Single Phase Hybrid Inverter

Key Feature

INVTSolar's XD 3-6KTL is a new generation of single-phase energy storage inverter with enhanced performance. It can adapt to various residential energy storage applications, including simultaneous access of PV, battery, load, grid/diesel generator, built-in self-generation and self-consumption, peak shaving and valley filling, battery priority, backup power, and other operation modes. It also supports multiple units in parallel, AC couple, diesel generators, Anti-reflux, and other energy storage solutions.
