Supply and install inverters on racking to the clients roof
These are the boxes that convert the direct current from the panels into house hold friendly alternating current.
Australia has in the last couple years moved in line with the rest of the world and micro inverters are now used. They are much smaller and go on each panel.
The advantages are they do less work so last much longer, 25 year warranties!
Additionally they allow us to monitor each panel individually.See our Inverters Range
