ABB Motion, the motors and drives business unit of ABB, has launched the ACQ80 solar drive, a variable speed drive (VSD) system designed to optimize water pumping applications powered by solar energy.

The ACQ80 incorporates integrated Maximum Power Point Tracking (MPPT) logic, ensuring maximized energy extraction from connected photovoltaic (PV) panels. This feature, combined with a wide input voltage range of 225 to 800 VDC, enables continued pump operation even during periods of low sunlight. This expanded operational window translates to greater water volume pumped across diverse operating conditions.

While primarily intended for off-grid applications, the ACQ80 also offers the flexibility of directly accepting alternating current (AC) input from either the local grid or a generator.

The ACQ80 boasts a suite of built-in pumping functionalities, including flow calculation, dry-run protection, pump cleaning capabilities, and various intelligent operating modes. These features work in synergy to streamline the water pumping process while minimizing the need for manual intervention. Additionally, a Fieldbus connection facilitates the integration of the VSD into comprehensive control systems.

The ACQ80 operates effectively at rated current at altitudes up to 1,000 meters, with a 1% reduction for every subsequent 100 meters, reaching a maximum operating altitude of 4,000 meters. The device is further designed to withstand relative humidity ranging from 5% to 95% and ambient temperatures up to 60 degrees Celsius. An optional Bluetooth controller can be incorporated to enhance control in remote locations.
