New inverter designed to optimise solar pumping applications
Motor and drive supplier WEG has announced the launch of its new ADV200-SP drive for solar pumping applications. This cutting-edge variable frequency drive is designed specifically for isolated or hybrid solar-powered water pumping systems, bringing a new level of efficiency and sustainability to the agricultural and industrial sectors.
The ADV200-SP drive is one of WEG’s latest inverter offerings. Developed using WEG’s expertise in industrial drive technology, the new ADV200-SP drive combines the capability of the existing ADV200 inverter and WEG’s extensive experience in solar and pump applications via photovoltaic (PV) panels.
Leveraging the synergy between its inverters and solar technology, WEG has also developed a software application that optimises the operation of solar pump systems.
At the heart of this innovation is the MPPT dynamic search algorithm, developed by WEG engineers. 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 allows for greater efficiency and performance under real-world conditions.
One of the stand-out features of the ADV200-SP Drive is its versatility in accommodating different plant configurations. It seamlessly caters to isolated systems with a single solar source, dual systems alternating between solar and secondary AC sources, and hybrid setups that can also incorporate both sources. A special source manager function integrated into the drive simplifies the management of dual-source systems, ensuring a smooth transition from one source to another while prioritising the use of free solar energy to maintain irrigation continuity.
The ADV200-SP Drive boasts a power range spanning from 1.5 to 400kW, making it suitable for a wide range of plant dimensions. Whether integrated into a small-scale operation or a complex irrigation system, this drive has the power and adaptability to meet a range of needs.
To provide comprehensive support for pump protection and operation, the ADV200-SP incorporates several specialised features within its software. These features include radiation sensor management, auto start and stop functionality, tank level control, dry run protection, flow and pressure loop control, suitability for both distribution and submersible pumps, and even a pump cleaning feature. This comprehensive suite of functions ensures that any pumping system operates smoothly and efficiently.
