A simpler system solar pumping system
SunWave is a battery-free, island solar pumping system: fewer components, lower installation cost, dependable performance off-grid.
Solar pumping is one of the most effective ways to bring water to arid and remote areas, turning abundant sunlight into energy without a grid connection or fossil fuel. The barrier has always been the upfront cost – panels and batteries put the technology out of reach in exactly the places that need it.
SunWave is built around that constraint. The motor adapts to the pump rather than forcing a fixed setup, which keeps the number of panels to a minimum. By converting solar radiation into direct pumping energy, it ensures full autonomy from electrical infrastructure, allowing water pumping without the need of a battery bank.
This integrated approach reduces system complexity and enables reliable water pumping in locations where conventional systems are not technically or economically viable, particularly in rural and agricultural areas across regions such as Sub-Saharan Africa and the Middle East.
Sunwave is engineed by Mac3 and Umbra Pompe, two Italian family companies and combines a Sub Solar pump with the Epower Solar inverter, designed to work together as one system rather than separate components.
Frequently Asked Question about Sunwave solar pumping system for off-grid water access
SunWave operates completely off-grid:
- no grid connection
- no batteries
- no external energy storage
The system runs directly through solar irradiation. When sunlight is available, water is pumped.
The system is designed for simplicity, reducing components while maintaining reliability in real field conditions. It features:
- Monoblock pump design
- Three-phase asynchronous motor (V.80 / V.110 / V.230), allowing voltage optimization based on pump power, reducing the number of solar panels required
- Operation with minimal photovoltaic sizing
- Direct solar-to-pump operation
- No DC/AC switching or battery systems
SunWave is designed for a wide range of water management applications, including:
- Boreholes and deep wells — reliable extraction from depths up to 60m.
- Irrigation systems – daytime pumping into storage for crops and plantations.
- Water tanks and storage systems – filling accumulation systems,
- Livestock, rural and agricultural water supply.
SunWave operates directly on solar irradiation: when there is sun, the pump runs. For its typical applications – filling tanks and reservoirs, irrigation, livestock and borehole supply – pumping into tanks during daylight covers demand without the cost and replacement cycle of a battery bank. It’s the architecture suited to off-grid sites with contained water requirements, minimizing up-front installation costs.
Island water pumping systems rely on off-grid, renewable energy setups to bypass unreliable power grids. Solar pumping systems utilize submersible or surface pumps paired with solar arrays and inverters to draw water from wells or reservoirs.
SunWave is designed for remote, off-grid regions where access to water and energy infrastructure is limited.
Solar pumping with fewer panels
SunWave provides a simple and reliable pumping solution in environments where traditional systems are not economically or technically feasible, ensuring water access with a balanced and scalable setup. The system is optimized to reduce energy demand, allowing a lower number of solar panels compared to conventional solar pumping solutions.<br />
Reduced system complexity
The system architecture is built without batteries or external energy storage, enabling direct solar-to-pumping operation. This simplifies installation and reduces maintenance requirements, making it suitable for remote and rural applications.
A kit designed for water pumping in off-grid areas
The SunWave kit includes an Umbra Pompe pump and a Mac3 inverter, engineered to work together. Dependable performance across boreholes, wells, tanks and irrigation.
SunWave is designed for remote, off-grid regions where access to water and energy infrastructure is limited.
