Q1 What is an AC solar pumping system?
It is a renewable energy system that converts solar energy via PV modules into DC power, which is then converted into AC power by a solar inverter to drive standard 3-phase AC water pumps.

It is a renewable energy system that converts solar energy via PV modules into DC power, which is then converted into AC power by a solar inverter to drive standard 3-phase AC water pumps.
MPPT (Maximum Power Point Tracking) continuously adjusts the output frequency according to real-time sunlight intensity, ensuring the pump operates at maximum efficiency even during cloudy days.
No, our system is designed to dispense with energy storage batteries. It stores water in tanks or reservoirs instead of electricity, drastically reducing maintenance and initial costs.
Yes, the system operates automatically and intelligently. It starts when sunlight is sufficient and adjusts its speed or shuts down based on irradiation levels, lowering labor costs.
Depending on your specific requirements, the system is highly compatible with submersible pumps, surface pumps, and swimming pool pumps driven by three-phase AC induction motors. This includes centrifugal pumps, axial flow pumps, mixed flow pumps, and deep well pumps, all of which can be seamlessly integrated.
Our standard product line covers a wide power range from 0.75 kW up to 110 kW. For larger-scale or specialized projects, systems with higher power capacities can be fully customized and deployed to meet your specific requirements.
It optimizes a single pump setup to minimize the required PV modules while fully meeting the local head and water capacity requirements based on sunlight hours.
In large-scale projects, multiple pumps share solar arrays. The system dynamically switches solar power to fewer pumps during weak sunlight to maintain high efficiency, extends operating hours and maximizes solar energy utilization.
Sizing depends on your required daily water volume, total dynamic head (well depth + lift height), and your geographic location's solar irradiation. Contact us for a customized solution.
Yes. Solartech solar pumping inverters are highly compatible and can drive standard 3-phase AC motors, allowing you to upgrade your traditional system easily.
Absolutely. The system can connect directly to modern irrigation systems, delivering steady water supply for crop fields and orchards.
Yes, it is widely applied in remote areas and islands for village water supply, pumping groundwater into storage tanks for daily use.
It is ideal for harsh environments, providing reliable water for afforestation in desert control and watering livestock in remote pastures without grid access.
Yes, our versatile systems can be configured for water conservancy projects, fountain waterscapes, and wastewater treatment engineering.
Yes, absolutely. Solartech AC solar pumping systems are specifically engineered for remote, off-grid, and harsh environments. By dispensing with energy storage batteries, the system eliminates battery-related maintenance and temperature-sensitivity issues, making it highly reliable for desert control, remote livestock farming, island water supply, and agricultural irrigation in regions with unstable or non-existent power grids. It utilizes an eco-friendly "water storage instead of electricity storage" approach to ensure a dependable water supply anywhere the sun shines.
Yes. For large-scale water demands, our Multi-pumps System Optimization provides a highly flexible and powerful solution. Several pumps can be driven either by one high-power inverter or multiple matching inverters. Through smart switching of solar arrays, the system runs all pumps in MPPT mode under peak sunlight, and intensively concentrates solar power to the remaining active pumps during weak irradiation. This ensures maximum water yield and constant operation for massive agricultural or industrial water conservancy projects.
Absolutely. While the system operates entirely on zero-cost solar energy during sunny periods, it features a highly reliable advanced backup power function for critical applications requiring day-and-night water supply. It can be seamlessly integrated with a hybrid power source, automatically switching to the local utility grid or an external diesel generator during the night or prolonged overcast periods, ensuring uninterrupted water delivery.
The system is engineered with an intelligent adjustable speed governing range that matches the dynamic requirements of precision drip or sprinkler irrigation. Furthermore, because it is fully compatible with induction motors used in standard swimming pool pumps and surface pumps, it can be perfectly applied to remote resort swimming pool filtration, aquaculture pond aeration, and automated waterscape fountain control, maximizing energy efficiency across diverse ecological and commercial scenarios.
The pump's rotational speed will decrease in weak sunlight. If irradiation drops below the threshold where output capacity becomes zero, the system will temporarily pause and restart once sunlight returns.
Solartech provides reliable product warranties. Solar panels typically last over 25 years, and inverters last over 5-10 years with proper maintenance.
