A Simple, Efficient System Designed for Reliable Water Delivery
How A Solar Pump System Works
A solar pump inverter converts DC energy from solar panels into stable AC power to run the water pump. With dynamic VI-MPPT, it continuously tracks the best power point, adjusts pump speed based on sunlight, and delivers smooth, efficient water flow throughout the day. When connected to water-level sensors, the system can automatically stop if the well is low or the tank is full, ensuring safe and fully automatic water management.
1
Solar Panel Array – Captures Sunlight
High-efficiency PV modules convert sunlight into DC electricity.
The size of the array is selected based on pump power, required water volume, and sunlight conditions.
2
Solar Pump Inverter – Core Power Conversion & MPPT Control
The inverter receives DC power from the PV array and performs three key functions:
a. VI-MPPT Tracking
Continuously finds the optimal operating point to extract maximum solar energy throughout the day—even during shading or fast weather changes.
b. DC to AC Conversion
Converts solar DC power into stable AC output to drive submersible, centrifugal, or surface pumps.
c. Intelligent Pump Protection
Manages motor acceleration, reduces water hammer, and protects against dry-run, overload, overheat, and voltage fluctuations.
3
AC Output to Pump – Drives Water Lifting
The inverter supplies AC power to the pump and adjusts its frequency based on available solar energy.
Higher sunlight → higher speed and flow;
Lower sunlight → lower speed but continuous operation instead of shutdown.
This ensures maximum liters-per-hour output and stable daily water supply.
4
Water Level Sensors (Optional) – Automated System Control
Two optional sensors can be connected:
Well level sensor: stops the pump when water is too low (dry-run protection).
Tank level sensor: stops pumping when the tank is full and restarts when water drops.
This enables unattended, fully automatic water management—essential for agriculture and community water systems.
5
Water Storage Tank / Irrigation Network
Water is pumped into:
Storage tanks
Irrigation channels
Drip or sprinkler systems
Community water pipelines
Once stored, the water can be supplied even at night or during cloudy weather, making solar pumping a complete off-grid solution.

Yes. The inverter adjusts motor frequency according to available PV power using VI-MPPT.
This ensures the pump continues running at a lower speed rather than shutting down, maintaining water supply as long as minimal solar input is available.
All ZINREY inverters include dry-run protection, overheat protection, overvoltage & undervoltage protection, overload & short-circuit protection, surge protection, and phase-loss protection.
These protections ensure pump safety and long-term reliability in harsh environments.
Yes. We provide logo printing, metal housing customization, packaging design, label customization, cable options, manual localization, and project-specific parameter adjustments.
