A single inverter with PV, battery and AC ports, combining MPPT charging, battery inversion and backup output.

## In plain English

### What does Hybrid inverter mean?

A hybrid inverter combines a solar maximum power point tracker, a bidirectional battery converter and an AC inverter in one unit. It typically has three port types: PV DC input, battery DC terminals and an AC grid connection, with many models adding a separate backup or essential load output that stays supplied with operating power during a network outage.

### A simple example

Single-line diagrams show one inverter block with multiple DC inputs and one or two AC outputs, and the internal DC bus is sometimes drawn as a dashed line. The essential load board, isolators for each port and the grid connection point should all be shown.

### What the drawings help you do

The symbol does not state how fast the backup output transfers, whether the battery can be charged from the grid, or what export limit applies. Those depend on the settings and on network operator rules, not on the block itself.

### This particular reference

A single inverter with PV, battery and AC ports, combining MPPT charging, battery inversion and backup output. A hybrid inverter includes PV and battery ports in one unit; an inverter-charger usually has a battery port only and relies on separate solar chargers.

### Terms

- DC: Direct current: electricity flowing in one direction.
- AC: Alternating current: electricity whose direction changes periodically.
- Terminal: An identified point where a conductor connects.

## What it represents

A hybrid inverter combines a solar maximum power point tracker, a bidirectional battery converter and an AC inverter in one unit. It typically has three port types: PV DC input, battery DC terminals and an AC grid connection, with many models adding a separate backup or essential load output that stays energised during a network outage.
Single-line diagrams show one inverter block with multiple DC inputs and one or two AC outputs, and the internal DC bus is sometimes drawn as a dashed line. The essential load board, isolators for each port and the grid connection point should all be shown.
The symbol does not state how fast the backup output transfers, whether the battery can be charged from the grid, or what export limit applies. Those depend on the settings and on network operator rules, not on the block itself.

## How to read it

- Identify every DC and AC port and its isolator.
- Separate the backup output circuits from normal circuits.

## Information to show or reference

- State PV, battery and AC ratings.
- Show backup load board and isolators.
- Reference export limit and transfer behaviour.

## Important distinction

A hybrid inverter includes PV and battery ports in one unit; an inverter-charger usually has a battery port only and relies on separate solar chargers.
