- Hybrid Generator
The term hybrid generator refers to generators within a hybrid power system. The 'hybrid' part of the name refers to the fact that these power systems usually involve another form of energy production, such as use of solar panels or wind turbines. These power generators work in unison within the system to maximize fuel economy. To accommodate multiple sources of power, these systems involve a computerized controller, which controls operation, usage, and energy production.
Hybrid Generators generally have reduced fuel consumption, reduced maintenance, and provide highly reliable electric power, as compared with non-hybrid generators. This is due to a difference in the way which it is operated, when compared to traditional generators.
Most engine driven electric generators run continuously and at a high / fixed RPM this results in significant quantities of fuel being consumed even if the loads are low.
A hybrid generator automatically shuts the engine off when demand is low. When power from the engine is needed, it starts automatically and runs at the minimum RPM to provide maximum fuel economy. Running the engine slower, and shutting the engine off when loads are low, results in dramatic fuel savings, lower maintenance and increased engine life.
Components of the hybrid generator generally consist of a controller/ combustion engine / DC generator / batteries / DC to AC inverter. The engine produces DC power to charge the batteries and run the inverter when needed. The Inverter converts the stored DC power to usable AC electric energy. Having battery storage also helps the engine absorb load spikes. The controller monitors the system starting and stopping the engine as need.
Because hybrid generators already have an inverter and battery storage, energy from wind or solar power can be connected directly to the generator for increased efficiency.
