Solar Pump Inverter

Power your water systems sustainably with the CDADA Solar Pump Inverter—a smart, off-grid-ready solution designed specifically for solar-powered water pumping applications in agriculture, livestock, irrigation, and remote water supply.

Unlike standard PV inverters, this CDADA Solar Pump Inverter integrates high-efficiency MPPT (Maximum Power Point Tracking) directly with a 3-phase AC motor drive, enabling direct conversion of solar DC power into variable-frequency AC to drive submersible, surface, or centrifugal pumps—without requiring batteries or grid connection.

Available in power ratings including 15kW (and scalable from 1.5kW to 30kW+), it supports 3-phase induction motors and features adaptive V/F and vector control for smooth start-up, energy optimization, and stable operation under fluctuating sunlight. Built-in protections—including dry-run detection, over/under-voltage, overcurrent, short-circuit, and motor stall prevention—ensure long-term reliability in harsh rural environments.

With optional IP65 enclosure, RS485/Modbus communication, and mobile monitoring support, the CDADA inverter delivers autonomous, low-maintenance water access powered purely by the sun—ideal for farms, villages, desert wells, and eco-resorts.

Frequently Asked Questions

Q1: Does it need a battery or grid connection?

A1: No. CDADA Solar Pump Inverters operate 100% off-grid, drawing power directly from solar panels. They start at sunrise and stop at sunset—no external power source required.

Q2: Can it work on cloudy days?

A2: Yes—with reduced output. The MPPT algorithm continuously adjusts to extract maximum available power, even under low-light conditions. Pump speed slows but continues to deliver water.

Q3: How does dry-run protection work?

A3: The inverter monitors motor load or current signature. If it detects abnormal low load (indicating no water), it shuts down the pump and retries after a set interval—preventing damage.

Q4: Can I use it with an existing AC pump?

A4: Yes—as long as the pump is 3-phase induction type and matches the inverter’s voltage and power rating (e.g., 15kW inverter → ≤15kW pump). Single-phase pumps require a different model.

Q5: Why choose CDADA over other solar pump brands?

A5: CDADA offers:

● Integrated MPPT + VFD in one unit (no extra controllers)

● Proven reliability in >50 countries

● Customizable communication options (Modbus, IoT)

● Local technical support & fast spare parts

● Best value for mid-to-high-power (5–30kW) applications
