Providing smart driving for sustainable water sources — Streamlined design, efficiently controlling every drop of energy.
Product Description:
MPPT Solar Water Pump Inverter (PCB Board-Level Solution)
The core driver board designed specifically for photovoltaic (PV) water pump systems, adopting a high-efficiency MPPT algorithm and modular design, can be directly integrated into custom systems by customers. It supports DC solar input, AC mains input, and hybrid power mode, compatible with three-phase/single-phase pump drives. It is suitable for off-grid/on-grid scenarios such as agricultural irrigation, livestock water supply, remote village drinking water, and sewage treatment. The board has rich interfaces, providing flexible peripheral expansion capabilities, making it the low-cost, high-reliability control core for solar water pumps.
Key Features
Modular Integration Design
– Integrated Single Board Structure: Control board, power module, communication interface integrated layout for simplified installation and maintenance.
– Independent Control Board Support: Control boards can be purchased and replaced separately, reducing maintenance costs (model 5G814).
Multiple Input Compatibility
– Solar DC Input: Supports a wide voltage range of 80V–900VDC, suitable for various PV panel arrays.
– Hybrid Power Mode: Optional AC mains input (220V/380V), automatically switches to grid power in the absence of sunlight.
– Polarity Self-Adaption: No need to distinguish positive and negative when connecting solar panels to R/T terminals (P/N terminals must strictly differentiate polarity).
Efficient MPPT Tracking
– Tracking Efficiency > 99.6%: Quickly responds to changes in sunlight to maximize solar power extraction.
– Dual Algorithm Modes:
Mode 1 (PE-00=1): Prioritizes high efficiency with dynamic CVT gain adjustment (PE-04/PE-05).
Mode 2 (PE-00=2): Prioritizes high stability with optimized search intervals and filtering (PE-12/PE-13).
Industrial-Grade Protection Functions
– Onboard Temperature Monitoring: Detect heat sink temperature + over-temperature protection (model 5G814)
– Pump-Specific Protections:
Dry run protection (PE-22/PE-48), low-frequency protection (PE-19), water shortage detection (PE-31).
– Lightning Protection, Phase Short Circuit Protection, Input/Output Short Circuit Protection.
– Fault Self-Diagnosis: Records current/voltage/frequency states of the last three faults (P9 group parameters).
Rich Expansion Interfaces
– Control Terminals: 3 DI digital inputs + 1 AI analog input + 1 relay output.
– Communication Interface: RS485 standard port, supports Modbus protocol.
– Reserved Expansion: 24V fan power interface, external sensor interfaces (water level/flow).
Intelligent Operation and Maintenance Support
– Automatic Sleep/Wake-Up: Start and stop based on sunlight intensity (PE-16/PE-17), saving energy and reducing consumption.
– PQ Flow Calculation: Real-time monitoring of water output flow via power-flow curve (U0-13).
– Data Statistics: Cumulative power generation (U0-18/U0-19), daily water supply (U0-14) records.
Applicable Scenarios
– Pump Types: Three-phase asynchronous motor (IM), permanent magnet synchronous motor (PMSM), single-phase AC water pump.
– Power Range: 0.3kW–100kW (requires an external cooling system).
– Typical Applications: Deep well submersible pumps, centrifugal pumps, booster pumps, suitable for harsh environments such as desert management, pond management, forest irrigation.
Note: PCB board-level solution and does not include heat sinks, enclosures, fans, or other peripheral components. Customers need to customize cooling and structural design according to system requirements. For complete technical parameters, please refer to the operation manual PE/P parameter group.
