Our 220v Solar VFD Inverter for Well Pump extends beyond agriculture to industrial and commercial water handling.
It can power pumps for cooling tower circulation, dust suppression systems, vehicle wash stations, and tank filling in factories, mines, or construction sites where grid power is unreliable or costly.
The drive supports hybrid solar‑diesel or solar‑grid input for 24/7 operation.
Built‑in protections against phase loss and overload ensure durability in harsh industrial environments. Examples: mine dewatering, quarry dust control, concrete batching plant water supply, and car wash water recycling. By using solar energy, companies reduce operational costs and carbon footprint.
● Data logging – records daily energy yield, water volume, pump runtime, and fault events.
● Real-time display – LCD keypad shows solar voltage/current, pump frequency, flow rate, and cumulative water output.
● RS485 Modbus RTU – standard port for connection to PLC, SCADA, or data loggers.
● Optional GPRS/4G/WiFi modules – enables remote monitoring via smartphone or cloud platform. Receive alarms for dry-run, over-temperature, or pump fault via SMS or app.
● Predictive maintenance – tracks motor current and vibration (with optional sensor) to warn of bearing wear or impeller blockage before failure occurs.
With remote access, operators can adjust parameters, restart the pump, or schedule cleaning cycles without traveling to the site, reducing operational costs and downtime.
Q1: How much water will my pump deliver per day with this 220v Solar VFD Inverter for Well Pump?
A: Water output depends on solar irradiation, panel size, pump efficiency, and head. A rule of thumb: for every 1kW of solar panels, a typical pump delivers 3‑5 m³/day per 10m head. Use CSIVEI’s online solar pumping calculator with your site data for accurate estimates.
Q2: Does the drive have an energy saving mode beyond MPPT?
A: Yes. The “Auto Energy Optimization” (AEO) feature reduces motor voltage when pump load is light (e.g., low flow demand), cutting energy use by 10‑20% without affecting output. Enable parameter P.52 = 1.
Q3: Can I use smaller solar panels if I add a battery?
A: Yes. With battery storage, you can run the pump for more hours using a smaller array, because surplus solar is stored during peak sun and used later. However, battery cost may outweigh panel savings. CSIVEI offers a hybrid sizing tool.
Q4: How does the drive perform in partial shading conditions?
A: The MPPT algorithm includes “global scan” mode (parameter P.91 = 1) that periodically sweeps the entire I‑V curve to find the true maximum power point, avoiding local peaks caused by shading. This can recover 10‑30% of lost power compared to standard MPPT.
Q5: What is the maximum pump speed this drive can output?
A: The drive outputs 0‑400Hz (default 0‑50/60Hz). For standard pumps, do not exceed motor nameplate frequency (usually 50/60Hz). For high‑speed pumps, you can set up to 400Hz, but ensure the pump and motor are rated for that speed.
An environmental NGO in the Sahel region planted 50,000 trees to combat desertification. A CSIVEI solar pump VFD with a 220v Solar VFD Inverter for Well Pump powered a deep‑well pump to irrigate tree seedlings.
85% seedling survival rate (vs. 40% without irrigation).
Solar operation eliminated need for fuel convoys in remote area.
Automatic low‑water shutdown protects pump during dry seasons.
System has run for 4 years with only one fan replacement.
The project has been replicated in three neighboring villages.
