For distributors and solar EPCs, the reliability of a solar pumping project hinges on the core control unit: the inversor de bomba solar. In high-demand agricultural and municipal water supply applications, system downtime is not just a technical failure—it represents lost ROI and increased maintenance overhead for the contractor. HOBER, a specialized factory with 16 years of expertise, delivers the HSPH Series to solve these challenges with industrial-grade engineering.
As a leading China-based manufacturer, HOBER operates five automated production lines under ISO9001 quality management, ensuring that every inversor de bomba solar meets the rigorous standards required for global distribution and large-scale tenders.
Scalable Architecture: From Small Farms to 500kW Industrial Plants
| Parameter | Specification | Nota |
|---|---|---|
| Rango de potencia | 0.75kW – 500kW | Covers residential to industrial projects |
| Input Voltage (L-Series) | 220V/240V Single Phase | Optimized for light commercial/residential |
| Input Voltage (H-Series) | 380V/400V/440V Three Phase | For high-flow irrigation and deep extraction |
| Protection Rating | IP65 (Cabinets) / IP20 (Standard) | Cabinets available for 75kW-500kW models |
| Sizing Ratio | Inverter ≥ Pump Power | Optimal range 1.0x to 1.2x pump power |
The HSPH Series is designed with a wide power range to accommodate diverse project scales. Whether you are supplying a small village water system or a massive irrigation scheme, HOBER provides a pre-matched solution that eliminates the guesswork of controller selection.
- HSPH-L Series: Optimized for single-phase 220V/240V AC pumps, providing a cost-effective solution for residential or light commercial water transfer.
- HSPH-H Series: Built for heavy-duty three-phase 380V/400V/440V pumps, supporting high-flow irrigation and deep-well extraction.
- HSPH-B (Booster) Models: Integrated step-up functionality for low-voltage PV strings, reducing the number of panels required for the startup voltage.
- Cabinet Systems: For high-capacity projects (75kW to 500kW), we offer specialized IP65-rated inverter cabinets designed for outdoor durability in harsh environments.
HOBER HSPH Series solar pump inverters are engineered for 24/7 performance in remote off-grid locations.
Built-in MPPT and Advanced Control Logic
Maximizing water output from limited solar irradiance is the primary goal of any inversor de bomba solar. The HSPH series features an advanced Maximum Power Point Tracking (MPPT) algorithm with 99% efficiency, ensuring the pump starts earlier in the morning and stops later in the evening.
Beyond simple motor control, HOBER inverters integrate comprehensive protection features including dry-run protection via water level sensors, over-voltage protection, and short-circuit shielding. For EPCs, this means fewer field failures and zero-risk handovers to the end-user. For projects with long cable runs exceeding 100 meters, HOBER provides pre-matched AC reactors to suppress dv/dt noise and protect motor insulation.
Technical Sizing Rules for High-Efficiency Pumping
Correct sizing is critical for system longevity. To help our partners reduce engineering risk, HOBER provides a free solar pump sizing inverter selection tool. When selecting an inverter, follow these mandatory factory guidelines:
- Power Ratio: The inverter power must always be greater than or equal to the pump power. We recommend keeping the inverter power below 1.2x the pump power for optimal thermal performance.
- Voltage Matching: Match the pump phase and voltage to the specific series (L for single-phase, H for three-phase).
- PV Configuration: Total PV power should ideally be 1.5x the pump power to cover system losses and irradiance variations.
Preguntas frecuentes
Can I use a single-phase inverter for a three-phase pump?
No. You must match the phase of the inverter to the pump motor. Use the HSPH-L series for single-phase 220/240V pumps and the HSPH-H series for three-phase 380/400/440V pumps.
What is the “B” suffix in HOBER inverters?
The “B” suffix denotes a “Booster” model. These inverters include integrated step-up functionality, which allows the system to reach the required startup voltage with fewer PV panels connected in series.
How do I protect the motor when the cable is very long?
For cable runs exceeding 100 meters, HOBER recommends and provides pre-matched output AC reactors. These components suppress dv/dt noise and voltage spikes to protect the motor insulation from premature degradation.
