Residential

A BTM fixer upper! Patrick & Michelle Franco’s ageing solar system in Strathalbyn was producing far less than expected. After a site inspection we determined an old fuse had blown, isolating half the panels and resulting in huge amounts of lost generation over time. After replacing the fuse and rewiring the array to bring the system into line with current requirements, BTM installed an additional 7 Sunpower solar panels and replaced the ageing inverter with a brand new Fronius Primo having a fresh 10 year warranty. Always make sure your solar installer connects your system to the internet for monitoring or you could be stuck with inactive solar panels and be missing out on thousands of dollars of energy savings without even knowing!

With old and new working together this system is now producing over more clean energy than ever!

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!

3.2kW of Sunpower P-Series solar panels installed on a single phase property connected to a 2.5kW SMA Sunny Boy Inverter. Because of the long cable runs on the property, the system had to be carefully designed to prevent disturbance to the network voltage.

5.8kW of Sunpower P-Series solar panels installed on a rural dual phase property. Phase balanced with 2 x 2.5kW SMA Sunny Boy Inverters.
