Frequency controllers for solar pumps from ABB solve the challenges of providing water even in remote locations that do not have access to the power grid. The drive uses photovoltaic panels as a source of energy to operate the water pumps. From dawn to dusk, the drive operates without energy costs in an easy and safe way, with minimal CO2 emissions.
Solar photovoltaic systems for water pumping are becoming increasingly important around the world. They play a crucial role in reducing CO2 emissions and can work in areas that are poorly covered by the power grid, where a reliable water supply is essential to meet the needs of agricultural land irrigation, water livestock and provide drinking water.
ABB’s new generation ACQ80 solar pump inverters are designed to meet this need by enabling efficient operation of solar water pumping systems, with a low carbon footprint, using the clean energy of the sun. Therefore, compared to pumping systems powered by diesel generators, ACQ80 frequency controller for solar pumps is an ecological product, with a long life and low maintenance costs, considering that it works on solar energy.
IN FOCUS:
A key feature of the ACQ80 frequency controller is the built-in Maximum Power Point Tracking (MPPT) technology, combined with a wide input voltage range from 225 to 800 VDC, as well as PID control to achieve the desired water pressure in the pumping system during irrigation. This allows the controller to run the pump motor even if the output power of the solar panels drops during periods of low sunlight. Such a wide range of permissible operating conditions is a significant improvement compared to conventional frequency regulators and enables the maximum amount of water to be pumped at all times.
Although the ACQ80 will mainly be used in off-grid applications, where it converts the direct current (DC) from the solar panels into the alternating current (AC) needed to operate the pump, this frequency regulator also has the ability to be supplied with alternating voltage (AC). This allows it to be connected to the local power grid or generator, thus ensuring continuity of operation of the pumping system during the night or during periods of low sunlight by combining supply from direct and alternating current sources.
ACQ80 offers additional integrated functionalities required in pumping systems, such as flow calculation, dry run protection, pump cleaning and optimization of the water pumping process, thus reducing human interventions to a minimum. It is also possible to connect via fieldbus communication protocols and integrate the frequency regulator into control systems. The ACQ80 is compatible with induction motors as well as highly efficient synchronous permanent magnet reluctance motors (SynRMs) in both submersible and surface pump types.
ACQ80 was awarded as an efficient solution by the Solar Impulse Foundation (Solar Impulse Efficient Solution), which confirms the profitability of the product and the application of clean energy. This label is awarded to products, services and/or processes that combine credible environmental and economic performance, while at the same time performing better than traditional options in their market.
