ACS380-040S-045A-4 ABB Frequency Converter Plc Programming Controller Module

Designed Specifically for Solar Water Pumping Systems:The ACS380 is ABB’s dedicated drive for solar-powered water pumping, supporting DC bus input (540–800 V DC) from PV arrays or rectifiers – enabling direct solar-to-pump operation without batteries or grid-tied inverters, ensuring high efficiency and system simplicity.

Built-in High-Precision MPPT for Maximum Energy Harvest:Features advanced MPPT (Maximum Power Point Tracking) algorithm that continuously tracks the peak power output under varying sunlight conditions (dawn, cloudy, dusk), increasing daily water yield by up to 20–30% compared to basic solar controllers.

Battery-Free Operation, Lower System Cost:Supports direct-coupled operation without batteries, eliminating expensive energy storage and charge controllers – reducing both initial investment and maintenance burden, ideal for remote areas and off-grid applications.

Suitable for Medium-to-Large Pump Applications:“045A” indicates a rated AC output current of 45 A, suitable for driving pumps up to ~22 kW (30 HP), perfect for medium-scale irrigation, village water supply, and large livestock watering systems.

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