Specifications

The Hope65-SP solar water pump VFD is designed for high-efficiency motor control in solar and hybrid pumping systems. With wide voltage compatibility, advanced MPPT technology, and multiple protection functions, this inverter ensures stable performance, maximum solar energy utilization, and long equipment lifespan in demanding field environments.

Key Parameter Ranges & Performance Advantages

The Hope65-SP series covers a power range of 0.75kW to 55kW, enabling flexible configuration for small agricultural irrigation pumps up to large municipal or industrial water supply systems, helping users match motor size precisely and reduce system cost. 

It supports 220V class (0.75–5.5kW) and 380V class (0.75–55kW), allowing easy integration into existing single-phase or three-phase electrical infrastructures, minimizing retrofit cost and installation complexity.
The drive operates with wide DC input ranges (up to 450Vdc for 220V class and 900Vdc for 380V class), ensuring stable operation even under fluctuating solar irradiation conditions and maximizing system uptime. 

The system supports AC input tolerance of -15% to +10% voltage fluctuation and 47–63Hz frequency range, guaranteeing stable operation in unstable grid or generator environments. 
With output frequency range of 0.1–500Hz, the drive enables precise motor speed control, improving pump efficiency and extending motor service life. 
The unit delivers overload capacity up to 150% rated current for 60 seconds (heavy-duty mode), ensuring reliable operation during sudden load increases such as pump startup or pressure fluctuation. 
The carrier frequency adjustable from 0.8–8kHz reduces motor noise and optimizes thermal performance, improving overall system stability. 
The inverter operates reliably in -10°C to +50°C working temperature and 20–90% humidity environments, making it suitable for harsh outdoor agricultural and industrial installations. 

Intelligent Control & Communication Advantages

Built-in RS485 communication with Modbus RTU protocol enables seamless integration into SCADA, remote monitoring, and automated water management systems, improving operational efficiency and reducing labor cost. 
Support for VF control and sensorless vector control provides stable torque output and precise speed regulation, ensuring high pumping efficiency under variable load conditions.
Integrated MPPT solar optimization algorithm continuously tracks the maximum power point, allowing pumps to operate at optimal efficiency throughout the day and significantly improving water output. 

Safety & Reliability Features
Multiple built-in protections including over-voltage, over-current, overheating, phase loss, and motor overload protection ensure safe long-term operation and reduce maintenance risk. 
The drive includes automatic voltage regulation (AVR) to stabilize motor operation during input power fluctuations, protecting connected equipment. 
Structural & Installation Benefits
The drive features IP20 protection and forced air cooling, ensuring reliable thermal management and long component lifetime under continuous operation. 
The removable keypad design enables convenient parameter setting, monitoring, and maintenance, reducing on-site commissioning time.
