Extracting groundwater from deep aquifers presents unique engineering challenges, particularly in remote regions where the electric grid is absent. For distributors and EPC contractors, selecting a solar borehole pump is a decision that impacts the long-term viability of the water source. High head requirements and long cable runs demand a system that is both hydraulically efficient and electrically protected.
HOBER provides high-performance solar water pumping systems designed for the rigors of deep well extraction. With a focus on the B2B market, we offer complete systems that integrate our industry-leading inversores de bombas solares with specialized submersible hardware.
Deep Well Groundwater Extraction: Overcoming High Head Challenges
| Borehole Parameter | HOBER Specification | Installer Note |
|---|---|---|
| Maximum Head | Up to 500m Lift | Confirm static and dynamic levels first |
| Rango de potencia | 0.75kW – 55kW | Standard AC/DC submersible range |
| Cable Protection | AC Reactor Included | Mandatory for cable runs >100m |
| Protección contra funcionamiento en seco | Sensores de nivel de agua | Protects motor from dry borehole scenarios |
| Hardware Material | Corrosion Resistant | Designed for long-life in deep aquifers |
When the static water level is deep, the solar borehole pump must exert significant pressure to move water to the surface. HOBER systems are engineered to handle heads up to 500m, utilizing both AC and BLDC motor technologies to match the specific needs of the project. For installers, understanding the dynamic water level is critical to preventing dry-run scenarios that can destroy a submersible motor.
- High-Head Performance: Our pumps are designed for vertical lift, ensuring stable flow rates even at extreme depths.
- Dynamic Sizing: We recommend using our sizing tool to ensure the pump power and inverter capacity are perfectly matched to the total dynamic head (TDH).
- Material Integrity: Using high-grade materials for impellers and motor housings ensures resistance to the corrosive or abrasive elements often found in deep groundwater.
Accurate borehole data is the foundation of a reliable solar pumping installation.
Critical Site Parameters: Ensuring Pump and Borehole Compatibility
A successful borehole installation depends on more than just the pump’s power. Distributors must confirm three primary factors before selection: well diameter, well depth, and the dynamic water level. HOBER’s HSPH series inverters provide the intelligence needed to monitor these variables in real-time.
Nuestro hybrid solar pump inverters feature built-in dry-run protection via water level sensors. This prevents the pump from operating when the water level drops below the intake, a common issue in over-extracted aquifers. By providing a complete system—including the PV array, cables, and sensors—HOBER ensures that every component is compatible and protected.
Protecting the Asset: Motor Insulation and Long Cable Management
In deep well applications, the distance between the surface-mounted inverter and the submerged pump can be substantial. Long cables introduce electrical noise and voltage spikes that can degrade motor insulation over time. HOBER addresses this through specialized protective accessories that are often overlooked in cheaper, consumer-grade systems.
- AC Reactor Integration: For cable runs exceeding 100 meters, HOBER provides matched AC reactors. These components suppress dv/dt noise, ensuring the motor operates within its design limits and extending its life by years.
- IP65 Inverter Enclosures: Our large-power inverter cabinets (75kW-500kW) are built to withstand harsh outdoor environments, providing reliable control in any climate.
- PV Configuration: We simplify the engineering by providing exact PV string configurations (typically 1.5x pump power) to ensure consistent performance from dawn until dusk.
Preguntas frecuentes
What information is needed to correctly size a borehole pump?
To ensure a reliable system, you must confirm the well diameter, the total depth of the well, and the dynamic water level (the level the water settles at while the pump is operating). This data determines the total dynamic head required.
How do you protect a submersible motor from burning out?
HOBER systems utilize two primary defenses: water level sensors for dry-run protection and AC reactors to suppress voltage spikes on long cable runs. These prevent motor overheating and insulation breakdown.
Are HOBER borehole pumps compatible with generators?
Yes. Our Hybrid AC/DC systems allow you to blend power from solar panels and a backup generator. This ensures you can continue extracting water even during periods of low sunlight or high demand.
