Hybrid inverter

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.

Drawing use: SLD
Application: Microgrid systems
Reference family: IEC / IEEE / ANSI / Manufacturer

A distinction that matters

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.

Bidirectional inverter-charger

An inverter-charger contains one bidirectional power stage between a battery and an AC output, together with an internal transfer relay connecting the AC input to the output when a valid source is present. With the source available it passes power through and charges the battery; without it, it opens the relay and inverts from the battery.

Reference family: IEC / IEEE / ANSI / Manufacturer

A distinction that matters

An inverter-charger has an internal transfer relay and charger; a plain DC-to-AC inverter only converts battery power to AC.
