Introduction
Due to the recent blackouts and load shedding in Australia, energy costs become higher.The project is for the purpose of providing higher quality reliable electrical power with lower costs.The aim of this project is to design, develop and implement a small scale standalone renewable nanogrid for households and small business applications. A traditional electrical grid can be referred as a typical centralised macrogrid while the nanogrid is a localised power distribution system that is less than 5kW. The nanogrid is a mobile system that can be deployed without additional electricity approval and with lower installation costs.
System Design
AC coupled (left) and DC coupled (right) Advantage of DC couple compare with AC couple: Easy to synchronise the system Easy to expand Less power transmission loss through the inverter Less cost due to the inverter more suitable for households applications level
The nanogrid system is setting up to 48V DC level for human safety operation and 1.3kW output power to satisfy household daily demand which is 14.2kWh in Australia , and central controller is monitoring and controlling voltage and current output from the converter and inverter to ensure the energy management of the system.

Component Testing
Conclusion
In general, the efficiency of the solar panel is 80% and an overall 90% average efficiency of the PV controller is achieved in the nanogrid solar system.The high efficiency PV controller is feasible and functional as required. Additionally, the efficiency of the wind generator system is varied from 42% to 82% based on the load, however, this controller is not stable enough to satisfy daily power demand.
Future works With the completion of preliminary testing of all components, the controller testing and validating of the battery. Assembly components into a cabinet, monitoring and energy management need to be further conducted.
