Recycle batteries and produce a backup power source.
- Parts List
- Batteries (4 off 12Volt 200ah)
- Solar Panels (6 of 250 watt)
- Wind Turbine (400 watt max)
- Smart Controller (talks to smart home)
- Scope of project
- Harness and direct solar or wind energy to recharge a battery / inverter system.
- Send battery power to a Power inverter (2kw grid tied).
- Manage Power to turn on only when needed, eg. when cooking.
- Interact with other services within household using Home Assistant and ESP Home (Smart Home services).
- Method used
- when sun up batteries charged from solar and at night the wind turbine will take over.
- After sunset the batteries that are available are be directed to a power inverter which can produce up to 2kw of energy to add the the house grid.
- Detect when house draws high energy switch on the inverter to reduce load from the grid especially during cooking times.
