Optimize your large-scale irrigation and industrial water supply with our high-capacity 5.5KW Three-Phase Water Pump Inverter. Built for continuous, heavy-duty performance, this advanced controller transforms how you manage off-grid and hybrid pumping systems. At its core, the unit achieves a remarkable charging efficiency of ≥99%, ensuring that virtually every watt of harvested solar energy is converted into productive water flow.

The inverter is engineered to accommodate fluctuating power grids, accepting a broad AC input voltage range of 380V to 440V while consistently delivering a stable 380V three-phase output. This precise voltage regulation protects your pump motor from electrical stress and guarantees smooth, reliable operation.

A defining advantage of this 5.5KW model is its intelligent, universal battery management system. It automatically detects and adapts to various battery chemistries, including Gel, SLA, AGM, Flooded Water, and Lithium (LiFePO4). This flexibility allows you to seamlessly integrate existing lead-acid setups or upgrade to modern lithium storage without needing additional hardware.

Designed for harsh outdoor environments, the inverter features comprehensive safety protections against dry-running, over-voltage, and overheating. Its dynamic MPPT algorithm ensures maximum power extraction even during cloudy conditions. With a user-friendly display and rugged build quality, this 5.5KW inverter offers a dependable, energy-efficient solution for demanding water management projects.
