Grid-connected and off-grid energy storage inverter

4 FAQs about [Grid-connected and off-grid energy storage inverter]

What is a grid-tied inverter?

A grid-tied inverter solely designed for solar-to-grid applications, with no battery support. It provides efficient solar energy conversion and direct grid feed-in but cannot store energy. Ideal for locations with stable grid access and net metering policies, where users aim to offset electricity bills without investing in battery systems.

What is an off-grid inverter?

Though fundamentally an off-grid inverter, this versatile model features grid input support—allowing it to draw power from the grid when solar and battery resources are insufficient. Commonly known as an off-grid hybrid inverter, it combines solar + battery + optional grid power, ensuring uninterrupted energy supply.

What is an on-grid hybrid inverter?

This on-grid hybrid inverter is perfect for homeowners or businesses seeking net metering benefits while maintaining power during outages. A grid-tied inverter solely designed for solar-to-grid applications, with no battery support. It provides efficient solar energy conversion and direct grid feed-in but cannot store energy.

How does a grid inverter work?

The grid inverter functions in two modes: as a front-end rectifier when transferring power from the grid to the battery, and as a voltage source inverter when feeding power from the PV/battery back to the grid. It incorporates a full-bridge PWM inverter with an LC output filter to inject synchronized sinusoidal current into the grid.
