【Project introduction】
In Lahore, Pakistan’s core agricultural region, a village has upgraded its irrigation system with a V&T SP300 photovoltaic water pump system. Compared with traditional diesel power systems, this solution achieves:
■ Annual operating costs are reduced by 65%
■ System life cycle maintenance costs are reduced by 50%
■ Very low maintenance costs, global unmanned automatic operation
【V&T Project products】
■ Pump:7.5kW / 3 phase 380V / 50Hz / 13.4A
■ Inverter: SP300-4T-7P5G, 7.5kW, 17A
■ Solar Panel: POLY 360W/pc, 24 pcs total (12 pcs in series with 2 parallel)

2. Wide compatibility
Equipment compatibility: Suits for most 3 phase AC pumps and AC PMSM high efficiency pumps
Power supply compatibility: Compatible with AC grid and SP power supply input at the same time
3. Intelligent control and automation
Fully automatic operation: Digital control for fully automatic operation, data storage and protective functions
Energy saving mode: Built in automatic sleep-wake up function
Precise control: Input VOC auto-detect function, Clock relay card for timing stop and stop control
4. All-round protection mechanism
Dry run (under load) protection, Motor maximum current protection, Low input power protection, Lowest stop frequency protection, Strong lightning protection
5. Environmental adaptability and monitoring
Wide temperature adaptability range: Ambient temperature for using: -10 to +50°C
Intelligent detection: Low water probe sensor, and water level control function, The PQ (power/flow) performance curve enables calculating the flow output from the pump
6. Flexible expansion function
LCD keypad as optional
Solar water pumps can be used as drinking water for people and livestock or irrigation water for other crops in pastoral areas, grasslands and other areas with power shortage or no electricity. They can also be used for water supply facilities in gardens, villas, grasslands and camping sites. V&T photovoltaic water pump solutions are particularly suitable for the Indus Plain area with an average daily irradiation of more than 5kWh/m². Through modular design, the system can be flexibly expanded according to the scale of farmland, providing clean power options for Pakistan's 45 million hectares of irrigated land. The SP300 series photovoltaic water pump dedicated inverter system has become the preferred solution for solving water problems in remote areas due to its advantages such as easy installation, no need for manual supervision, low cost and zero carbon emissions. At present, V&T's photovoltaic water pump intelligent solution has been widely used in more than 30 countries including Pakistan, Syria and Egypt, providing stable and reliable water supply services to local residents.
