What Are Off-grid Inverters And Hybrid Inverters?

With the rapid development of renewable energy, energy storage inverters have become an important bridge connecting renewable energy systems to the grid or load. Among them, off-grid energy storage inverters and hybrid energy storage inverters are two common types. So what are they? What are the differences?

Off-grid Energy Storage Inverter

• Working Principle

The off-grid energy storage inverter system is like a large “rechargeable battery”, which stores excess power from the grid or renewable energy sources (e.g., solar, wind) in a battery bank when it is generated. When electricity is needed, the DC power in the battery will be converted to AC power for use in homes, factories or other equipment.

•  Application Scenarios

Off-grid energy storage inverters are especially suitable for those remote areas without grid access. In mountainous areas or deserts, power supply is often a problem, but with off-grid storage inverters, people can enjoy stable and reliable power.

Hybrid Energy Storage Inverter

• Working principle

The hybrid energy storage inverter is “smarter” than the off-grid energy storage inverter. It not only provides power when the grid is down, but also injects renewable energy into the grid when it is up and running. It is like a “double insurance” for the family, which can be self-sufficient in times of emergency and contribute to the grid in normal times.

•  Application Scenarios

Hybrid storage inverters are suitable for applications where both on-grid and off-grid requirements need to be met. For example, in a solar power station, when there is enough sunlight, excess power can be injected into the grid; at night or on cloudy days, power can be taken from the grid or used from the battery bank.
