The significant reduction in the pricing of photovoltaic panels, together with the upward trend in the cost of fossil fuels and grid electricity, has led to a boom in profitable solar pumping systems.
Developed using WEG’s expertise in industrial drive technology and extensive experience in solar and pump applications via photovoltaic (PV) panels, the ADV200-SP solar pump drive converts energy received via a PV array into electrical power capable of operating a standard three-phase electric pump.
At the heart of this innovation is the MPPT dynamic search algorithm. This algorithm ensures that the ADV200-SP Drive continuously adapts to varying irradiation and temperature conditions, maximising system load at maximum output power. This adaptability maximises efficiency and performance under real-world conditions.
The ADV200-SP Drive offers remarkable versatility for various plant configurations. It effortlessly adjusts to isolated systems powered only by a PV array or dual supply systems that switch automatically between solar energy and an additional AC source, such as a grid connection or generator. This adaptability can eliminate the expensive requirement of installing a grid connection in remote locations or reduce the dependence on fossil fuel-powered generators.
If operation must be guaranteed even under low irradiance conditions, then the ability to have a dual supply, including a backup power source such as a grid supply or a genset, adds a level of redundancy and allows for longer operating times under low irradiance conditions. The ADV200-SP has the intelligence to supervise both supplies, ensuring a seamless transition from one source to the other. The Solar Pump drive can even operate from the PV array and the backup source simultaneously, always preferring to harness the free power of the sun, minimising the costs associated with the import of electricity or fuel for local generation.
The solar pump drive boasts an extensive power range from 1.5 to 400 kilowatts (kW), making it suitable for a wide array of applications. In fact, the ADV200-SP allows the parallel connection of power modules, increasing the maximum conceivable power limit to 1.8 megawatts (MW). With control features such as dual PID loops for pressure, flow, or tank level control, and a real-time clock for auto start and stop, the ADV200-SP can run independently or equally well at home, being integrated into other control platforms.
The ADV200-SP also offers the convenience of advanced pump protection features, such as dry pump protection, burst pipe protection, and de-ragging. These features aim to maximise plant uptime while harnessing the maximum potential energy from the sun. The ADV200-SP can handle applications such as flood irrigation, pivot irrigation, remote water supply, cattle drinking fountains, water treatment, and fish farming.
The ADV200-SP, together with the power of the sun, is the ultimate energy-efficient pump solution.
