Single phase hybrid on-grid & off-grid inverter, also called hybrid energy storage inverter, is an integrated bidirectional inverter integrating grid-connected power generation, battery charge & discharge, and off-grid backup power supply during blackouts. Equipped with built-in MPPT solar charge controller, it supports multi-energy input including PV panels, storage batteries, utility grid and backup generator.

When mains power is available, it works in grid-tied mode to realize self-consumption, surplus power export to grid and peak-valley energy storage for electricity cost saving. Once power failure occurs, it switches to independent off-grid mode within milliseconds to supply critical loads without interruption, meeting both power generation profit and emergency power demand. The unit outputs pure sine wave AC, compatible with all household and small commercial electrical appliances, equipped with full electrical safety protection and remote intelligent monitoring function.
