pumping inverters suitable for boreholes?
Yes. They are ideal for deep borehole submersible pumps.
How long do solar water pumping inverters last?
Typically 8–15 years with proper installation and maintenance.
