What is the difference between a single phase inverter and a hybrid inverter?

A single-phase inverter and a hybrid inverter are two different types of solar inverters with distinct purposes and capabilities.

A single-phase inverter is a standard solar inverter that converts the DC (direct current) power generated by solar panels into AC (alternating current) that is suitable for use by household appliances or to be fed back into the grid. It is ideal for small- to medium-sized residential systems that are connected to the grid and don't require energy storage. Single-phase inverters typically come in a range of power output ratings and are designed to work with a specific number of solar panels.

On the other hand, a hybrid inverter is a type of solar inverter that incorporates both DC and AC coupled energy storage capabilities into a single unit. It can be used in both grid-tied and off-grid battery backup systems. In addition to converting DC power to AC power, hybrid inverters can also store surplus energy from solar panels in a battery for later use. It provides an uninterrupted power supply during a power outage and can provide significant cost savings by reducing reliance on grid-connected energy.

Hybrid inverters are also capable of managing multiple sources of power input, such as utility power, solar panels, and batteries and can switch seamlessly between the sources as needed. It provides the flexibility to work with various energy-generation and storage sources.

In conclusion, a single-phase inverter is designed to convert DC power to AC for small to medium-sized residential systems while a hybrid inverter is designed to provide additional functionality, incorporating energy storage and multiple power inputs in both residential and commercial sites.
