Optimized for Solar PV Water Pumping Systems:The ACS380 is ABB’s dedicated drive for solar-powered water pumping, supporting DC bus input (from PV arrays or rectifiers), enabling direct solar-to-pump operation without additional inverters – improving overall system efficiency.

High Efficiency & Maximum Solar Utilization:Built-in advanced MPPT (Maximum Power Point Tracking) algorithm continuously tracks the optimal power output from the PV array, maximizing water yield under varying sunlight conditions.

Wide DC Input Voltage Range:Accepts wide DC input voltage (typically 540–800 V DC), compatible with various PV string configurations, ensuring stable operation across diverse climates and irradiance levels.

Battery-Free Operation, Lower System Cost:Supports direct-coupled operation without batteries, reducing system cost and maintenance complexity – ideal for off-grid applications such as rural water supply, agricultural irrigation, and livestock watering.

Smart Control & Auto Start/Stop:Automatically starts/stops the pump based on sunlight availability; supports feedback control via pressure, level, or flow sensors for intelligent water management and prevention of dry running.

Integrated Pump Protection Functions:Features comprehensive protection including dry-run protection, low-water detection, overcurrent, overvoltage, undervoltage, and overheating – ensuring motor and pump safety and longevity.
