Hybrid AC and DC Coupled Off-Grid Systems

Example of a hybrid system with AC and DC coupling

Hybrid systems with AC and DC coupling are particularly well suited for coupling alternating current loads in the medium power range with DC energy sources. In hybrid systems, the battery can be charged via a generator at the same time. Hybrid systems are suited to supplying remote loads and satisfy higher energy demands. Accordingly, hybrid systems are used in ranches, smaller factories and on farms.

When designing the system, it must be ensured that the nominal power of the inverter is sufficient to supply the power to be consumed by the intended loads. Even if there is more power available from a PV system or wind turbine system, the inverter is the decisive factor in how much power is available on the AC side. The design of hybrid systems is much more complex than the design of purely AC coupled systems.
