11PV 2.2kW MPPT Solar Pump Inverter – AC/DC Hybrid VFD Controller

Optimize your 3HP water pumping system with intelligent solar power conversion. The 11PV-2K2 delivers 99.6% MPPT tracking efficiency with seamless AC/DC hybrid operation, enabling direct solar drive for 220V single-phase or 380V three-phase pumps without battery storage. Cut operational costs by 70% while ensuring reliable irrigation through automatic grid backup when sunlight is insufficient.

Core Technology Advantages

Maximum Power Point Tracking (MPPT)

• 99.6% peak tracking efficiency maximizes energy harvest from PV arrays
