Paul Buise was looking for a clean energy supply to go with his newly constructed Energy Efficient House in Waggrakine.
BTM installed 6.5kW of Trina Solar Panels connected to a 5kW Redback Smart Hybrid Inverter. This is connected to 7.2kWh of Lithium Iron Phosphate batteries that not only store excess solar energy for use through the night but also provide backup power when the grid goes down.
The energy requirements of the house are modest because of the passive design using natural light and rammed earth walls. Energy that is not stored in the battery or used by the loads in the house is sent back to the grid meaning many days Paul is getting paid more by the retailer than the charges to be connected to the grid!
