SV20 Series Solar Pump Inverter
The full-feature KEVAN solar pumping platform: grid-adaptive, light-sensing, app-controlled and able to swap between DC and AC in under 10 milliseconds.
What the SV20 Is For
The SV20 is KEVAN's flagship solar water pump inverter. It reaches up to 96% energy conversion efficiency with peak efficiency quoted at 98.7%, switches between AC and DC sources in under 10ms, detects light intensity to change source automatically, and carries CE certification for export markets.
Key Benefits
- Energy conversion efficiency up to 96%, with the highest efficiency quoted at 98.7%, so more of the array output reaches the water.
- Unattended operation - the system works at sunrise and stops at sunset and is designed for years of maintenance-free service.
- One-time investment with long-term returns, and eligibility for government subsidies in many regions.
- Clean energy operation with no fuel, no pollution and zero carbon dioxide emissions in use.
Application Scenarios and Buyers
Irrigation District Operators
Central irrigation systems where several pumps must run unattended and be supervised from one place.
Agricultural Projects and Co-operatives
Large-area irrigation where every percentage point of conversion efficiency shows up in yield per panel.
Rural and Municipal Water Supply
Systems that cannot tolerate a gap in supply when cloud passes over the array.
Industrial Process Sites
Cable, machine tool, metal products, petrochemical, natural gas, lifting, pulping and papermaking, textile, printing and dyeing and ceramics plants.
Export Distributors and System Integrators
Partners who need CE certification and grid-adaptive behaviour for varied national grid rules.
What Goes Wrong Without It
Cloud Cover Interrupts Pumping
AC/DC switching time under 10ms means the pump keeps turning when the source changes, instead of stopping and restarting.
Grid Connection Rules Differ by Country
Smart grid-adaptive technology is designed to meet varied grid access requirements so the same product ships to different markets.
Somebody Has to Drive Out and Check It
A GPRS module gives remote control from a mobile app, so system status is visible from anywhere.
Manual Switching Wastes Daylight
Automatic light detection identifies light intensity and switches AC and DC input without an operator.
Electrical Noise on Long Cable Runs
Strong EMC anti-interference performance and redundant protection design keep the drive stable on long field cabling.
Design Details That Matter on Site
MPPT Maximum Power Output
Maximum photovoltaic utilisation with multiple protection functions.
Free Switching Under 10ms
AC/DC switching time is less than 10ms, so pumping is uninterrupted.
Grid Adaptive Intelligence
Smart grid-adaptive technology meets various grid access requirements worldwide.
Automatic Light Detection
Identifies light intensity and automatically switches between AC and DC input.
GPRS Remote Control
GPRS module supports remote control from a mobile app.
Broad Motor Support
Drives S.R.M., P.M.S.M. and A.M. motors, with single-phase and three-phase pump compatibility.

How It Compares With the Rest of the Range
How the SV20 sits against the other KEVAN series:
| Against SV13 | The SV13 is the miniaturised, cost-focused solar pump drive. The SV20 adds grid-adaptive control, automatic light detection, sub-10ms source switching and the higher quoted efficiency figures. |
|---|---|
| Against KV500 | The KV500 solves the single-phase 220V in, three-phase 380V out problem. The SV20 is the full solar pumping platform for larger, supervised systems. |
| Against KV100 / KV600 | Those are grid-powered industrial drives without MPPT, PV input or hybrid switching. |
Use Guide
- Confirm pump type and phase - the SV20 supports single-phase and three-phase pumps and S.R.M., PMSM and asynchronous motors.
- Plan the array around the pump duty point so MPPT has enough headroom through the day.
- Order the GPRS module with the drive if the site is to be supervised remotely.
- Configure hybrid mode and light detection thresholds at commissioning rather than leaving defaults.
- Use the LED interface for setup on site; one-key operation covers routine starts and stops.
- Keep CE documentation with the shipment for customs and project sign-off in export markets.
