What is Hybrid inverter ?

A Hybrid inverter is an intelligent inverter that enables the storage of excess solar energy in a battery system for self-use. Hybrid inverters function like a common grid-tie solar inverter but can generally operate in one of several different modes depending on the application, this includes battery backup mode which provides a limited level of backup power in the event of a blackout. Most hybrid inverters can also operate without a battery and function just like a grid-tie solar inverter by exporting excess solar energy to the utility grid.

Having all the key features for solar and battery storage in one simple plug-and-play inverter means hybrid inverters are generally much lower cost and easier to install compared to more complex battery storage systems which often require multiple inverters. However, they do have several limitations and are generally not recommended to be used for off-grid solar systems.

Most hybrid inverters can be programmed to function in four different modes:

Grid-tie mode – Functions like a normal solar inverter (no battery)

Hybrid mode – Stores excess solar energy during the day to be used in the evening to increase self-sufficiency.

Backup mode – Functions like a normal solar inverter when the grid is connected and automatically switches to backup power mode during a grid outage

Off-grid mode* – Operates much like an off-grid inverter and uses excess solar to charge the battery and power the loads without a grid-connection.

* Only a select few hybrid inverters are designed to be used for off-grid solar power system and have the capacity to start and run a backup power source if required. Hybrid inverters with off-grid mode include Ingeteam and Sol-Ark.
