LMVF-PV Series VFD Solar Inverter Water Pump 0.75kW~22kW
Built-in high-precision photovoltaic array maximum power point tracking MPPT algorithm ensures that the solar power tracking efficiency can reach more than 99%
Achieve full-time work. It can work from the sun up to the sun down, which greatly increases the effective working time of the photovoltaic water pump in a day.
By adding an external switching kit, the inverter can realize automatic switching between photovoltaic input and grid input, thereby achieving 24-hour continuous water supply demand.
The product adopts space voltage vector control technology and uses DSP control system to enhance the reliability and stability of the product.
Supports two control modes: V/F control, sensorless vector control (SVC)
Adapt to grid voltage range 200V ~ 440V
MPPT Maximum Power Point Tracking: Real-time tracking and locking of the optimal operating point of photovoltaic panels, improving power generation efficiency by approximately 10%–20%.
Intelligent speed regulation: Automatically adjust the water pump speed according to the light intensity, fast pumping in strong light, slow pumping in weak light, and sleeping in no light to avoid frequent starts and stops.
System protection: built-in overvoltage, undervoltage, overcurrent, phase loss, dry running, overheating, water level protection, etc. to extend the life of the equipment.
Optional mains bypass: Some models support automatic switching between photovoltaic and mains power to ensure continuous water supply.
Main advantages
Off-grid independent operation: No need for power grid, suitable for irrigation in remote mountainous areas, pastures, and deserts.
High efficiency and energy saving: MPPT + variable frequency speed regulation, the overall system efficiency is increased by 15%–20%.
Unattended: Automatically starts at sunrise and stops automatically at sunset, without manual intervention.
Green and environmentally friendly: zero fuel, zero emissions, reducing operation and maintenance and carbon emission costs.
Longer life: soft start, low load operation, reducing mechanical wear of the water pump.
