INVS M2 Series

The INVS M2 Series Off-Grid Inverter is a powerful energy storage solution offering high performance and flexible use for solar energy systems. With power options ranging from 3 kW to 5.5 kW, it provides reliable energy for both individual and commercial applications. Thanks to advanced MPPT technology, maximum efficiency is achieved from solar panels, while sensitive devices can be safely operated with pure sine wave output. System capacity can be increased with parallel operation support, easily adapting to larger energy needs. With built-in smart battery management and equalization functions, battery life is extended, and its compact design and user-friendly LCD screen offer easy installation and use.
